What issue do you have?

I am trying to use OpenRouter as my AI provider, but I don't know if this is possible yet.

I know I'm trying to use Claude with an OpenAI-compatible key, but I think this is the type of key OpenRouter provides.

I'm attaching a screenshot of the tried setup, with error code "404: Not found".

Try maybe just https://openrouter.ai/api/v1

Not sure about the model, but their doc gives for example openai/o4-mini so maybe try with this first

That did it, thank you Laurent!
