Claude Opus 4.7 is now generally available, offering significant improvements in advanced software engineering and handling complex, long-running tasks with consistency and self-verification.
It features substantially better vision with higher resolution image support (up to ~3.75 megapixels) and excels in professional tasks like creating interfaces, slides, and documents.
Opus 4.7 demonstrates notable performance gains across benchmarks, including a 13% lift on a 93-task coding benchmark and improved efficiency in multi-step workflows.
Despite being less capable than Claude Mythos Preview, it is the first model released with cybersecurity safeguards, and security professionals can join the Cyber Verification Program for legitimate use.
It shows strong feedback from testers, with improvements in autonomy, reasoning, tool-call accuracy, and error recovery, making it effective for agentic and enterprise workflows.
Key updates include a new 'xhigh' effort level, task budgets in the API, and features like '/ultrareview' in Claude Code, along with changes in tokenizer affecting token usage.
