We're hosting Unsupervised Learning again — a day to explore important recent developments in frontier AI safety. (You will be doing the unsupervised learning, not the models!)
Everything is optional, so drop in and out of sessions as you find useful. We’ll also have plenty of time for 1:1 meetings between people working on similar projects, and space to catch up on work and relax.
This event is for researchers from frontier AI companies and some independent research orgs, but it's invite-only, so please check with us before sharing.
Register here by Friday, November 14 EOD if you haven’t already. Last minute attendees contact isaac@constellation.org

Sessions will be hosted in Constellation’s workspace in Downtown Berkeley. Meals, snacks, and workspace amenities (workstations, call booths, meeting rooms) available to all attendees.
The space will be open from 9:00 until late for conversations and co-working between sessions. Specialized workspace needs are available upon request (contact Isaac, isaac@constellation.org).
We welcome anyone excited to engage with others working on cutting edge AI Safety and frontier models. We welcome thoughtful critics and different intellectual perspectives. Your questions and challenges help shape productive discussions and encourage ongoing dialogue.
We are an independent, nonprofit research center hosting over 200 individual researchers and organizations working on frontier problems in AI safety. You'll connect with many of our affiliates throughout the event, both as speakers and fellow attendees.
