What is Claude's Max effort setting?

Max delivers exhaustive reasoning in Claude Code, above the now-capped High tier. Essential for complex code like GPU transpilers or WebRTC—catches bugs High misses.

Did Anthropic notify users about the new Max tier?

No. Added late March 2026, no emails, banners, or CLI alerts. Existing High users got downgraded silently.

Should I switch to Max in Claude Code?

Yes, if doing prod engineering. Audit recent High-generated code—expect bugs. Defaults won't save you.
