Steps to reproduce

在定义Agent的时候，配置工具后，使用gpt-4o和gpt-4o-mini可以正确调用工具，但是使用其他模型，如 deepseek-coder、doubao-lite-128k、moonshot-v1-128k 都无法正确调用工具。这个是模型的问题还是平台的问题？

@kenneth-bro Hello there! I'm here to help you with any bugs, questions, or contributions while you wait for a human maintainer. Let's tackle this together!

The issue with tools not being invoked correctly when using models like deepseek-coder, doubao-lite-128k, and moonshot-v1-128k in Dify version 0.7.0 (Docker) is a problem with the models. Specifically, the doubao-lite-128k model supports tool invocation, while the moonshot-v1-128k model does not have the ModelFeature.TOOL_CALL feature, indicating it does not support tool invocation ^[1]^[2].

To ensure proper tool invocation, you need to verify the configurations and credentials for each model. For example, the moonshot-v1-128k model requires the function_calling_type to be set to tool_call in the credentials:

credentials = {
    'api_key': 'your_api_key',
    'function_calling_type': 'tool_call',
    'context_size': 4096,
    'max_tokens': 512,
    # other necessary credentials
}

Ensure that your credentials dictionary includes 'function_calling_type': 'tool_call' when invoking the model ^[3].
