PSA: Claude, @calacademy's beloved albino alligator, now has a 24/7 livestream — and it's giving us life. Watch: calacademy.org/learn-explore… The webcam is sponsored by @AnthropicAI — who, fittingly, also has a virtual assistant named Claude. The collab we didn't know we needed. 🐊🤝

Sometimes it’s the little features that bring me a lot of joy. Recently added this little gem to our Claude iOS app to be able to quickly capture and analyze photos. Just a quick tap from your Lock Screen or Control Center. Whether you want to identify a plant, translate a sign, or transcribe whiteboard notes it’s pretty convenient to have at your fingertips.

A few researchers at Anthropic have, over the past year, had a part-time obsession with a peculiar problem. Can Claude play Pokémon? A thread:

Really excited about Claude 3.7 Sonnet and its thinking mode. Our mobile apps support it too :)

Introducing Claude 3.7 Sonnet: our most intelligent model to date. It's a hybrid reasoning model, producing near-instant responses or extended, step-by-step thinking. One model, two ways to think. We’re also releasing an agentic coding tool: Claude Code.

We also now have an "Ask Claude" Shortcut and App Intent. The standalone shortcut lets you ask claude a quick question from anywhere, and the Intent can be used to chain together different actions in the Shortcuts app (attached is a silly example)

Introducing an upgraded Claude 3.5 Sonnet, and a new model, Claude 3.5 Haiku. We’re also introducing a new capability in beta: computer use. Developers can now direct Claude to use computers the way people do—by looking at a screen, moving a cursor, clicking, and typing text.
