 LangServe provides support for Pydantic 2 with some limitations.

 1. OpenAPI docs will not be generated for invoke/batch/stream/stream_log when using
-   Pydantic V2. Fast API does not support [mixing pydantic v1 and v2 namespaces]. To fix this, use `pip install pydantic==1.10.17`.
+   Pydantic V2 and LangServe <= 0.2.0. Fast API does not support [mixing pydantic v1 and v2 namespaces]. To fix this, please upgrade langserve to 0.3 or downgrade pydantic to pydantic 1 `pip install pydantic==1.10.17`.
 2. LangChain uses the v1 namespace in Pydantic v2. Please read
   the [following guidelines to ensure compatibility with LangChain](https://github.com/langchain-ai/langchain/discussions/9337)
