Excited to share our new-and-improved 1B models trained with DataComp-LM!
- 1.4B model trained on 4.3T tokens
- 5-shot MMLU 47.5 (base model) => 51.4 (w/ instruction tuning)
- Fully open models: public code, weights, dataset!

Today, we’re releasing a feature that allows Claude to control your computer: Mouse, keyboard, and screen, giving it the ability to use any app.
I believe this is especially useful if used with Dispatch, which allows you to remotely control Claude on your computer while you’re away.

We're disappointed by these attacks, but not deterred.
I'm proud to work here. If you've been moved by this week's events, consider applying to join me.

Sonnet 4.6 also shows a major improvement in computer use skills.
Early users are seeing human-level capability on tasks like complex spreadsheets and multi-step web forms.

📣 Anthropic Zurich is hiring again 🇨🇭
The team has been shaping up fantastically over the last months, and I have re-opened applications for pre-training.
We welcome applications from anywhere along the "scientist/engineer spectrum". If building the future of AI for the general good and working in a highly collaborative environment resonates with you, take a look:

This is why I consider Ludwig one of the best academics of recent years.
He's been leading the most impactful work that academics usually shy away from. Not just once, not just twice, but many times over!
And his pivot from robustness was amazing to witness, hats off.

Proud of what we cooked but even prouder of incremented integer naming 🥹
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.
ALT 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.

Very excited about our new agent benchmark! I think it's a nice way of evaluating how well agents can do complex task in terminal (command line) environments.

@ethansdyer and I have started a new team at @AnthropicAI — and we’re hiring!
Our team is organized around the north star goal of building an AI scientist: a system capable of solving the long-term reasoning challenges and core capabilities needed to push the scientific frontier. We're thinking across the full model stack. Right now, we're focused on improving models' ability to use computers — both as labs for long-horizon tasks and as a key bottleneck in scientific workflows.
