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.

Couldn’t be happier to work here today

[Sam Bowman @sleepinyourhat]

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.

Fast browser and computer use will be critical for completing last mile tasks. I’m excited to share some early experimentation with low latency browser use, plus a demo you can play with starting today!

[Claude @claudeai]

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.

[Andi Peng @TheAndiPenguin]

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

[Ludwig Schmidt @lschmidt3]

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.

Anthropic is hosting a recruiting social in NYC targeted at the quant trading industry! Signup in thread.

I enjoyed trading systems, and Anthropic combines the technical depth of trading with being in the fastest most impactful area of tech.

And I am excited to announce that I have joined Anthropic, Switzerland! 🇨🇭

Anthropic is setting up a new office in Zurich, expanding its global presence. I am super excited to build a team here, where we will be working on LLM training, focussing on developing multimodal capabilities...

[Tarasha Khurana @tarashakhurana]

Excited to present new work on using diffusion priors for video amodal segmentation and content completion!

The new Claude 3.5 Sonnet is the first frontier AI model to offer computer use in public beta.

While groundbreaking, computer use is still experimental—at times error-prone. We're releasing it early for feedback from developers.

[Achal Dave @achalddave]

@Kenneth_Marino @rajammanabrolu Yeah I mean Pittsburgh’s at least a few miles from middle of nowhere

[Kenneth Marino @Kenneth_Marino]

Very excited to announce that in Fall 2025, I will be starting as an Assistant Professor at the Kahlert School of Computing at the University of Utah @UUtah.
