## Our verdict

Opus 4.8 is a clean upgrade at the same list price, agentic coding rises from 64.3% to 69.2% on SWE-Bench Pro, it leads computer use at 84% on Online-Mind2Web, runs autonomously for longer and reports progress more honestly. Fast mode is now 3× cheaper and the minimum cacheable prompt drops to 1,024 tokens. There is no reason to start a new project on 4.7, go straight to 4.8.
