Claude 4.8 Defaults to High Effort, Improved Coding Performance
By
–
4.8 defaults to high effort, which spends about the same tokens as 4.7's default on coding but performs better. For hard problems and long-running async work, switch to xhigh. We've raised Claude Code rate limits to cover the extra tokens.

Claude Opus 4.8 Released: Stronger Coding Model with Benchmarks
By
–
Claude Opus 4.8 is out today. It's our strongest coding model yet: up on SWE-bench Pro (from 64.3 to 69.2) and noticeably more honest about its own work. It tells you when it's unsure and catches its own bugs instead of declaring victory early. Same price as 4.7.
