Anthropic's Claude Opus 4.7

**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.
