Claude

One of the first questions teams ask about a new model is how much it will cost. Here's how Opus 5 and Opus 5.5 compare on one Claude Code task, using the same tokens.

Nate, a designer at Anthropic, used to start a presentation by staring at a blank slide. Now he goes for a walk. He talks the whole idea into a voice memo on his phone, messy and unstructured, then hands the transcript to Claude with one instruction: turn my exact words into a deck, organized so it makes sense. Claude Slides builds it in Anthropic’s brand, so there’s no hunting for fonts or templates. For the next two weeks, start a deck, doc, or design in the Claude app, and the work that follows in that conversation uses 50% less of your 5-hour limits. It applies automatically from your first one and runs through October 15 on Pro, Max, and Team plans. How it works: https://lnkd.in/eTX4sEDj Create a deck with Claude: https://lnkd.in/dyicbdsF

Claude Founder House is coming to San Francisco for SF Tech Week (October 6–8) and Stockholm (October 14). Both have talks, workshops and office hours with the Anthropic team, and time to meet other people building with Claude. Whether you're a founder, a CEO or a builder, there's a session for you.

Claude for Government is out of beta and generally available. Federal and state agencies can deploy the Claude desktop app, including Cowork and Claude Code, in a FedRAMP High authorized environment. New with general availability: • No seat fees; agencies prepay for usage, with a hard not-to-exceed cap • Department admins can allocate usage to sub-agencies and set limits by seat tier • Claude Code on the command line and Claude for Microsoft 365, in early access Read more: https://lnkd.in/eFqaNkbp

Claude Sonnet 5.5 has joined Opus 5.5 in the model selector. When you know what done looks like, Sonnet 5.5 gets you there faster and for less. When you're still working that out, start with Opus 5.5.

Introducing Claude Sonnet 5.5, the second model in the Claude 5.5 family. It's a faster, lower-cost complement to Claude Opus 5.5, strongest at well-scoped everyday tasks, fixing bugs, and creating polished documents, slides, and spreadsheets. It also has a strong eye for design. Sonnet 5.5 is a clear upgrade over Sonnet 5. It runs more than 30% faster and costs up to 30% less for most work. It's priced the same per token, but it typically needs far fewer tokens to do the same work. Like Opus 5.5, it writes more clearly than our previous generation of models, and its speed makes it well suited to fast iteration. On our automated behavioral audit, Sonnet 5.5 improves on or matches Sonnet 5 on most measures of alignment and honesty. It's also the first Sonnet model with cybersecurity safeguards similar to those on our most capable models. Routine software development is unaffected. Sonnet 5.5 is available everywhere today. Claude Haiku 5.5 will join the family in the coming weeks. Read more: https://lnkd.in/eKEYTQXN
