@Devi1k Hello there! I'm here to assist you with bug fixes, answer questions, and guide you on becoming a contributor. Let's work together to resolve any issues you may have.

The Wenxin ERNIE model currently does not support function calling in Dify. This is why you are encountering the "[wenxin] Bad Request Error, function calling is not supported yet" message when trying to invoke the Google search tool [1][2].

There are plans to support function calling for the Wenxin model in future versions of Dify, as indicated by a placeholder comment in the code [1].

In the meantime, you can use alternative models that support function calling, such as OpenAI, Anthropic, Azure OpenAI, Minimax, Moonshadow, deepseek, Xinference, Zhipu AI, Stepfun, and Baichuan [3][4][5][6].

To configure and use a different model in Dify's studio agent mode that supports function calling, follow these steps:

  1. Add and Configure the Model Provider:

    • Navigate to Settings --> Model Providers to add and configure the LLM you are going to use.
    • Obtain the API key from the model provider's official website before using it in Dify.

  2. Select the Reasoning Model:

    • Navigate to the section where you can select the reasoning model for the Agent Assistant.
    • Choose a model that supports function calling, such as GPT-3.5 or GPT-4.

  3. Configure Agent Settings:

    • Go to the Agent settings.
    • Ensure that the inference mode is set to "Function Calling."

  4. Add Tools (if necessary):

    • In the "Tools" section, add any required tools that the Agent Assistant might need to enhance its capabilities.

  5. Write Prompts:

    • In the 'Instructions' section, write clear prompts for the Agent Assistant.

  6. Debug and Preview:

    • Use the debugging and preview options to test its effectiveness in completing tasks.

  7. Publish the Application:

    • Once satisfied with the configuration and performance, publish the application as a web app [7][8][9].

As you can see, weinxin LLM doesn't support those features.

If you are interested in contributing to this feature, you can open a pull request then.
