A 680,000-LINE MIGRATION THAT WOULD HAVE TAKEN A TEAM WEEKS CLAUDE OPUS 5.5 FINISHED IT IN UNDER A DAY Anthropic shipped Opus 5.5 today frontier results, 40% cheaper than Opus 5 it leads on agentic coding, computer use and knowledge work: > Terminal-Bench 4.0 - 66.4% vs 52.3% for Opus 5 > GDPval-AA v2.1 - 1846 vs 1735 for Fable 5.1 > cache reads $0.20 per million, 60% cheaper > output comes out 30% faster but the story I keep coming back to is the audit one tester fixed a 200,000-line codebase in under three hours Opus 5 needed over 20 hours and 2.5x the tokens on the same job seventeen hours handed back to someone, on one task Deloitte ran it at its lowest effort setting and it caught 72% of known bugs Opus 5 at high effort caught 56% the cheap setting now beats the expensive one Opus 5.5 is live everywhere today. $4 in, $20 out I've stopped being surprised by the benchmarks. the price drop is what I'm still sitting with
