Hi:) You can adjust the relevant settings in the model_backend.py, including modeltype, your API_KEY, etc.

If you want to use Ollama in local setup, you can follow my steps:

1. Set environment variables:

   export OPENAI_API_KEY=ollama  # any value
   export BASE_URL=http://localhost:11434/v1  # your Ollama API server

2. Replace model parameter to your model in Ollama: https://github.com/OpenBMB/ChatDev/blob/bbb145048ef1a1be727cd4f176b8bafe1a5f15db/camel/model_backend.py#L100 Example:

   response = client.chat.completions.create(*args, **kwargs, model="gemma:2b-instruct",
                                             **self.model_config_dict)

3. Run:

   python3 run.py --task "[description_of_your_idea]" --name "[project_name]"
