Just the raw implementation + basic docs + basic tests that run against
the official registry (when/if we have our own MCP registry SDK, we
might want to switch to using that)
The next step will probably be some tooling to attempt to automatically
transform MCP server metadata into usable instances of `McpTransport`
(for building an actual MCP client that talks to the server) in cases
when it's possible...

## Issue
Closes #3635
## Change
Added support for receiving generated images from Gemini's image
generation models (e.g., gemini-2.5-flash-image-preview).
**Changes made:**
- Modified `PartsAndContentsMapper.fromGPartsToAiMessage()` to process
`inlineData` containing generated image data
- Added `GeneratedImageHelper` utility class for easy access to
generated images from `AiMessage.attributes()`
- Generated images are stored in `AiMessage.attributes()` under key
"generated_images"
- Solution works for both streaming and non-streaming responses
- Maintains full backward compatibility with existing code
**Technical details:**
- Processes Gemini response parts with `inlineData` and image mime types
- Converts base64 image data to `Image` objects
- Uses existing `attributes` mechanism to avoid breaking changes
- Includes comprehensive test coverage
This enables full Gemini image generation support while preserving the
existing architecture.

Closes #
## Change
<!-- Please describe the changes you made. -->
I started working on this change with the idea of making the
`HumanInTheLoop` non-blocking, meaning that the invocation is made on
another thread and the agentic system execution blocks only when the
result provided by the `HumanInTheLoop` is really necessary because it
is read as an input for another agent. Then I figured out that this
non-blocking feature was quite useful, so I decided to extend it to all
agents. In this way, for instance, it is possible to achieve a parallel
execution without using the parallel workflow, but simply putting the
non-blocking agents in sequence.

### Summary
The Agents tutorial references a `StyleEditor` agent but does not
include its implementation.
This PR adds the missing `StyleEditor` interface, making the tutorial
complete and runnable.
### Details
The implementation was adapted from the example in
[`Agents.java`](https://github.com/langchain4j/langchain4j/blob/main/langchain4j-agentic-a2a/src/test/java/dev/langchain4j/agentic/a2a/Agents.java).
### Why
- Completes the tutorial so it is self-contained.
- Reduces confusion for new users.
- Maintains consistency with other agent interfaces such as
`AudienceEditor`.

## Issue
Closes https://github.com/langchain4j/langchain4j/issues/124
## Change
This is a rework from scratch of what has been done in
https://github.com/langchain4j/langchain4j/pull/2291 and
https://github.com/langchain4j/langchain4j/pull/2772 also based on the
comments made during the review of those pull requests.
As I described in the Javadocs, here I added a `ReturnBehavior` enum
(names are very questionable and I'm open to change them if you have
better proposals) implementing 3 different behaviors for tools:
```
/**
* Return behavior of the tool.
* - If {@link ReturnBehavior#TO_LLM} is used (default), the value returned by the tool is sent back to the LLM for further processing.
* The LLM invocation will directly return the value returned by the last invoked tool, instead of the one further manipulated by the LLM,
* if and only if all the tools invoked by the LLM to fulfill the request are marked with {@link ReturnBehavior#DIRECT}.
* - If {@link ReturnBehavior#IMMEDIATE} is used, returns immediately to the caller the value returned by the tool without
* allowing the LLM to further processing it.
*
* @return return behavior of the tool.
*/
ReturnBehavior returnBehavior() default ReturnBehavior.TO_LLM;
```
The tests that I added should also help to clarify how this works.
Regarding the actual need for this feature, what has been discussed in
[this
article](https://quarkus.io/blog/agentic-ai-with-quarkus-p3/#comparing-the-workflow-and-agentic-approaches)
provides another example of a situation where this could be useful.

## Issue
Fixes#3596
## Change
Fix typo in pom type configuration tag
Corrects a typo in the documentation where the XML tag for pom type was
incorrectly written as `<typ>pom</typ>` instead of the proper
`<type>pom</type>`.
This change:
- Fixes invalid XML syntax in the configuration example
- Ensures consistency with standard Maven configuration conventions
- Prevents potential implementation issues when developers copy-paste
the snippet

## Issue
Closes#3363
## Change
Introduced `ToolArgumentsErrorHandler` and `ToolExecutionErrorHandler`
that can be configured on the AI Service to handle errors related to
tools:
- when tool arguments cannot be parsed/prepared in order to execute a
tool
- when something wrong happens during tool execution
Currently, there are two ways to handle errors:
1. Throw an exception: this will stop the AI service flow.
2. Return a text message (e.g., an error description) that will be sent
back to the LLM,
allowing it to respond appropriately (for example, by correcting the
error and retrying).
## Example
```java
Assistant assistant = AiServices.builder(Assistant.class)
.chatModel(chatModel)
.tools(tools)
.toolArgumentsErrorHandler((error, context) -> ToolErrorHandlerResult.text("Can't parse tool arguments: " + error.getMessage()))
.toolExecutionErrorHandler((error, context) -> ToolErrorHandlerResult.text("Can't execute tool: " + error.getMessage()))
.build();
```
## Breaking Changes
This PR requires breaking changes in
`DefaultMcpClient.executeTool(ToolExecutionRequest)`: instead of
returning strings with error messages, `ToolArgumentsException`,
`ToolExecutionException` or `RuntimeException` will be thrown in case of
errors.

## Change
The vast majority of long running operations, eventually running in
parallel, are I/O tasks and for this reason it is very beneficial to
execute them on virtual threads.
This pull request introduces a default executor, that should be used by
all parallel operations performed by langchain4j. When possible, i.e.
when running on Java 21+, this executor is a pool of virtual threads,
otherwise normal cached platform threads are used.
This pull request also contains a minor change in the agentic parallel
workflow, making it to use a more generic `Executor` instead of a more
restrictive `ExecutorService`.

## Change
Added `JsonRawSchema` so that any existing raw schema (specified as a
`String`) can be used without reproducing it manually using the
`JsonSchemaElement`s builder.
Background is that we already have huge and well defined schemas in
resource-files, such as this
[process](https://json-schema.axonivy.com/process/12.0.0/process.json)
example.
Manually reproducing them is a show stopper.

## Change
The `McpToolProvider` has an implementation of a `ToolExecutor` used
internally.
This PR extracts it to a `McpToolExecutor` so it can be used outside the
`McpToolProvider`.
**Why doing this?**
To register tools for an AI service, there are a lot of different ways:
- using `AiService.tools(Object...)`
- using `AiService.toolProvider(ToolProvider)`
- using `AiSerice.tools(Map<ToolSpecification, ToolExecutor>)`
We use the latter in our code as we handle dynamically multiple types of
tools (WebSearch, MCP Client, custom tools, etc.). To be able to use it,
we have our own copy of the currently private MCP ToolExecutor.
With the change of this PR, we would be able to use the newly extracted
`McpToolExecutor` to register tools using
`AiSerice.tools(Map<ToolSpecification, ToolExecutor>)` instead of
copying its code to a custom class.

## Issue
Closes#3290
## Change
Added an option to execute tools concurrently:
```java
/**
* By default, when the LLM calls multiple tools, the AI Service executes them sequentially.
* If you enable this option, tools will be executed concurrently (with one exception - see below),
* using the default {@link Executor}.
* You can also specify your own {@link Executor}, see {@link #executeToolsConcurrently(Executor)}.
* <ul>
* <li>When using {@link ChatModel}:</li>
* <ul>
* <li>When the LLM calls multiple tools, they are executed concurrently in separate threads
* using the {@link Executor}.</li>
* <li>When the LLM calls a single tool, it is executed in the same (caller) thread,
* the {@link Executor} is not used to avoid wasting resources.</li>
* </ul>
* <li>When using {@link StreamingChatModel}:</li>
* <ul>
* <li>When the LLM calls multiple tools, they are executed concurrently in separate threads
* using the {@link Executor}.
* Each tool is executed as soon as {@link StreamingChatResponseHandler#onCompleteToolCall(CompleteToolCall)}

* <li>When the LLM calls a single tool, it is executed in a separate thread using the {@link Executor}.

## Issue
Closes https://github.com/langchain4j/langchain4j/issues/2790
## Change
Implemented support for streaming partial and complete tool calls in
`StreamingChatResponseHandler` by adding
2 new callbacks:
```java
/**
* This callback is invoked each time the model generates a partial tool call,
* which contains a single token of the tool's arguments.
* It is typically invoked multiple times for a single tool call
* until {@link #onCompleteToolCall(CompleteToolCall)} is eventually invoked,
* indicating that the streaming for that tool call is finished.
* <p>
* Here's an example of what streaming a single tool call might look like:
* <pre>
* 1. onPartialToolCall(index = 0, id = "call_abc", name = "get_weather", partialArguments = "{\"")
* 2. onPartialToolCall(index = 0, id = "call_abc", name = "get_weather", partialArguments = "city")
* 3. onPartialToolCall(index = 0, id = "call_abc", name = "get_weather", partialArguments = ""\":\"")
* 4. onPartialToolCall(index = 0, id = "call_abc", name = "get_weather", partialArguments = "Mun")
* 5. onPartialToolCall(index = 0, id = "call_abc", name = "get_weather", partialArguments = "ich")
* 6. onPartialToolCall(index = 0, id = "call_abc", name = "get_weather", partialArguments = "\"}")
* 7. onCompleteToolCall(index = 0, id = "call_abc", name = "get_weather", arguments = "{\"city\":\"Munich\"}")
* </pre>
* <p>
* If the model decides to call multiple tools, the index will increment, allowing you to correlate.
* <p>
* Please note that not all LLM providers stream tool calls token by token.
* Some providers (e.g., Bedrock, Google, Mistral, Ollama) return only complete tool calls.
* In those cases, this callback won't be invoked - only {@link #onCompleteToolCall(CompleteToolCall)}
* will be called.
*
* @param partialToolCall A partial tool call that contains
* the index, tool ID, tool name and partial arguments.
* @since 1.2.0
*/
@Experimental
default void onPartialToolCall(PartialToolCall partialToolCall) {
}
/**
* Invoked when the model has finished streaming a single tool call.
*
* @param completeToolCall A complete tool call that contains
* the index, tool ID, tool name, and fully assembled arguments.
* @since 1.2.0
*/
@Experimental
default void onCompleteToolCall(CompleteToolCall completeToolCall) {
}
```

## Issue
Feature #3331
## Change
AWS Bedrock has introduced API key support on 7/7, simplifying
authentication for the Amazon Bedrock API. To enable this new feature in
langchain4j, this update bumps the required aws sdk version to
"2.31.74". It has been tested and worked as expected with new
`AWS_BEARER_TOKEN_BEDROCK` environment variable.
Fixed two spelling errors in the document.

Fixes https://github.com/langchain4j/langchain4j/issues/2767
Wanted to get some early feedback before I proceed to creating more
tests and documentation (and probably extend it to prompts too).
The idea is that the user can now, when creating a `McpToolProvider`,
enable the `exposeResourcesAsTools` option. If this is enabled, then the
tool provider will expose two extra 'synthetic' tools:
- `list_resources` to obtain a list of all resources available for all
MCP clients that are wrapped into this tool provider
- `get_resource` to render a specific resource - it takes two arguments:
- resource URI (I chose URI instead of the name to be able to retrieve
[resource
templates](https://modelcontextprotocol.io/specification/2025-06-18/server/resources#resource-templates)
too in the same way)
- name (`key`) of the MCP client that this resource belongs to
The result of `list_resources` is JSON and looks something like this:
```
[ {
"mcpServer" : "alice",
"uri" : "file:///info",
"uriTemplate" : null,
"name" : "basicInfo",
"description" : "Basic information about Alice",
"mimeType" : "text/plain"
}, {
"mcpServer" : "bob",
"uri" : "file:///info",
"uriTemplate" : null,
"name" : "basicInfo",
"description" : "Basic information about Bob",
"mimeType" : "text/plain"
} ]
```
I tested this with `gpt-4o-mini` and it understood how to find and
retrieve a relevant resource (see
`McpResourcesAsToolsTestBase#integrationTestWithAiService` for
demonstration)
So a resource is identified by uri AND the name of the mcp connection,
because it may happen that two servers will have resources on the same
URI.
When it's a resource, then `uri` is specified here, if it's a template,
then `uriTemplate` is specified instead.
Note: another way would be to expose a separate synthetic tool for each
resource instead of having `get_resource` over all of them. That would
render it unnecessary to invent a new JSON schema for the
`list_resources`, but I'm afraid that there will, in the real world, be
too many resources, and exposing a tool for each separately would
explode the context size.
# Refactor moderation handling and improve exception details
## Issue #3025
The ModerationException does not contain structured information about
the issues flagged. The first step is to include the Moderation object
in the exception.
Next, potential improvement should be promoting ModerationResult from
the openai module to the core module and enhancing or replacing the
Moderation class.
## Change
- Update `Moderation` as a serializable class with nullable support for
flagged text.
- Enhanced `ModerationException` to include moderation details for
better debugging and testing.
- Updates include corresponding tests and minor formatting improvements
across related files.
- Updated documentation

## Issue
Closes#2954
## Change
### Setting custom chat request parameters
When using `OpenAiChatModel` and `OpenAiStreamingChatModel`, one can now
set custom chat request parameters (in the JSON body of the HTTP
request). Here is an example of how to enable web search:
```java
record ApproximateLocation(String city) {}
record UserLocation(String type, ApproximateLocation approximate) {}
record WebSearchOptions(UserLocation user_location) {}
WebSearchOptions webSearchOptions = new WebSearchOptions(new UserLocation("approximate", new ApproximateLocation("London")));
Map<String, Object> customParameters = Map.of("web_search_options", webSearchOptions);
// Alternatively, custom parameters can also be specified as a structure of nested maps
Map<String, Object> customParameters = Map.of(
"web_search_options", Map.of(
"user_location", Map.of(
"type", "approximate",
"approximate", Map.of("city", "London")
)
)
);
ChatRequest chatRequest = ChatRequest.builder()
.messages(UserMessage.from("Where can I buy good coffee?"))
.parameters(OpenAiChatRequestParameters.builder()
.modelName("gpt-4o-mini-search-preview")
.customParameters(customParameters)
.build())
.build();
ChatModel model = OpenAiChatModel.builder()
.apiKey(System.getenv("OPENAI_API_KEY"))
.logRequests(true)
.logResponses(true)
.build();
ChatResponse chatResponse = model.chat(chatRequest);
```
This will produce an HTTP request with the following body:
```json
{
"model" : "gpt-4o-mini-search-preview",
"messages" : [ {
"role" : "user",
"content" : "Where can I buy good coffee?"
} ],
"web_search_options" : {
"user_location" : {
"type" : "approximate",
"approximate" : {
"city" : "London"
}
}
}
}
```
### Accessing raw HTTP responses and Server-Sent Events (SSE)
One can now access the raw HTTP response (for `OpenAiChatModel`) and raw
Server-Sent Events (for `OpenAiStreamingChatModel`):
```java
// For OpenAiChatModel:
SuccessfulHttpResponse rawHttpResponse = ((OpenAiChatResponseMetadata) chatResponse.metadata()).rawHttpResponse();
System.out.println(rawHttpResponse.body());
System.out.println(rawHttpResponse.headers());
System.out.println(rawHttpResponse.statusCode());
// For OpenAiStreamingChatModel:
List<ServerSentEvent> rawServerSentEvents = ((OpenAiChatResponseMetadata) chatResponse.metadata()).rawServerSentEvents();
System.out.println(rawServerSentEvents.get(0).data());
System.out.println(rawServerSentEvents.get(0).event());
```

## Change
This PR fixes a small typo in the BOM dependency declaration in the
community POM document.
## Change
- Removed deprecated APIs
- Deprecated constructors accepting many parameters in favour of ctors
accepting single builder
- Decreased default connect timeout from 60 to 15 seconds
- Added support for model listeners
- Implemented propagation of user exceptions from
`StreamingChatResponseHandler`'s `onPartialResponse` and
`onCompleteResponse` methods into `onError`
- Streaming models: implemented exception mapping, see
`DefaultExceptionMapper` for more info
- Slight refactoring and cleanup

Updated the tutorial documentation to clarify the description of
`EmbeddingStore.removeAll(Collection<String> ids)`.
**Before:**
> EmbeddingStore.removeAll(Collection<String> ids) removes multiple
Embeddings from the store by ID
**After:**
> EmbeddingStore.removeAll(Collection<String> ids) removes all
embeddings from the store whose IDs are present in the given collection.
This improves clarity and aligns better with the actual method behavior.

Guardrails support.
I also introduced a new `langchain4j-test` module which can be a future
place to put in some testing utilities. For now I have several
assertj-based assertion classes that can be used for asserting
guardrails. (see
https://docs.quarkiverse.io/quarkus-langchain4j/dev/guardrails.html#_unit_testing
for current details).
Additionally, I've introduced a new `integration-tests` where we can
build various sets of test suites (think things that use/need
`ServiceLoader`s). This way we can test various implementations of
things for frameworks that may extend LangChain4j (Quarkus, Spring,
etc).
I've tried to include as much "genericism" as I can into this so that
downstream frameworks can re-use this without having to re-implement.
I'll have @geoand / @cescoffier review this too before merging.
## To-do list
- [x] Initial scaffolding for being able to define guardrails
- [x] Guardrail testing utilities
- [x] Wire guardrails into `AiService`s via annotations
- [x] Wire guardrails into `AiService`s using the builder
- [x] Handle output guardrails on streaming responses
- [x] Lots of tests
- [x] Documentation
Fixes#2549

## Change
- Removed deprecated `Bedrock*ChatModel` model classes using invoke API
(please use `BedrockChatModel` and `BedrockStreamingChatModel` instead)
- Mapped Bedrock-specific exceptions to LC4j generic ones (see
`BedrockExceptionMapper` for more details)
- `BedrockTitanEmbeddingModel`: removed outdated default value for
`model` (please specify it explicitly)

## Change
Migrated `langchain4j-google-ai-gemini` from using JDK's `HttpClient` to
using `dev.langchain4j.http.client.HttpClient`.
This simplifies the implementation of the module and allows using other
HTTP clients and better integrate into frameworks.
This PR also fixes the issue with streaming. Now streaming response is
handled in a separate thread (previously streaming was handled in the
same thread which led to issues like frozen UI).
Exceptions are now also mapped using default exception mapper.

## Issue
Closes#3070
## Change
- Implemented full support of chat API for Azure OpenAI module
- Implemented exception mapping for Azure OpenAI module
- Refactorings, cleanup of deprecated APIs, etc
## Breaking Changes
- Replaced multiple constructors having lots of arguments with a single
constructor accepting a builder
- Removed default values for `deploymentName` parameter (please specify
it explicitly)
- Mapped Azure-specific exceptions to LC4j generic ones (see
`InternalAzureOpenAiExceptionMapper` for more details)
- Removed deprecated `responseFormat(ChatCompletionsResponseFormat)`
methods from builders (please use `responseFormat(ResponseFormat)`
instead)

`AzureOpenAiChatModelName`, `AzureOpenAiEmbeddingModelName`,
`AzureOpenAiImageModelName` and `AzureOpenAiLanguageModelName` instead)
- `AzureOpenAiStreamingChatModel` and
`AzureOpenAiStreamingLanguageModel`: `TokenUsage` will not be calculated

- `AzureOpenAiStreamingChatModel.Builder`: removed deprecated
`useAsyncClient` and `openAIClient` methods (please use
`openAIAsyncClient` instead)
- `AzureOpenAiTokenCountEstimator`: removed deprecated no-arg
constructor (please specify model name explicitly)
- Fix: when LLM decides to execute tools, `FinishReason` is now
`TOOL_EXECUTION` (instead of `STOP` previously)

## Issue
Addresses an enhancement in
[3175](https://github.com/langchain4j/langchain4j/issues/3175)
## Change
Adds pdf file handling to the openai module.
Looking for some feedback as the openai files handling requires filename
to be passed along with the request, which is currently not a field on
the PdfFileContent.

### Summary
This PR updates the documentation for the `Metadata` key-value map to
include `UUID` as one of the supported value types.
### Details
The current documentation lists the supported value types as:
- String
- Integer
- Long
- Float
- Double
However, `UUID` is already supported in the implementation but missing
from the docs.
This update adds `UUID` to the list of supported types in the
documentation to improve clarity and accuracy.
This PR does not change any code logic, only updates the documentation.

Fix broken anchor link in RAG tutorial documentation
What’s changed: Updated the anchor link in the RAG tutorial from
/tutorials/rag#rag-apis to /tutorials/rag#core-rag-apis to correctly
point to the "Customizable RAG" section.
Co-authored-by: Harikrishna <harikrishna.gurram@walmart.com>
This PR corrects an incomplete usage of the @P annotation in the
documentation.
## Issue
In the example:
```
@Tool
void getTemperature(String location, @P(required = false) Unit unit) {
...
}
```
The @P annotation omits the required value() element, which leads to a
compilation error because value() is a mandatory parameter in the @P
annotation definition.
## Fix
Updated the annotation usage to:
```
@Tool
void getTemperature(
String location,
@P(value = "Unit of temperature (e.g., Celsius or Fahrenheit)", required = false) Unit unit
) {
...
}
```

## Change
Fixed split package issue between `langchain4j-vertex-ai` and
`langchain4j-vertex-ai-gemini` modules.
Both modules have root package with the same name:
`dev.langchain4j.model.vertexai`.
Root package for `langchain4j-vertex-ai-gemini` was changed to
`dev.langchain4j.model.vertexai.gemini` to fix the issue.

## Issue
Fixes https://github.com/langchain4j/langchain4j/issues/2918
## Change
- Changed `maxRetry` parameter semantics from "max attempts" to "max
retries".
- Changed default value of the `maxRetry` parameter from 3 to 2, but it
does not change the default behaviour. When `maxRetries` parameter is
not specified explicitly, it will attempt to execute up to 3 times (as
it was before).
## Breaking Change
If you do **_not_** specify `maxRetries` parameter explicitly, there is
no breaking change and you do not need to do any changes to your code.
If you specify `maxRetries` parameter explicitly, you will need to
reduce it by 1, example:
```java
// before
OpenAiChatModel.builder()
.apiKey(System.getenv("OPENAI_API_KEY"))
.modelName(GPT_4_O_MINI)
.maxRetries(1)
.build();
// after
OpenAiChatModel.builder()
.apiKey(System.getenv("OPENAI_API_KEY"))
.modelName(GPT_4_O_MINI)
.maxRetries(0)
.build();
```

## Issue
<!-- Please specify the ID of the issue this PR is addressing. For
example: "Closes #1234" or "Fixes #1234" -->
Closes#2633
## Change
I added the glue-code needed to pass a JSON schema from a `ChatRequest`
to the Mistral API. I tried to follow established patterns for setting
this up, e.g.:
```java
MistralAiChatModel.builder()
.apiKey(System.getenv("MISTRAL_AI_API_KEY"))
.modelName(MISTRAL_SMALL_LATEST)
.temperature(0.1)
.logRequests(true)
.logResponses(true)
.supportedCapabilities(Capability.RESPONSE_FORMAT_JSON_SCHEMA) // this enables structured output
.build()
```
When no schema is given in the `ChatRequest`, the old behavior of
following the format given in model's `responseFormat` is executed.

## Issue
Closes#1882
Partially addresses #916
## Change
So far Structured Outputs with JSON schema supported only a (single)
POJO as a return type.
This PR adds support for the following types:
- `List<POJO>`, `Set<POJO>`
- `Enum`, `List<Enum>`, `Set<Enum>`
- `List<String>`, `Set<String>`
- `boolean`, `Boolean`
- `int`, `Integer`
- `long`, `Long`
- `float`, `Float`
- `double`, `Double`
This PR also refactors `ServiceOutputParser`, `OutputParserFactory` and
`OutputParser`s.

## Changes
- Made POJO fields optional by default for structured outputs. For
"strict mode", optionality is emulated via union of the type and `null`
(e.g., `"type":["string", "null"]` for optional `String` field). Note:
nothing changes for tools, all POJO fields stay required by default.
- Added support for `@JsonProperty(required = true/false)` for
structured outputs and tools
- `LocalTime`/`LocalDateTime`: `second`/`nano` now have default value of
`0` if not present in generated JSON
- OpenAI: internal JSON schema hierarchy in the client was removed in
favour of a common mapping (as a `Map<String, Object>`) to simplify and
reduce duplication

## Changes
- Removed `JsonSchemaProperty` and `ToolParameters` classes which were
deprecated in previous releases. If you want to specify tool parameters
in `ToolSpecification`, use `JsonObjectSchema`:
```java
ToolSpecification toolSpecification = ToolSpecification.builder()
.name("getWeatherForecast")
.description("Get the weather forecast for a location")
.parameters(JsonObjectSchema.builder()
.addStringProperty("location", "the location to get the weather forecast for")
.required("location")
.build())
.build();
```
- Removed a few methods from `Tokenizer` to estimate token count of
tools (this functionality will not be supported any more)
- `AzureOpenAiStreamingChatModel`: removed the use of `Tokenizer`
methods that estimate token counts for tools (described above), so
estimated `TokenUsage` does not include tools now. This should be fixed
by https://github.com/langchain4j/langchain4j/issues/1068 in the future

## Issue
Closes#1042Closes#1810
## Change
- Migrated `langchain4j-core`, `langchain4j` and `langchain4j-jlama`
modules from Gson to Jackson. This is supposed to be a non-breaking
change, but there might be some corner cases that I have missed, so
please report if your use case stopped working or you face any other
issue related to this change.
- Now using `JsonCodec` to deserialize tool arguments
- Migrated `langchain4j-vertex-ai` module from internal `Json` util to
use it's own Gson mapping logic
## Breaking Changes
- Removed `Json.toInputStream` and `JsonCodec.toInputStream` methods as
they are not required

## Issue
Closes#2468
## Changes
1. This PR is a continuation of efforts started in
https://github.com/langchain4j/langchain4j/pull/2413
2. When using `langchain4j-open-ai`, all `OpenAi*Model`s are now using
`java.net.http.HttpClient` instead of OkHttp/Retrofit by default. You
also have an option to [customize it or plug in any other HTTP
client](https://docs.langchain4j.dev/tutorials/customizable-http-client).
3. When using `langchain4j-open-ai-spring-boot-starter`, all
`OpenAi*Model`s are now using Spring's `RestClient` instead of
OkHttp/Retrofit by default. You also have an option to [customize it or
plug in any other HTTP
client](https://docs.langchain4j.dev/tutorials/customizable-http-client).
4. `apiKey` is now optional for all `OpenAi*Model`s
5. `OpenAi*Model`s can now throw
`dev.langchain4j.exception.HttpException` instead of
`dev.ai4j.openai4j.OpenAiHttpException`
6. The default connect timeout is now 15 seconds instead of 60 for all
`OpenAi*Model`s. The default read timeout stays the same (60 seconds).
7. To continue using the "demo" key, you now need to specify the
`baseUrl` explicitly:
```java
OpenAiChatModel model = OpenAiChatModel.builder()
.baseUrl("http://langchain4j.dev/demo/openai/v1")
.apiKey("demo")
.build()
```
8. If you are using `Proxy`, now you need to configure it directly on
the HTTP client of your choice. For example, when using JDK's
`HttpClient`:
```java
HttpClient.Builder httpClientBuilder = HttpClient.newBuilder()
.proxy(ProxySelector.of(new InetSocketAddress("XXX.XXX.XXX.XXX", 1234)));
OpenAiChatModel model = OpenAiChatModel.builder()
.httpClientBuilder(JdkHttpClient.builder().httpClientBuilder(httpClientBuilder))
.apiKey(System.getenv("OPENAI_API_KEY"))
.modelName("gpt-4o-mini")
.build();
```
This also means that all `langchain4j.open-ai.*-model.proxy.*` Spring
Boot properties are not working any more.
9. `OpenAiEmbeddingModel`: removed default `modelName`
(`TEXT_EMBEDDING_ADA_002`), please set it explicitly now
10. `OpenAiImageModel`: removed `withPersisting` and `persistTo`
properties. Persisting images will not be supported any more.
11. `OpenAiLanguageModel` and `OpenAiStreamingLanguageModel`: removed
default `modelName` (`GPT_3_5_TURBO_INSTRUCT`) and `temperature`
(`0.7`), please set it explicitly now
12. `OpenAiModerationModel`: removed default `modelName`
(`TEXT_MODERATION_LATEST`), please set it explicitly now
13. All the `OpenAi*Model` constructors are now accepting a builder
object instead of all the properties
14. The `langchain4j-local-ai` module is now also using
`java.net.http.HttpClient` instead of OkHttp/Retrofit as it depends on
the `langchain4j-open-ai` module

<blockquote>
<h1>Moved to <a
href="https://github.com/pillarjs/path-to-regexp/releases">GitHub
Releases</a></h1>
<h2>3.0.0 / 2019-01-13</h2>
<ul>
<li>Always use prefix character as delimiter token, allowing any
character to be a delimiter (e.g.
<code>/:att1-:att2-:att3-:att4-:att5</code>)</li>
<li>Remove <code>partial</code> support, prefer escaping the prefix
delimiter explicitly (e.g.
<code>\\/(apple-)?icon-:res(\\d+).png</code>)</li>
</ul>
<h2>2.4.0 / 2018-08-26</h2>
<ul>
<li>Support <code>start</code> option to disable anchoring from
beginning of the string</li>
</ul>
<h2>2.3.0 / 2018-08-20</h2>
<ul>
<li>Use <code>delimiter</code> when processing repeated matching groups
(e.g. <code>foo/bar</code> has no prefix, but has a delimiter)</li>
</ul>
<h2>2.2.1 / 2018-04-24</h2>
<ul>
<li>Allow empty string with <code>end: false</code> to match both
relative and absolute paths</li>
</ul>
<h2>2.2.0 / 2018-03-06</h2>
<ul>
<li>Pass <code>token</code> as second argument to <code>encode</code>
option (e.g. <code>encode(value, token)</code>)</li>
</ul>
<h2>2.1.0 / 2017-10-20</h2>
<ul>
<li>Handle non-ending paths where the final character is a delimiter
<ul>
<li>E.g. <code>/foo/</code> before required either <code>/foo/</code> or
<code>/foo//</code> to match in non-ending mode</li>
</ul>
</li>
</ul>
<h2>2.0.0 / 2017-08-23</h2>
<ul>
<li>New option! Ability to set <code>endsWith</code> to match paths like
<code>/test?query=string</code> up to the query string</li>
<li>New option! Set <code>delimiters</code> for specific characters to
be treated as parameter prefixes (e.g. <code>/:test</code>)</li>
<li>Remove <code>isarray</code> dependency</li>
<li>Explicitly handle trailing delimiters instead of trimming them (e.g.
<code>/test/</code> is now treated as <code>/test/</code> instead of
<code>/test</code> when matching)</li>
<li>Remove overloaded <code>keys</code> argument that accepted
<code>options</code></li>
<li>Remove <code>keys</code> list attached to the <code>RegExp</code>
output</li>
<li>Remove asterisk functionality (it's a real pain to properly
encode)</li>
<li>Change <code>tokensToFunction</code> (e.g. <code>compile</code>) to
accept an <code>encode</code> function for pretty encoding (e.g. pass
your own implementation)</li>
</ul>
<h2>1.7.0 / 2016-11-08</h2>
<ul>
<li>Allow a <code>delimiter</code> option to be passed in with
<code>tokensToRegExp</code> which will be used for
"non-ending" token match situations</li>
</ul>
<h2>1.6.0 / 2016-10-03</h2>
<ul>
<li>Populate <code>RegExp.keys</code> when using the
<code>tokensToRegExp</code> method (making it consistent with the main
export)</li>
<li>Allow a <code>delimiter</code> option to be passed in with
<code>parse</code></li>
<li>Updated TypeScript definition with <code>Keys</code> and
<code>Options</code> updated</li>
</ul>
<h2>1.5.3 / 2016-06-15</h2>

## Issue
Closes#1789Closes#2233
## Change
This PR add support to Bedrock Converse API which enable to use any of
text genAI models in AWS Bedrock catalog (including Nova models)
A new BedrockChatModel is added in the converse package.
- Tool use is implemented
- Image content and PDF content is implemented

This PR follow the PR #2132. I proposed my help to @herbert-beckman on
#2132 , he gives a thumbs up so I started working on it. I opened a PR
on his (https://github.com/herbert-beckman/langchain4j/pull/1) but I
never had any reply since, so, as I can't push on the #2132 here I am
opening a new PR.
## Change
This PR adds a new MetadataFilters that allows filtering metadata values
by checking whether they contain or not contain a given string.
Whilst this is less powerful than #2342, it is easier to implement in
embedding stores, this PR implements the `ContainsString` filter for the
following embedding stores:
- Milvus
- PgVector
- Qdrant
I tried to implement it for Chroma as well, but didn't find a way in the
Chroma docs to do so.

## Change
- Ensured that O1 model series is supported
- Updated `OpenAiChatModelName` with all the latest models
## Breaking Changes
Since O1 does not support the `temperature` parameter, it is a good
occasion to finally remove the default vaue of the `temperature`
parameter from `OpenAiChatModel` and `OpenAiStreamingChatModel`.
It is also a good time to finally remove the default value of the
`modelName` parameter.
Please set those values explicitly now:
```java
OpenAiChatModel model = OpenAiChatModel.builder()
.apiKey(System.getenv("OPENAI_API_KEY"))
.defaultRequestParameters(ChatRequestParameters.builder()
.modelName("gpt-4o-mini")
.temperature(0.7)
.build())
.build();
```

https://github.com/langchain4j/langchain4j-spring/pull/103
## Issue
Closes#2397
## Motivation
Currently there are a few problems with existing observability support
for chat models:
- not all models support it (see "Observability" column
[here](https://docs.langchain4j.dev/integrations/language-models/))
- the code to implement it is duplicated in each `ChatLanguageModel`
implementation
- there are redundant `ChatModelRequest` and `ChatModelResponse` types
- there is no way to propagate LLM-provider-specific chat request
parameters and chat response metadata
## Change
- centralised all the logic related to observability/listeners in
`ChatLanguageModel` and `StreamingChatLanguageModel`
- deprecated `ChatModelRequest` and `ChatModelResponse` in favour of
`ChatRequest` and `ChatResponse` in `ChatModelRequestContext`,
`ChatModelResponseContext` and `ChatModelErrorContext`
- migrated OpenAI integration (as a pilot) to inherit observability
logic from `ChatLanguageModel` and `StreamingChatLanguageModel`
## Breaking Changes
1. `OpenAiStreamingChatModel`: in case of errors that happen in the
middle of streaming, partial response (what was streamed before the
error occured) is not propagated into the `ChatModelListener.onError()`
any more in order to simplify the design and implementation. Please
reach out if you have any concerns about it.
2. `OpenAiChatModel` and `OpenAiStreamingChatModel`: if the
`maxCompletionTokens` property is set, it's value is now not propagated
into the `ChatModelListener` via `ChatModelRequest.maxTokens()`.
`ChatModelRequest.maxTokens()` will now return only the value of the
`maxTokens` parameter set on the `OpenAiChatModel` or
`OpenAiStreamingChatModel`.
Now you can get the value of the `maxCompletionTokens` parameter like
this:
```java
ChatModelListener listener = new ChatModelListener() {
@Override
public void onRequest(ChatModelRequestContext requestContext) {
ChatRequestParameters parameters = requestContext.chatRequest().parameters();
if (parameters instanceof OpenAiChatRequestParameters openAiParameters) {
Integer maxCompletionTokens = openAiParameters.maxCompletionTokens();
}
}
};
```
## Next Steps (next PRs)
- Migrate all existing `(Streaming)ChatLanguageModel` implementations
from their own (duplicated) observability functionality to inherit it
from `(Streaming)ChatLanguageModel`

## Issue
Node version requirement (20+) is not well documented. `npm audit`
detected 3 vulnerabilities.
## Change
Run `npm audit fix & npm up`
- Updated the Node.js version requirement to 20 in package.json and
introduced a .nvmrc file for Node Version Manager compatibility. Added
instructions in the README for using nvm to manage Node versions.
- Updated `node` version requirement to >=20.0 and updated several
package versions to their latest releases. Removed unused
`fast-url-parser` and `punycode` dependencies from the
`package-lock.json` to clean up the project.
- Update dependencies in package-lock.json for Algolia packages
- Upgraded various Algolia-related dependencies to their respective
latest versions. This includes packages like
`@algolia/autocomplete-core`, `@algolia/client-common`, and several
others to ensure compatibility and new feature integration.
- Now npm audit fix found 0 vulnerabilities

## Change
While using the OpenAI demo API key as described in the documentation
[here](https://docs.langchain4j.dev/integrations/language-models/open-ai),
I encountered two unexpected errors. Consequently, I've updated the
documentation.
> dev.ai4j.openai4j.OpenAiHttpException: Maximum number of tokens per
request for demonstration purposes is 5000. If you wish to use more,
please use your own OpenAI API key.
> dev.ai4j.openai4j.OpenAiHttpException: Only gpt-4o-mini model is
available for demonstration purposes. If you wish to use another model,
please use your own OpenAI API key.

## Issue
Fixes#1747
## Change
Fixed this bug for Milvus and Chroma.
Did not manage to fix it for Pinecone because Pinecone can store
`Integer`/`Long` only as `Double`. We could theoretically store them as
`String`s, but then metadata filtering for `Integer`/`Long` values will
not work. For now I've left the comment in the `PineconeEmbeddingStore`
Javadoc and Pinecone documentation about the bug and possible
workaround.

## Issue
Closes#896Fixes#1480Fixes#1881Fixes#1858Fixes#1865
## Context
Schema for tool parameters in the low-level API (`ChatLanguageModel` +
`ToolSpecification`) is currently specified using `ToolParameters` and
`JsonSchemaProperty` classes. This API works fine for simple cases, but
it does not work well for more complicated cases (e.g., when nested
objects or collections or recursion is required).
Moreover, [Structured
Outputs](https://github.com/langchain4j/langchain4j/pull/1590) feature
is using another API and a lot of logic between tools and structured
outputs is duplicated and out of sync.
## Change
`ToolParameters` and `JsonSchemaProperty` classes are now deprecated in
favour of new `JsonSchemaElement` API (which is used for Structured
Outputs as well). Most of the logic between this 2 features is now
unified.
`JsonSchemaElement` represents a schema for a JSON element. It can be of
such types:
- `JsonArraySchema`
- `JsonBooleanSchema`
- `JsonEnumSchema`
- `JsonIntegerSchema`
- `JsonNumberSchema`
- `JsonObjectSchema`
- `JsonReferenceSchema`
- `JsonStringSchema`
All model providers that support tools (see the list below) were updated
to support the new API. Old API is still supported for backward
compatibility, but will be removed in the future.
`ToolSpecifications` helper class now generates `ToolSpecification`s
using the new API only.
Example of the new API:
```java
ToolSpecification.builder()
.name("weather")
.description("Returns the current weather in the specified city")
.parameters(JsonObjectSchema.builder()
.addStringProperty("city", s -> s.description("The name of the city, e.g., Munich"))
.addEnumProperty("units", TemperatureUnit.class)
.required("city") // the required properties should be specified explicitly
.build())
.build();
```
`JsonObjectSchema` builder has some helper methods to make it easier to
add properties (e.g., `addProperty`, `addStringProperty`,
`addIntegerProperty`, etc.), but properties can also be specified using
a map:
```java
ToolSpecification.builder()
.name("weather")
.description("Returns the current weather in the specified city")
.parameters(JsonObjectSchema.builder()
.properties(Map.of(
"city", JsonStringSchema.builder().description("The name of the city, e.g., Munich").build(),
"units", JsonEnumSchema.builder().enumValues("CELSIUS", "FAHRENHEIT").build()
))
.required("city") // the required properties should be specified explicitly
.build())
.build();
```

### Additional Changes
Several bugs have been fixed along the way (see the list of Github
issues on the top).
### Breaking changes
- `ToolSpecification.parameters()` method has been renamed into
`toolParameters()`
### Potentially breaking changes
- `ToolSpecifications` helper class now generates `ToolSpecification`s
with parameters defined using the new API (`JsonObjectSchema`) instead
of the old API (`ToolParameters`).
- If `@Tool` does not have a description (`value` annotation attribute),
`ToolSpecifications` will return `ToolSpecification` with `description()
== null`

## Change
In addition to `application/json`, Gemini also supports `text/x.enum` as
a structured output format, which is great for classification.
This PR covers both Google Vertex AI Gemini and Google AI Gemini models.
A minor internal change to create the `GeminiService` at construction
time rather than on each request.
+ Observability (ChatLanguageModel) for Google AI Gemini

## Change
Use awaitility in `EmbeddingStoreIT`
## General checklist
- [X] There are no breaking changes
- [X] I have added unit and integration tests for my change
- [x] I have manually run all the unit and integration tests in the
module I have added/changed, and they are all green
- [x] I have manually run all the unit and integration tests in the
[core]
## Issue
Closes#1132
## Change
Added SearchApi as a WebSearchEngine that also can be used as a tool.
Currently using Google Search as default engine. It also allows for new
engines to be implemented using the SearchApiRequestResponseHandler
interface, and adding it to the SearchApiEngine enum so the user can
choose which one to use.

@algora-pbc /claim #1132
The current implementation uses a slow function score query which is
known to be slow because you have to iterate over all the hits to
compute the score.
Elasticsearch in the recent versions, now also allow using knn search.
This PR now allows to change the configuration:
```java
// Use the Knn implementation
ElasticsearchEmbeddingStore store = ElasticsearchEmbeddingStore.builder()
.configuration(ElasticsearchConfigurationKnn.builder().build())
.restClient(restClient)
.build();
// Note that this configuration is optional as it's the default behavior. So this code is equivalent:
ElasticsearchEmbeddingStore store = ElasticsearchEmbeddingStore.builder()
.restClient(restClient)
.build();
// Use the Scripting implementation (slower)
ElasticsearchEmbeddingStore store = ElasticsearchEmbeddingStore.builder()
.configuration(ElasticsearchConfigurationScript.builder().build())
.restClient(restClient)
.build();
```
In more details, this is what this PR is bringing:
* Add a `configuration` new option in the builder. This helps to choose
the implementation to use. It could be
`ElasticsearchConfigurationScript` (the behavior before this change) or
`ElasticsearchConfigurationKnn` for the new Knn implementation
* The Knn implementation (`ElasticsearchConfigurationKnn`) is now the
default implementation
* Removes the `dimension` parameter as Elasticsearch can guess
automatically this value based on the first document indexed. And
anyway, it's better to let the user create an index template or the
index mapping he wants.
* Modify the IT. In which case if a local instance of Elasticsearch is
yet running on https://localhost:9200, we will use it by default and
start Testcontainers only if needed.
* Make Elasticsearch container secured (which is closer to production
use case)
* We now use the `elastic.version` `pom.xml` property to launch the
right Elasticsearch TestContainer.
* Replaced the `removeAll()` implementation from a `DeleteByQuery(match
all query)` to a Delete index API call which is always the recommended
way to remove all documents. Note that this does not recreate an index.
* `ElasticsearchEmbeddingStoreRemoveIT` now extends the common removal
test class `EmbeddingStoreWithRemovalIT`. But we need to implement in
the future a `EmbeddingStoreWithRemovalIT.wait_for_ready()` method to
allow even more common tests.
* Add more logs in implementation and tests
