Anthropic launched Claude Opus 4.7, its most capable Opus model yet, featuring stronger coding and agentic performance, a new tokenizer, and improved long-context handling with a new xhigh reasoning tier. Benchmarks show substantial gains, including SWE-bench Pro 64.3%, SWE-bench Verified 87.6%, and TerminalBench 69.4%, with top rankings on Vals Index and GDPval-AA. Technical changes include a new tokenizer and increased image input resolution to 3.75MP. Some long-context benchmarks showed mixed results, with a shift in focus from MRCR to Graphwalks.

Adoption was rapid across tools like Cursor, VS Code, Replit Agent, and Perplexity. Meanwhile, OpenAI expanded Codex into a broader computer agent with Mac computer use, in-app browser, image generation/editing, 90+ plugins, multi-terminal support, SSH remote devbox access, and richer file previews. A new vertical life-sciences model, GPT-Rosalind, was also introduced.
