Anthropic just shipped Sonnet 4.6.

The benchmark that matters: 72.5% on OSWorld — real computer tasks like filing expenses, navigating software, completing multi-step workflows.

  • Opus 4.6: 72.7%

  • Sonnet 4.6: 72.5%

  • GPT-5.2: 38.2%

The mid-tier model now performs at the premium tier. At mid-tier pricing.

Someone posted a demo of Claude logging into Shopify, finding delivery settings, changing pricing thresholds, then verifying across pages that everything saved correctly.

Cost: $0.30.

That’s the shift. From “AI that helps you work” to “AI that does the work.”


The Numbers

  • 72.5% on real computer operation Almost matches Opus. Nearly doubles GPT-5.2.

  • 94% on insurance workflow completion Claims, error correction, end-to-end processing.

  • 1M tokens context window (beta) Entire codebases. Complete legal docs. Full picture.

  • $3/$15 per million tokens Same as 4.5. Performance jumped. Price stayed flat.


What Makes This Different

Three things working together:

  1. Computer use that actually works Pop-ups, loading states, multi-page flows. It adapts when interfaces look different than expected.

  2. Extended thinking for complex operations Plans the sequence. Anticipates issues. Catches its own mistakes. This is what makes 94% accuracy possible.

  3. Context that spans entire projects 1M tokens means you can give Claude the full situation, not carefully selected snippets.



Who This Changes Things For

  • Founders: Fewer integrations, more agents. Claude operates your existing tools.

  • Small businesses: Admin tasks become $0.30 operations instead of $30/hour contractors.

  • Enterprises: Automation without custom development. Describe what you want, watch it happen.
