Claude Opus 4.7 is something of a doubling down on what Anthropic’s models are already good at. Per the company, the latest iteration of its flagship option comes with jumps in performance on coding, engineering, and multi-step tasks. The company claims it is “more thorough and consistent on difficult work, with better results across professional knowledge work.” As with every new model release, this one comes with a fresh set of benchmarking tests to prove its prowess. Claude Opus 4.7 has retaken the top spot for agentic coding among publicly available models, scoring 64.3% on SWE-bench Pro and SWE-bench Verified—two of the main tests of a model’s capabilities of handling complex engineering tasks. Claude Opus 4.7 also improved on 4.6’s standard for agentic computer use (i.e., autonomously navigating across an operating system to complete tasks), and graduate-level reasoning, among other categories. Interestingly, Claude Opus 4.7 represents a slight b
