No mention of Opus there or here (so far).

Having tried everything I settled on a $100/month Anthropic "Max" plan to use Claude Code. Then I learned how Claude Opus 4 is currently their best but most expensive model for my situation (math code and research). I limited out of a five hour session, switched to their API, and burned $20 in an hour. So I upgraded to $200/month "Max" and haven't hit limits yet.

Models matter. All these stories are like "I met a person who wasn't that smart." Duh!
