Claude Opus 4.7 Sets New SWE-Bench Record at 87.6%

What Is Claude Opus 4.7?

Anthropic released Claude Opus 4.7 on April 17, 2026, scoring 87.6% on SWE-bench Verified — up from 80.8% on the previous version. This narrowly retakes the top spot for the most powerful generally available large language model. The update also triples vision resolution and introduces a new "xhigh" effort level for complex tasks.

Why Does This Matter for Developers?

The SWE-bench benchmark measures how well AI can solve real GitHub issues — coding bugs, feature requests, and pull requests. An 87.6% score means Opus 4.7 can autonomously resolve nearly 9 out of 10 real-world software engineering tasks. For solo developers and small teams, this translates to dramatically faster debugging and shipping cycles.

What Else Changed?

Vision resolution is now 3x sharper, making Claude significantly better at analyzing screenshots, diagrams, and design mockups. The xhigh effort level lets the model spend more compute on difficult problems — ideal for architecture decisions and complex refactoring. Pricing remains unchanged from the previous Opus release.
