    📷📷📷New paper! (with @OpenAI) 📷📷📷 We trained weight-sparse models (transformers with almost all of their weights set to zero) on code: we found that their circuits become naturally interpretable! Our models seem to learn extremely simple, disentangled, internal mechanisms!

    (I spelled the first post wrong) Life update: I just joined @OpenAI to work on applied interpretability! Excited to train big models :)

    This represents a 10× scale-up from our previous work and demonstrates that large-scale model training is no longer confined to large corporations but can be achieved through distributed, community-driven approaches. Technical report: github.com/PrimeIntellect… Blogpost:

    Woah, a new OpenAI interpretability paper?

    We’ve developed a new way to train small AI models with internal mechanisms that are easier for humans to understand. Language models like the ones behind ChatGPT have complex, sometimes surprising structures, and we don’t yet fully understand how they work. This approach

    AI researchers will literally negotiate $100 million comp packages by themselves but they won’t play poker for more than $50 buy-ins

    🧵Can we understand vision language models by interpreting linear directions in their latents? Yes! In our new paper, Line of Sight, we use probing, steering, and SAEs as useful tools to interpret image representations within VLLMs.

    I think the main other stuff I found interesting was: 1. distilling reasoning from R1 (this seems like a kind of weak-to-strong posttraining?) 2. I haven't seen anyone do multi token prediction at this scale, maybe its a free lunch for all autoregressive tasks.

    Some news: We're building the next big thing — the first-ever AI-only social video app, built on a highly expressive human video model. Over the past few weeks, we’ve been testing it in private beta. Now, we’re opening early access: download the iOS app to join the waitlist, or
