Anthropic launched Claude Opus 4.7 as the latest generally available Opus model. [2][4][5][6]
The main product-positioning change called out in the available sources is a focus on advanced software engineering. [2][6]
Developers can access it in the Claude API under the model identifier i.j4i.i2
GitHub also announced Opus 4.7 availability in GitHub Copilot, which indicates ecosystem rollout beyond Anthropic’s own interface. [5]
Press coverage says Anthropic is presenting Opus 4.7 as less risky than its separate “Mythos” model line. [1][3]
What I cannot cleanly verify from the current source set is the exact delta versus older Opus releases such as Opus 4.1 or Claude 3 Opus on benchmarks, context window, pricing, or architectural changes. The evidence returned here does not expose those details clearly enough, so the right answer on those points is: Insufficient evidence. [6][7]
If you want, I can next turn this into a tighter “4.7 vs 4.1 vs Claude 3 Opus” comparison, but I’d want either Anthropic’s model docs URLs or permission to do a deeper source pass.
