`libs/community/langchain_community/callbacks/bedrock_anthropic_callback.py`
file to add a new model version to the list of supported models.
Updates to supported models:
* Added support for the `anthropic.claude-3-7-sonnet-20250219-v1:0`
model with a rate of `0.003` for 1000 input tokens.
* Added support for the `anthropic.claude-3-7-sonnet-20250219-v1:0`
model with a rate of `0.015` for 1000 output tokens.

### PR Title:
**community: add latest OpenAI models pricing**
### Description:
This PR updates the OpenAI model cost calculation mapping by adding the
latest OpenAI models, **o1 (non-preview)** and **o3-mini**, based on the
pricing listed on the [OpenAI pricing
page](https://platform.openai.com/docs/pricing).
### Changes:
- Added pricing for `o1`, `o1-2024-12-17`, `o1-cached`, and
`o1-2024-12-17-cached` for input tokens.
- Added pricing for `o1-completion` and `o1-2024-12-17-completion` for
output tokens.
- Added pricing for `o3-mini`, `o3-mini-2025-01-31`, `o3-mini-cached`,
and `o3-mini-2025-01-31-cached` for input tokens.
- Added pricing for `o3-mini-completion` and
`o3-mini-2025-01-31-completion` for output tokens.
### Issue:
N/A
### Dependencies:
None
### Testing & Validation:
- No functional changes outside of updating the cost mapping.
- No tests were added or modified.
### Description
- Since there is no cost per 1k input tokens for a fine-tuned cached
version of `gpt-4o-mini-2024-07-18` is not available when using the
`OpenAICallbackHandler`, it raises an error when trying to make calls
with such model.
- To add the price in the `MODEL_COST_PER_1K_TOKENS` dictionary
cc. @efriis
In the previous commit, the cached model key for this model was omitted.
When using the "gpt-4o-2024-11-20" model, the token count in the
callback appeared as 0, and the cost was recorded as 0.
We add model and cost information so that the token count and cost can
be displayed for the respective model.
- The message before modification is as follows.
```
Tokens Used: 0
Prompt Tokens: 0
Prompt Tokens Cached: 0
Completion Tokens: 0
Reasoning Tokens: 0
Successful Requests: 0
Total Cost (USD): $0.0
```
- The message after modification is as follows.
```
Tokens Used: 3783
Prompt Tokens: 3625
Prompt Tokens Cached: 2560
Completion Tokens: 158
Reasoning Tokens: 0
Successful Requests: 1
Total Cost (USD): $0.010642500000000001

This change modifies the token cost calculation logic to support
cross-region inference profile IDs for Anthropic Claude models. Instead
of explicitly listing all regional variants of new inference profile IDs
in the cost dictionaries, the code now extracts a base model ID from the
input model ID (or inference profile ID), making it more maintainable
and automatically supporting new regional variants.
These inference profile IDs follow the format:
`<region>.<vendor>.<model-name>` (e.g.,
`us.anthropic.claude-3-haiku-xxx`, `eu.anthropic.claude-3-sonnet-xxx`).
Cross-region inference profiles are system-defined identifiers that
enable distributing model inference requests across multiple AWS
regions. They help manage unplanned traffic bursts and enhance
resilience during peak demands without additional routing costs.

This PR adds annotations in comunity package.
Annotations are only strictly needed in subclasses of BaseModel for
pydantic 2 compatibility.
This PR adds some unnecessary annotations, but they're not bad to have
regardless for documentation pages.

They cause `poetry lock` to take a ton of time, and `uv pip install` can
resolve the constraints from these toml files in trivial time
(addressing problem with #19153)
This allows us to properly upgrade lockfile dependencies moving forward,
which revealed some issues that were either fixed or type-ignored (see
file comments)
Hey, I'm Sasha. The SDK engineer from [Comet](https://comet.com).
This PR updates the CometTracer class.
Added metadata to CometTracerr. From now on, both chains and spans will
send it.
UpTrain has a new dashboard now that makes it easier to view projects
and evaluations. Using this requires specifying both project_name and
evaluation_name when performing evaluations. I have updated the code to
support it.
## Summary
I ran `ruff check --extend-select RUF100 -n` to identify `# noqa`
comments that weren't having any effect in Ruff, and then `ruff check
--extend-select RUF100 -n --fix` on select files to remove all of the
unnecessary `# noqa: F401` violations. It's possible that these were
needed at some point in the past, but they're not necessary in Ruff
v0.1.15 (used by LangChain) or in the latest release.

Hi! My name is Alex, I'm an SDK engineer from
[Comet](https://www.comet.com/site/)
This PR updates the `CometTracer` class.
Fixed an issue when `CometTracer` failed while logging the data to Comet
because this data is not JSON-encodable.
The problem was in some of the `Run` attributes that could contain
non-default types inside, now these attributes are taken not from the
run instance, but from the `run.dict()` return value.
- **Description:**
This PR adds a callback handler for UpTrain. It performs evaluations in
the RAG pipeline to check the quality of retrieved documents, generated
queries and responses.
- **Dependencies:**
- The UpTrainCallbackHandler requires the uptrain package

This PR updates the on_tool_end handlers to return the raw output from the tool instead of casting it to a string.
This is technically a breaking change, though it's impact is expected to be somewhat minimal. It will fix behavior in `astream_events` as well.
Fixes the following issue #18760 raised by @eyurtsev
