humans is a human-centric frontier AI lab. Our view is that AI should help people work together, so it has to understand people and the relationships between them, not just tasks. Last month we launched Boba (https://boba.app), an assistant you can text one-on-one or add to a group chat. It runs on Ampersand, our first model, trained with RL over millions of simulated days with thousands of simulated people. Boba keeps track of your goals for weeks or months, sets up reminders and calendar invites, uses email and searches the web. In a group chat it reads social context and decides when to speak up and when to stay quiet. Early users have sent it more than a million messages. Looking for product engineers who have done exceptional work on how humans and computers interact. You’ll build the product side of this: new interaction patterns for an AI that lives in group chats, remembers people and acts for them. The founding team comes from xAI, Google DeepMind, OpenAI, Stanford and MIT. Our investors include NVIDIA, GV and SV Angel.
