  Is Sonnet 4.6 like my girl Opus, but with less expensive tastes? Sign me up.

  Anthropic is one of those companies where the product is so good that I don't care how much they lib out. Banning them from DOW would be a massively self inflicted error

  Claude Sonnet 4.6 is the new leader in GDPval-AA, slightly ahead of Anthropic's Opus 4.6 on agentic performance of real-world knowledge work tasks less than two weeks after its launch In our pre-release testing with @AnthropicAI, Sonnet 4.6 reached an ELO of 1633 using the [image…

  NEW: Anthropic releases Claude Sonnet 4.6 Nears Opus-level performance across coding and reasoning at Sonnet pricing ($3/$15 per mil tokens). Computer use scores have gone from single digits last year to 72.5% now 📈 + a 1M token context window [video]

• @felixrieseberg Felix Rieseberg on x

  Fun nugget from Sonnet 4.6: With a 1M context window, the model is better at long-horizon planning.  In the Vending-Bench Arena, models compete to run a simulated business.  Sonnet 4.6 developed a new strategy: invest heavily in capacity for the first 10 months, then pivot hard t…

  This is Claude Sonnet 4.6: our most capable Sonnet model yet. It's a full upgrade across coding, computer use, long-context reasoning, agent planning, knowledge work, and design. It also features a 1M token context window in beta. [video]

• @alexalbert__ Alex Albert on x

  Sonnet 4.6 is here. It's our most capable Sonnet model by far, approaching Opus-class capabilities in many areas. Very excited for folks to try this one out. The performance jump over Sonnet 4.5 (which was released just over four months ago) is quite insane.

  Underrated dev upgrade from today's launch: Claude's web search and fetch tools now write and execute code to filter results before they reach the context window. When enabled, Sonnet 4.6 saw 13% higher accuracy on BrowseComp while using 32% fewer input tokens.

• @andonlabs @andonlabs on x

  Claude Sonnet 4.6 is 2nd on Vending-Bench 2.  We previously showed that Opus 4.6 is incredibly capable, achieving SOTA with tactics that are impressive but could be considered ethically concerning.  Sonnet is almost as impressive, and almost as concerning, at a third the price.

• @bcherny Boris Cherny on x

  Sonnet 4.6 is now live in Claude Code. It's cheaper than Opus 4.6 and nears Opus-level intelligence, and devs in early testing often preferred it to Opus 4.5. Now the default for Pro and Team plans.

• @zapier @zapier on x

  Sonnet 4.6 just dropped. We got early access. Some thoughts 👇 We ran @Claude Sonnet 4.6 against 4.5 and Opus 4.6 on real workflow automation tasks: conditional routing, scheduling coordination, contract flows. Sonnet 4.6 is a clear step up from it's 4.5 version. Stronger [image]

• @llmjunky @llmjunky on x

  Been waiting for this. For those of you asking “is the $20 plan worth it,” I believe the answer to that question is now yes. Claude models are quite good at a variety of things that I can't replicate with other models. Credit where it's due. Competition is king. We all win.
