Anthropic announced the release of its latest AI model, Claude Opus 4.7, which the company describes as a notable improvement over Opus 4.6 but less capable than the unreleased Opus Mythos Preview.
The launch of Claude Opus 4.7 emphasizes enhancements in performance for tasks related to coding, engineering, and multi-step processes. The model reportedly shows improvements in thoroughness and consistency, particularly in challenging professional knowledge applications.
Benchmarking tests confirm that Claude Opus 4.7 has regained the top position for agentic coding, achieving a score of 64.3% on both SWE-bench Pro and SWE-bench Verified. These are key metrics assessing a model’s ability to manage complex engineering tasks. The new version also surpassed its predecessor, Opus 4.6, in agentic computer use and graduate-level reasoning metrics.
However, the model recorded a minor decline in cybersecurity vulnerability reproduction, scoring 73.1%, down from 73.8% for Opus 4.6. Anthropic attributed this decrease to new safety measures that block requests associated with high-risk cybersecurity scenarios.
The release of Claude Opus 4.7 also appears to support the promotion of the more powerful Claude Mythos Preview. This upcoming model has demonstrated exceptional performance in tests, significantly outperforming others. “We stated that we would keep Claude Mythos Preview’s release limited and test new cyber safeguards on less capable models first,” Anthropic noted. They added that Opus 4.7 is the first model to have these new safeguards implemented.
Claude Opus 4.7 is now available across all Claude products and through the company’s API, with pricing unchanged from previous versions.
