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.
