Claude Opus 4.7

Anthropic's Claude Opus 4.7, deployed May 2026, stakes its claim as a frontier model with 80.1 SWE-Bench and 1M context window. It deploys RLHF, Chain-of-Thought prompting, and Constitutional AI — Anthropic's signature safety stack. The model powers both Claude Security and Claude Code products, the latter autonomously porting Lightroom CC to Linux. But the competitive landscape is brutal. Opus 4.7 competes with no fewer than six models: GPT-5, GPT-5.3, GPT-4 Turbo, GPT-3.5, Gemini 3 Pro, and its predecessor Opus 4.6. The sharpest threat comes from Cursor's Composer 2, which reportedly matches Opus 4.7 and GPT-5.5 at a fraction of the cost. Anthropic's recent move to deprecate fixed thinking budgets in favor of adaptive mode signals an efficiency pivot. With only 9 mentions in 30 days, market noise is low — but the cost-performance gap is widening.
