Anthropic released Claude Opus 4.8 yesterday, and from the announcement it looks like a solid upgrade over 4.7. Here s what stood out to me:
Better judgment on agentic tasks early testers say it catches its own mistakes, pushes back on bad plans, and flags uncertainties instead of bulldozing through
~4x less likely to let code flaws pass unremarked compared to Opus 4.7
Dynamic Workflows in Claude Code can now orchestrate hundreds of parallel subagents for codebase-scale migrations
Effort control you can now choose how hard the model thinks on each response (from fast/light to max effort)
Fast mode is 3x cheaper than it was for previous models
Same pricing as Opus 4.7: $5/M input, $25/M output
