It seems like it's the cheapest way to access Claude Sonnet 4.5, but the model distribution is clearly throttled compared to Claude Sonnet 4.5 on claude.ai.

That being said, I don't know why anyone would want to pay for LLM access anywhere else.

ChatGPT and claude.ai (free) and GitHub Copilot Pro ($100/yr) seem to be the best combination to me at the moment.
