Error 404 when using Gemini API with OpenAI-compatible command

[amanshaw4511]

I am attempting to use the Gemini API with OpenAI-compatible commands, but I am encountering a 404 error. Below are the details of my setup and the command I am using.

$ go run . --provider openai --model gemini-2.0-flash --url https://generativelanguage.googleapis.com/v1beta/openai/ --key <KEY> asdf
Request: https://generativelanguage.googleapis.com/v1beta/openai/ {
                "frequency_penalty": 0,
                "messages": [

                        {
                                "content": "asdf",
                                "role": "user"
                        }
                ],
                "model": "gemini-2.0-flash",
                "presence_penalty": 0,
                "stream": true,
                "temperature": 0.5,
                "top_p": 0.5
        }

Some error has occurred. Statuscode: 404

Does it support gemini?

You need to enter the full url to the api, which in this case is https://generativelanguage.googleapis.com/v1beta/openai/chat/completions

[aandrew-me]

You may need to remove some fields from the openai file like frequency_penalty

[amanshaw4511]

Okay @aandrew-me . Shall I add gemini as another provider?

[amanshaw4511]

Also what do you think about LiteLLM. There is similar package for go gollm.

Sure

Also what do you think about LiteLLM. There is similar package for go gollm.

I don't want the app to depend on third party libraries for this purpose

[aandrew-me]

Gemini provider will be available in next update

@amanshaw4511
Should be full url: https://generativelanguage.googleapis.com/v1beta/openai/chat/completions

1. completions
2. You should not try to open the url in the browser
