Keeping their focus on advanced software engineering, Anthropic says the new model especially shows gains on «the most difficult tasks.»

The new Opus should also be better at reading images for designs on interfaces, slides and documents.

Benchmarks posted by Anthropic tells a story of a significantly improved model over Opus 4.6, and jumping ahead of Gemini 3.1 and GPT-5.4 in most cases.

Opus 4.7 is not as powerful as the Mythos model used in «Project Glasswing», being much less capable at cyber skills, having been «differentially reduced» in training. It also automatically detects and blocks «prohibited or high-risk cybersecurity uses.»

Anthropic says they will use what they learn from the 4.7 release to inform a broader release of Mythos.
