/model autocomplete confusion
The model was set using /Model command

Thank you for filing this issue.
The autocomplete for /model is confusing currently, as the whole LiteLLM database gets pulled in and some of those entries do not seem to work. The correct command to switch to Sonnet-3.5 inside aider is
/model claude-3-5-sonnet-20240620
Please try this command and report if this works you (and avoid anthropic.* model names for now)
For completeness sake: I assume you typed /model and then used autocomplete to complete the model name to
/model anthropic.claude-3-5-sonnet-20240620-v1:0
is that correct? (this would explain the strange model name)
I'm going to close this issue for now, but feel free to add a comment here and I will re-open. Or feel free to file a new issue any time.
Edit: I have managed to solve the problem. Even though the documentation of crewAI says that these models are supported, apparently Anthropic API does not support them anymore :D
I've checked Anthropic's documentation:
Reference: https://docs.claude.com/en/docs/about-claude/models/overview
and I've updated my code with the following:
# Set up the Claude Model
llm_claude = LLM(
model="anthropic/claude-haiku-4-5-20251001",
api_key=os.getenv("CLAUDE_API_KEY"),
temperature=0.7,
max_tokens=4096, # Required for Anthropic
)
Problem
I have the same problem, when I try to call Claude models from crewAI:
# Set up the Claude Model
llm_claude = LLM(
model="anthropic/claude-3-5-sonnet-20241022",
api_key=os.getenv("CLAUDE_API_KEY"),
temperature=0.7,
max_tokens=4096, # Required for Anthropic
)
This model is said to be supported by crewAI:
Reference: https://docs.crewai.com/en/concepts/llms#anthropic
and the error that I receive is the following:
