Claude Sonnet 4.6 Brings Improved Coding, Computer Use, and Office Tasks

Source: MacRumors

Anthropic today updated its Sonnet model to version 4.6, describing it as the most capable Sonnet model to date with upgrades across coding, computer use, long‑context reasoning, agent planning, knowledge work, and design.

Claude Sonnet 4.6 is now the default for users on Free and Pro plans and features an expanded 1 M token context window.

Key improvements

• Coding: Better consistency and instruction following.
• Computer use: Enhanced ability to perform tasks that involve interacting with operating systems and applications.
• Office tasks: Can now handle tasks that previously required an Opus model, such as navigating complex spreadsheets or completing multi‑step web forms.
• Long‑context reasoning & agent planning: More reliable performance with extended context lengths.
• Design & knowledge work: Improved output quality for creative and analytical tasks.

Anthropic notes that Sonnet 4.6 exhibits “a broadly warm, honest, prosocial, and at times funny character, very strong safety behaviors, and no signs of major concerns around high‑stakes forms of misalignment.” It delivers Opus‑level intelligence at a more affordable price, making it practical for a wider range of applications. While Opus 4.6 remains superior for agentic coding, agentic code use, and multidisciplinary reasoning, Sonnet 4.6 offers measurable gains over Sonnet 4.5.

Claude 4.6 is available as of today for all Claude plans, and Anthropic has also introduced file creation, connectors, skills, and compaction for free users.
