## Note
Please note that [issue ](https://github.com/square/okhttp/issues/8288)
for this was already created in `httpok` repository but it will not be
fixed in 4.x. It's reportedly already tackled in version 5.x.
With that in mind I suggest we apply temporary changes proposed in this
PR. After upgrading to `httpok` 5.x we will be able to remove these.
## Tests
`mvn clean test` passed
## Issue
Closes#1465
## Change
According to
[retrofit](https://github.com/square/retrofit/blob/trunk/retrofit%2Fsrc%2Fmain%2Fjava%2Fretrofit2%2FRetrofit.java#L564)
base urls should always end with `/`.
Added new utility method to ensure that a provided base url always ends
with a `/` and checked existing API classes so that they all start
**without** a `/`.
### Tests
I have added unit test for the new utility method but testing the actual
invocation of the method in the different builder classes is harder. The
existing Ollama test case spins up a temporary web server and I don't
want to replicate this to al lmodules since I suspect build times will
increase a lot etc.
Thoughts?

## Issue
#1080
## Change
Adds a `dimension()` method in the `EmbeddingModel` interface that returns the dimension of the `Embedding`s produced by this `EmbeddingModel`.
If dimension is known (e.g., can be derived from the model name), it is returned. If not known, a "test" string is embedded and the embedding dimension is cached and returned.
