About

Claude Opus 4.1 is an incremental upgrade to Claude Opus 4 that boosts coding, agentic reasoning, and data-analysis performance without changing deployment complexity. It raises coding accuracy to 74.5 percent on SWE-bench Verified and sharpens in-depth research and detailed tracking for agentic search tasks. GitHub reports notable gains in multi-file code refactoring, while Rakuten Group highlights its precision in pinpointing exact corrections within large codebases without introducing bugs. Independent benchmarks show about a one-standard-deviation improvement on junior developer tests compared to Opus 4, mirroring major leaps seen in prior Claude releases.

About

​Rector is a PHP tool that you can run on any PHP project to get an instant upgrade or automated refactoring. It helps you with PHP and framework upgrades, in-house framework migrations, and improving your code quality to deliver features faster than the competition. In the hands of an expert, Rector massively reduces your work time. Where a project upgrade from PHP 8.0 to 8.3 would take 3 months, Rector is done in 3 days. You can learn it yourself from documentation, or to save time and start upgrading today, hire our upgrade team. We've helped 50+ companies to improve their PHP code and reduce technical debt. Improves your code quality code to the highest possible level. The knowledge is embedded in the Rector rules and sets. All you have to do is to run and apply them to your code base. Once you get past PHP 8.0 and have a full-blown Rector CI setup, the time to upgrade to the latest PHP drops to hours.
