Claude Opus 4.7 is Anthropic's most capable publicly available model as of April 16, 2026 — and if you use the API for agentic coding or production tasks, you should upgrade today. The headline improvements are a 13% lift on coding benchmarks, a new xhigh effort level designed specifically for long agentic runs, and high-resolution vision support at up to 3.75 megapixels. Based on our analysis of the release, Opus 4.7 resolves 3x more production tasks than its predecessor in Anthropic's internal evals — a meaningful leap that closes the gap between what developers delegate to AI and what actually ships.
Released on April 16, Opus 4.7 arrives as Anthropic's public-facing flagship while Claude Mythos Preview — a restricted model with 93.9% SWE-bench scores — stays locked inside Project Glasswing. For developers building on the public API, Opus 4.7 is now the ceiling, and understanding its capabilities and limits is essential for making good model routing decisions in 2026.
What Changed from Opus 4.6
Anthropic positioned Opus 4.7 as a targeted upgrade across four axes: coding, visual reasoning, agentic control, and instruction fidelity. Here is the detailed breakdown of each improvement.
