Now that I double-check this stop working. it is not even working with non OpenAI models. Even if I disable the usage of the OpenAI key (with modified URL pointing to Openrouter) then trying to use Google models still fails because Cursor is trying to use the custom OpenAI Base URL. That means that if you modified the Base URL then Cursor will always try to use that one, instead of the appropriates for Anthropic, google etc.
