Let OpenRouter Keys Work with More Models

OpenRouter provides access to many models that are, in T3.chat, only available behind their respective provider’s keys (like Anthropic & OpenAI). I would personally prefer to use my OpenRouter key for them.

The limitation is that, currently in T3.chat, the BYOK feature for models like GPT-5.2 only permits you to use the respective companies API (for the case of GPT-5.2, OpenAI’s platform API).
