1/ Meet Claude Sonnet 4.5 Claude Sonnet 4.5 just launched and it's really good at coding. It's the best in the world right now. It can build complex AI assistants, use computers like a human, and solve tough math and reasoning problems. The best part? It costs the same as the

2/ Amazing at Writing Code This model scored 77.2% on a hard coding test (82% when given more tries). It can work on complicated coding projects for over 30 hours without losing focus. Companies using it say it finds security problems 44% faster and makes zero mistakes on code

3/ Using Computers Like a Human Claude can now navigate websites, fill out spreadsheets, and do real computer tasks, scoring 61.4% on tests (up from 42.2% just four months ago). There's a new Chrome extension that lets Claude work right in your browser to help complete tasks.

4/Better Tools for Everyone Big updates everywhere: Claude Code now saves your work with "checkpoints" so you can undo mistakes. It works in VS Code now. The regular Claude app can run code and create files (like spreadsheets and presentations) while you chat with it.

5/Build Your Own AI Helpers For the first time, developers can use the same technology that powers Claude Code. All the hard problems, like making AI remember things across long tasks, have been solved. Now you can build your own powerful AI tools using these building blocks.

6/ Built to Be Safe This is the safest, most reliable Claude model yet. It lies less, seeks power less, and doesn't encourage weird thinking. It's better at defending against hacking attacks. Special safety features protect against dangerous uses. Available to use right now

🚨 Hugging Face & Oxford just dropped the playbook for robot intelligence. It’s called LeRobot, and it’s basically the “PyTorch of robotics.” End-to-end code. Real hardware. Generalist robot policies. All open source. Here’s why this is huge: • Robots can now learn from data
