    Proud to share what my team and I have been working on! I use Claude Code almost every day, and wouldn't want to code without it. Just getting started.

    Claude Code has become indispensable for our team. In early testing, Claude completed tasks in a single pass that would normally take 45+ minutes of manual work. Join the limited preview: docs.anthropic.com/en/docs/agents…

    I had a great chat with @lennysan ! We talked about everything from the future of AI and the potential for superintelligence by 2028, to the critical importance of AI safety and why we left OpenAI to start Anthropic. If you're curious about what a world with superintelligence

    This research has been a long time in the making. Super proud of the team! Understanding how language models work mechanistically is the first step to being able to modify that behavior at runtime at a semantic level. This will be a game changer in ensuring AGI is safe.

    I've been using versions of Opus 4 for coding for a bit now. The numbers in the chart don't do it justice. Absolute game changer in staying on track, writing maintainable code, and generally doing what I want and expect rather than reward hacking. A+ job, team!

    Introducing the next generation: Claude Opus 4 and Claude Sonnet 4. Claude Opus 4 is our most powerful model yet, and the world’s best coding model. Claude Sonnet 4 is a significant upgrade from its predecessor, delivering superior coding and reasoning.
    A benchmarking table titled Claude 4 benchmarks comparing performance metrics across various capabilities including coding, reasoning, tool use, multilingual Q&A, visual reasoning, and mathematics.

    Love to see this!! Since we first prototyped Claude (and before it was named that), one of the most surprising and impressive things was how empathetic it seemed to be, and that's only improved over time. Try it and see ❤️

    This is the real game changer. Anyone can search the web, but searching your own data is a pain. Claude's really good at it.

    Claude can also now connect with your Gmail, Google Calendar, and Docs. It understands your context and can pull information from exactly where you need it.

    I've been using our internal prototypes of our MCP-enabled research workflow. It's amazing what Claude digs up. No more manual context stuffing! Hook up your data and give it a shot 🪏🪏🪏
