100-word summary
Anthropic's Claude Opus 4.7 ships today with built-in output verification, meaning the model checks its work before handing it back. That's particularly useful for long-running tasks like continuous integration pipelines, where a single hallucinated command used to blow up hours of automation. The new version also processes higher-resolution images, so it can generate cleaner slide decks and design mockups. Pricing stays flat. The catch? Anthropic admits Opus 4.7 is less capable overall than its unreleased Mythos Preview model. Think of this as the stable, production-safe version while the riskier stuff stays in the lab. Your chatbot won't get smarter at small talk, but it might finally stop breaking your build.
