Mason Daugherty abd9d4ce31 ci(infra): harden Dependabot version-bound preservation (#37510 )

Dependabot has been stripping upper/lower bounds from internal
`langchain-*` deps in partner `pyproject.toml` files (e.g. #37288
reduced `langchain-core>=1.3.2,<2.0.0` to bare `langchain-core`). Locks
down the config so bumps preserve existing specifiers, and restores the
bounds it already mangled across the monorepo.

## Changes
- Add `versioning-strategy: increase` to every `uv` ecosystem block in
`.github/dependabot.yml` so future bumps move the lower bound in place
instead of rewriting the constraint.
- Ignore workspace-internal packages (`langchain-core`, `langchain`,
`langchain-classic`, `langchain-text-splitters`, `langchain-tests`,
`langchain-model-profiles`) on every `uv` block — these are editable
installs from local paths and their published constraints are
hand-curated for release, not Dependabot's to bump.
- Restore stripped bounds across all `libs/` packages — runtime
`dependencies` and every dep group (`test`, `dev`, `test_integration`,
`typing`, `lint`) — to `>=1.4.0,<2.0.0` for `langchain-core` and
`>=1.0.0,<2.0.0` for the other internal packages.

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

pip install 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.
