I think t4 is too old now. 😄

There is an upstream langchain PR yet to be merged. https://github.com/langchain-ai/langchain/pull/12968.

Once that one is merged you can install the patch with `pip install "git+https://github.com/bentoml/langchain.git@chore/migrate-to-new-api#subdirectory=libs/langchain"`

YOu can install langchain from the pip command.

What is the issue you are running into?

Honestly, I'm waiting for Astral (the company that builds Ruff) to build a type checker, haha. Will then use whatever they are cooking up there.

already migrate my whole workflow to uv and rye haha

ye, think of rye as better pdm

ruff is not a type checker, it is a linter. the LSP is just a lint server.

what models are you using?
