Notes
Released July 24, 2026 at UNCHANGED Opus pricing ($5/$25 per MTok input/output) but with substantially higher capability. Anthropic positions it as "approaching Fable 5 intelligence at half the price." 1M-token context window. Benchmarks: IMO 2026 42/42 gold-medal performance (above the 29/42 cutoff), ARC-AGI-3 30.16% at high effort (~4x previous leaderboard best), Humanity's Last Exam 56.3% no tools / 64.7% with tools. More than doubles Opus 4.8 on agentic terminal coding benchmarks. Lowest misalignment score Anthropic has ever measured. This release effectively deprecates Opus 4.8 (same price, worse) and puts pricing pressure on Fable 5 ($10/$50 for marginal capability gain). Signals Anthropic competing on capability, not extracting rents — likely a competitive response to GPT-5.6 Sol, Kimi K3, and Grok 4.5 crowding the frontier.
