Claude Opus 5 Deep Dive — Anthropic's July 24, 2026 Release Keeps $5/$25 While Frontier-Bench Goes 18.7% → 44.4% 1M Context, 128K Output (300K via Batch), the New xhigh Effort Level, OSWorld 2.0 at 70.57% and SWE-bench Verified at 96.0% Opus 4.8 Goes Legacy, Opus 4.1 Retires August 5, 2026 — and thinking: disabled with xhigh Now Returns a 400
Anthropic released Claude Opus 5 on July 24, 2026. Pricing holds at $5 / $25 per M tokens, unchanged from Opus 4.8, while Frontier-Bench v0.1 jumps 18.7% → 44.4% (xhigh), OSWorld 2.0 goes 55.7% → 70.57%, and ARC-AGI-3 goes 1.52% → 30.16%. It ships a 1M context window (default = maximum) with 128K max output (300K via the Batches API), and drops the minimum cacheable prompt to 512 tokens. The new xhigh effort level — above high, below max — targets agentic runs of 30+ minutes and actually beats max (43.3%) on Frontier-Bench. Breaking changes: thinking cannot be disabled at xhigh or max (the API returns a 400), Opus 4.8 is now legacy, and Opus 4.1 retires August 5, 2026. SWE-bench Verified hits 96.0%, but SWE-bench Pro at 79.2% stays just short of Fable 5's 80.0% — Opus 5 replaces Opus 4.8, not Fable 5.
