Steps to reproduce

I install Replicate plugin, then I add some models. I can add some models like Llama 8B, Llama 70B, but some other models can not be added. The error is "Model {model_name}:{version} is not a Text Generation model."

I read the source code of Replicate plugin (https://github.com/langgenius/dify-official-plugins/blob/306ffadf9c7b227f63cc9587e439c0c4c231a72b/models/replicate/models/llm/llm.py) and realize that this error happen because the code only check some conditions to verify where the model is LLM or not from line 119 to 140:


 def _check_text_generation_model(
        model_info_version, model_name, version, description
    ):
        if "language model" in description.lower():
            return
        if (
            "temperature"
            not in model_info_version.openapi_schema["components"]["schemas"]["Input"][
                "properties"
            ]
            or "top_p"
            not in model_info_version.openapi_schema["components"]["schemas"]["Input"][
                "properties"
            ]
            or "top_k"
            not in model_info_version.openapi_schema["components"]["schemas"]["Input"][
                "properties"
            ]
        ):
            raise CredentialsValidateFailedError(
                f"Model {model_name}:{version} is not a Text Generation model."
            )

The info of an OpenAI model is like

{'url': 'https://replicate.com/openai/gpt-4.1',
 'owner': 'openai',
 'name': 'gpt-4.1',
 'description': "OpenAI's Flagship GPT model for complex tasks."
...
}

=> Error. Please add some rules to this. Thank you.

✔️ Error log

Model {model_name}:{version} is not a Text Generation model.

Hi, @hellpoethero. I'm Dosu, and I'm helping the dify-official-plugins team manage their backlog and am marking this issue as stale.

Issue Summary:

  • You reported that in Dify v1.4.1, the Replicate plugin rejects some valid models with the error "Model {model_name}:{version} is not a Text Generation model."
  • The problem stems from the plugin's limited checks to identify large language models (LLMs), causing false negatives.
  • There have been no further comments or updates on this issue since your report.

Next Steps:

  • Please let me know if this issue is still relevant with the latest version of the dify-official-plugins repository by commenting here.
  • If I don’t hear back within 5 days, I will automatically close this issue.

Thank you for your understanding and contribution!
