Awesome MCP hackathon (world's biggest?) today at Y Combinator with @gumloop_ai Mintlify & @greptileai Amazing projects from MCP observability to voice agents. Great deep dive by Sam Ching. Thanks Max Brodeur-Urbas Han Wang & team Definitely feeling the MCP

Join us from 9:30am PT tomorrow: clau.de/livestream.

It's time to build

Opus 4 + Claude Code + Claude Max plan = best ROI of any AI coding stack right now

In Paris for Vivatech this week and hosting some exciting founder events -- dm for details! 🇫🇷

come build that idea everyone says is stupid Y Combinator on aug 9 at 9am just in time software dynamic AI UI anything that codes by Morph Anthropic Same Benۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗۗ☁️

We built a system that detects highly complex objects NO vision model can find—introducing tool use for vision. 🧵 Say you wanted to detect for the Y Combinator logo in this image. (▶️ see step-by-step thinking) Using our solution, it's able to detect the logo perfectly,

We just launched Claude Opus 4.1 -- excited to keep pushing the frontier on agentic performance

We're also releasing a temporary research preview called "Imagine with Claude". In this experiment, Claude generates software on the fly. No functionality is predetermined; no code is prewritten. Available to Max users for 5 days. Try it out: claude.ai/imagine

it's Claude sonnet 4.5 day!! to celebrate we made you a lil' demo with a bunch of cute touches. you can use it to watch claude generating UIs on the fly. 👏 to Martina Long Si Min Lee michael Sean Strong and many others for sprinting on this! claude.ai/imagine

The Imagine with Claude demo is now expanded to Pro users. Give it a try:

"Imagine with Claude" is available now to all Pro subscribers until this Friday - we're excited to see what you dream up

Demo extended for one more week. Pro and Max users can keep imagining with Claude.

We just launched Haiku 4.5, which gives Sonnet 4 performance at twice the speed and a third the cost.
