Jacob was a senior researcher who joined Anthropic in May. My Anthropic colleagues and I had been trying to recruit him for ~2 years, because we knew he was a strong researcher at OpenAI. Before he left, I pitched him to stay and join my team, and I was sad he decided to leave, 2.3M views · 21.1K likes · 3.1K reposts · 805 replies Open on X →

Today, we are launching Tinker grants of up to $50,000 in credits for safety research on open-weight models. We share some project ideas that excite us below; if you’re working on a safety project that could be accelerated by additional Tinker credits, we want to hear from you! 274.3K views · 1.5K likes · 130 reposts · 42 replies Open on X →

We are hiring! This may be the best time ever to join: we are incredibly bandwidth bottlenecked and there is a lot of support for almost any impactful misalignment work you can think of. I think we also have a pretty good epistemic environment and a very fun team Topics: 149.8K views · 641 likes · 53 reposts · 19 replies Open on X →

Grateful for @janleike and his leadership over the years. With models like Mythos, the stakes for alignment have never felt higher at Anthropic, and I'm looking forward to helping to continue scaling up our work here.
