Mason Daugherty faadc1f3ce ci: suppress pytest streaming output in CI (#36092 )

Reduce CI log noise by suppressing pytest's per-test dot/verbose
streaming output. The `_test.yml` workflow now passes `PYTEST_EXTRA=-q`
to `make test`, which overrides the default verbosity with quiet mode —
failures still print in full, but the thousands of `.......` progress
lines are gone. Local `make test` is unaffected since `PYTEST_EXTRA`
defaults empty.

## Changes
- Add `PYTEST_EXTRA ?=` variable to all 21 package Makefiles and inject
it into each `test` target's pytest invocation
- Pass `PYTEST_EXTRA=-q` in `_test.yml` for both the main test step and
the min-version retest step

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.
