Anthropic’s Claude Opus 4.7 Debuts With Immediate GitHub Copilot Integration

A new tokenizer and higher-compute mode could increase token usage for many tasks.

Overview

  • Microsoft integrated Claude Opus 4.7 into GitHub Copilot across nine tools and will make it the default choice for Copilot Pro+.
  • Anthropic released the model to the public and says it tackles harder coding jobs, runs long tasks more reliably, and designs its own checks before outputting code.
  • The company also highlights stronger vision skills that read higher‑resolution images and produce cleaner slides, documents, and interface mockups.
  • Anthropic warned that a new tokenizer can use about 1.0 to 1.35 times more tokens for the same content, and a high‑compute mode can add more output tokens.
  • Coverage describes a tiered lineup in which the restricted Claude Mythos remains the most capable model, with benchmarks citing Opus 4.7 ahead of GPT‑5.4 and Gemini 3.1 Pro on several tasks yet behind the closed Mythos preview.
