Mason Daugherty 63cc1f4e7d docs: refresh README installation and resources (#38119 )

README installation examples now use `uv add` consistently, matching the
repo's `uv`-based Python workflow. The top-level README also gets a
cleaner quickstart and resource section with current links for docs,
community, learning, and contribution guidance.

## Changes
- Replaced `pip install` snippets with `uv add` across package quick
install docs, including the Hugging Face extras and
`sentence-transformers` upgrade examples.
- Updated the top-level quickstart to show only `uv add langchain` and
refreshed the example model to `openai:gpt-5.5`.
- Pointed the LangGraph orchestration link at the LangGraph GitHub
repository.
- Consolidated top-level documentation and additional-resource links
under a single `Resources` section covering docs, ecosystem overview,
API reference, discussions, Academy, contributing, and the Code of
Conduct.
- Added LangChain Academy and Code of Conduct links to package README
resource sections.

🦜🪪 langchain-model-profiles

Warning

This package is currently in development and the API is subject to change.

CLI tool for updating model profile data in LangChain integration packages.

Quick Install

uv add langchain-model-profiles

🤔 What is this?

langchain-model-profiles is a CLI tool for fetching and updating model capability data from models.dev for use in LangChain integration packages.

LangChain chat models expose a .profile field that provides programmatic access to model capabilities such as context window sizes, supported modalities, tool calling, structured output, and more. This CLI tool helps maintainers keep that data up-to-date.

Data sources

This package is built on top of the excellent work by the models.dev project, an open source initiative that provides model capability data.

LangChain model profiles augment the data from models.dev with some additional fields. We intend to keep this aligned with the upstream project as it evolves.

📖 Documentation

For full documentation, see the API reference. For conceptual guides, tutorials, and examples on using LangChain, see the LangChain Docs. You can also chat with the docs using Chat LangChain.

Usage

Update model profile data for a specific provider:

langchain-profiles refresh --provider anthropic --data-dir ./langchain_anthropic/data

This downloads the latest model data from models.dev, merges it with any augmentations defined in profile_augmentations.toml, and generates a profiles.py file.
