Checked other resources

  • I added a very descriptive title to this issue.
  • I searched the LangGraph/LangChain documentation with the integrated search.
  • I used the GitHub search to find a similar question and didn't find it.
  • I am sure that this is a bug in LangGraph/LangChain rather than my code.
  • I am sure this is better as an issue rather than a GitHub discussion, since this is a LangGraph bug and not a design question.

Mention any other details that might be useful
I am trying to use Phi 3 mini 128 instruct with Langgraph for a multi-agent framework where it can route requests accurately. However, Phi 3 is not able to route the queries properly to a specific tool. Can anyone help? Does Phi 3 work with Langgraph, and does it support function calling or tool calling?

If you use Ollama, you can first check https://ollama.com/blog/tool-support to see if the model supports tool_call.
If it doesn't, it won't function properly.
