Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

When setting the global default model to GLM-4, the suggested interface returns a 400 error when calling large models, because the GLM-4 large model does not support setting the temperature parameter to 0.0

The problematic code is in dify\api\core\llm_generator\llm_generator.py line:83

            response = model_instance.invoke_llm(
                prompt_messages=prompt_messages,
                model_parameters={
                    "max_tokens": 256,
                    "temperature": 0
                },
                stream=False
            )

It is recommended to set the default temperature to 0.1.

✔️ Expected Behavior

Correct suggestions returned

❌ Actual Behavior

The exception in the large model of the interface was caught, and an empty suggestion was returned.
