New Features

• 1 M token context window
• Full upgrade of the model’s skills across:
  • Coding
  • Computer use
  • Long‑context reasoning
  • Agent planning
  • Knowledge work
  • Design

“Sonnet 4.6 brings much‑improved coding skills to more of our users. Improvements in consistency, instruction following, and more have made developers with early access prefer Sonnet 4.6 to its predecessor by a wide margin. They often even prefer it to our smartest model from November 2025, Claude Opus 4.5.” – Anthropic

Performance Gains

• Tasks that previously required an Opus‑class model (including real‑world, economically valuable office tasks) are now handled by Sonnet 4.6.
• Significant improvement in computer‑use abilities compared to earlier Sonnet models.

Free‑Tier Update

The free tier now uses Sonnet 4.6 by default, with “file creation, connectors, skills, and compaction” included.
