Opus 5 outperforms Fable 5 on most benchmarks including knowledge work (GDPval-AA v2: 1861 vs 1747), agentic terminal coding, computer use, and business workflows (AutomationBench). Fable 5 retains leads in legal benchmarks and DeepSWE agentic coding. Opus 5 is now the default model for Claude Max subscribers and the best available for Claude Pro users. It features a fast mode (2.5x faster, 2x cost), improved safety classifiers scoped more narrowly than Fable 5's, and new platform features including automatic safety fallbacks and mid-conversation tool changes without cache invalidation. Compared to OpenAI's GPT-5.6 Sol, Opus 5 leads on most benchmarks except DeepSWE agentic coding. ## Full article daily.dev links to this article rather than hosting it.
