Near-Opus Intelligence Available With Claude Sonnet 4.6

The most capable Sonnet yet — upgraded across coding, reasoning, computer use, and agent tasks with a 1M token context window

  • A Full Skills Upgrade Across Every Task

    Released in February 2026, Claude Sonnet 4.6 is Anthropic's most capable mid-tier model to date. It delivers a full upgrade across coding, computer use, long-context reasoning, agent planning, knowledge work, and design — all at the same price as Sonnet 4.5. Developers with early access consistently preferred Sonnet 4.6 over its predecessor and even over Opus 4.5, the flagship model from late 2025. Whether you're writing code, drafting complex documents, or running multi-step workflows, Sonnet 4.6 brings near-Opus quality to everyday tasks inside Chat Smith.

  • Frontier-Level Coding and Software Engineering

    Claude Sonnet 4.6 sets a new bar for mid-tier model coding performance. Achieving 79.6% on SWE-Bench Verified, it comes within 1.2 points of Opus 4.6 — Anthropic's most powerful model — while running at Sonnet speed and price. Improvements in consistency, instruction following, and error correction across long coding sessions make it the preferred tool for developers building complex software. Inside Chat Smith, Sonnet 4.6 helps you plan, implement, debug, and refactor code across multiple files, all within a single conversation.

  • Advanced Computer Use for Real-World Workflows

    One of the most significant upgrades in Sonnet 4.6 is its computer use capability. The model can navigate browsers, fill multi-step web forms, interact with specialized enterprise software, and automate desktop workflows — tasks that previously required custom connectors or human intervention. Anthropic's internal insurance-domain benchmark recorded a 94% accuracy rate, making Sonnet 4.6 the most capable model tested for complex, real-world office software automation. This opens entirely new possibilities for productivity inside Chat Smith.

  • 1 Million Token Context Window in Beta

    Claude Sonnet 4.6 introduces a 1 million token context window in beta, enabling it to process entire codebases, lengthy legal documents, large collections of research papers, or full project histories in a single request. Anthropic also implemented an automated context compaction protocol that maintains coherence and token efficiency even in extremely long sessions. This means Sonnet 4.6 can stay focused and accurate across the longest, most complex interactions — without losing the thread or requiring you to start over.

  • Powerful Agentic Planning and Multi-Step Execution

    Claude Sonnet 4.6 is built for agentic work. It can handle long-running, multi-step autonomous tasks with improved instruction following, smart tool selection, and reliable error correction over extended sessions. When paired with Claude Haiku 4.5, Sonnet 4.6 can create detailed multi-step plans while Haiku executes individual subtasks — a powerful combination for complex, automated workflows. Inside Chat Smith, this makes Sonnet 4.6 your most capable AI partner for ambitious, multi-stage projects that demand both intelligence and reliability.
