ollama[patch]: fix model validation, ensure per-call reasoning can be set, tests ( #31927 )
...
* update model validation due to change in [Ollama
client](https://github.com/ollama/ollama ) - ensure you are running the
latest version (0.9.6) to use `validate_model_on_init`

class-level setting
* tests

ollama: thinking, tool streaming, docs, tests ( #31772 )
...
* New `reasoning` (bool) param to support toggling [Ollama
thinking](https://ollama.com/blog/thinking ) (#31573 , #31700 ). If
`reasoning=True`, Ollama's `thinking` content will be placed in the
model responses' `additional_kwargs.reasoning_content`.
* Supported by:
* ChatOllama (class level, invocation level TODO)
* OllamaLLM (TODO)
* Added tests to ensure streaming tool calls is successful (#29129 )
* Refactored tests that relied on `extract_reasoning()`
* Myriad docs additions and consistency/typo fixes
* Improved type safety in some spots
Closes #29129
Addresses #31573 and #31700
Supersedes #31701

langchain-ollama (partners) / langchain-core: allow passing ChatMessages to Ollama (including arbitrary roles) ( #30411 )
...
Replacement for PR #30191 (@ccurme)
**Description**: currently, ChatOllama [will raise a value error if a
ChatMessage is passed to
it](https://github.com/langchain-ai/langchain/blob/master/libs/partners/ollama/langchain_ollama/chat_models.py#L514 ),
as described
https://github.com/langchain-ai/langchain/pull/30147#issuecomment-2708932481 .
Furthermore, ollama-python is removing the limitations on valid roles
that can be passed through chat messages to a model in ollama -
https://github.com/ollama/ollama-python/pull/462#event-16917810634 .
This PR removes the role limitations imposed by langchain and enables
passing langchain ChatMessages with arbitrary 'role' values through the
langchain ChatOllama class to the underlying ollama-python Client.
As this PR relies on [merged but unreleased functionality in
ollama-python](
https://github.com/ollama/ollama-python/pull/462#event-16917810634 ), I
have temporarily pointed the ollama package source to the main branch of
the ollama-python github repo.
Format, lint, and tests of new functionality passing. Need to resolve
issue with recently added ChatOllama tests. (Now resolved)
**Issue**: resolves #30122 (related to ollama issue
https://github.com/ollama/ollama/issues/8955 )
**Dependencies**: no new dependencies
