AI NewsClaude Opus 5, released July 24, 2026, is Anthropic's new default model: near-Fable 5 capability at $5/$25 per million tokens (half Fable 5's price, flat vs Opus 4.8). It leads on Anthropic's own runs of Frontier-Bench, OSWorld 2.0, AutomationBench, ARC-AGI-3 and GDPval, but loses on DeepSWE, HLE, a legal benchmark and HealthBench. It posts Anthropic's lowest misalignment score (2.30), ships with no default data retention, and adds beta tool-swapping and safety-filter model routing.

Its pitch is matching Anthropic's Claude Mythos on capability while costing far less. Microsoft has not officially confirmed details, so the news should be treated as a credible report pending benchmarks.
