When does this happen?
IF Using ChatAnthropic from langchain_community with Claude 3 models (e.g., claude-3-opus-20240229) triggers a 400 error: 'model not supported on this API. Please use the Messages API.'
How others solved it
THEN Upgrade to the langchain-anthropic package and import ChatAnthropic from langchain_anthropic instead of langchain_community. This ensures compatibility with the Messages API required for Claude 3 models. Run: pip install -U langchain-anthropic, then import from langchain_anthropic import ChatAnthropic. The streaming parameter is supported in this version.
pip install -U langchain-anthropic from langchain_anthropic import ChatAnthropic llm = ChatAnthropic(temperature=0.5, max_tokens=1000, model='claude-3-opus-20240229', streaming=True)
