@graceluo_ @feng_jiahai @trevordarrell @AlecRad @JacobSteinhardt congrats, grace!

We trained diffusion models on a billion LLM activations, and we want you to use them! New preprint: Learning a Generative Meta-Model of LLM Activations Joint work with @feng_jiahai, @trevordarrell, @AlecRad, @JacobSteinhardt. More in thread 🧵

@charlie_ruan congrats, charlie!

Announcing OpenThoughts-Agent with an incredible team — a data-centric effort on TerminalBench-style tasks, built with SkyRL+Harbor 💻🤖 Co-leading the RL team over the past month has been a blast, and we’re just getting started! (1/n) 🧵

New paper from DeepSeek, link in comments!

@divgarg @agi_inc congrats, div!

We’ve been building in stealth at @AGI_Inc. Today, we’re ready to share it. Meet AGI Mobile. An AI that can actually use your phone. You talk. It executes. It uses any apps faster than you. This is what Siri was meant to be. Limited early access. 👉 agi.app

@_albertgu @CarnegieMellon congrats, albert!

a silly milestone but one nonetheless - 20k citations! although i don't think it's a very useful metric (i got my position at @CarnegieMellon with ~700 citations iirc), i'm mostly proud of the fact that it's predominantly first author papers that i spent years pushing on a single thread on 😎 now for christmas could santa help my X followers hit 20k too 🥹🎄

@ProbyShandilya Hey Proby, I registered a while back, could you please approve me? Thanks!

Tomorrow! If you're in SF and love enterprise software, we'd love to see you there

@MayeeChen congrats, mayee!

Thrilled to have contributed to Olmo 3! The best fully open 32B model (data, training recipes, checkpoints and more!) As an intern at AI2 these last 8 months, I’ve grown to deeply appreciate the careful science, iteration, and collaboration that go into models like this and have learned so much from the team. I am more optimistic than ever about the future of open-source and data-centric research right now. My particular contribution was working on the Dolma 3 data mix 👩‍🍳 I was able to apply ideas from some of my earlier mixing work, explore new problem settings, and see firsthand the data challenges that arise when building datasets intended for real models at scale. More on this coming soon!

@askalphaxiv @MenloVentures @haystackvc @Shakti_VC @conviction @upfrontvc @ericschmidt @SebastianThrun @sarahookr congrats, team!

We just raised a $7M Seed round co-led by @MenloVentures and @haystackvc with participation from @Shakti_VC, @conviction and @upfrontvc 🚀 We're honored to have the support of incredible angels including @ericschmidt, @SebastianThrun, @sarahookr Join us: alphaxiv.org/careers

Today we’re introducing Cogent Community, a free solution for security practitioners. It brings our agentic AI together with VulnCheck, the premier source for vulnerability and exploit intelligence, so defenders can level the playing field against AI-enabled adversaries.

Thrilled to announce Sonic 3! 🚀 Faster, smarter, and now fluent in more languages — plus expressive voice control. Next time DoorDash messes up, try our angry voice for that full refund and some 💵

@rohan_tib congrats, rohan!

@neilkale @scale_AI @_zifan_wang congrats, neil!

Excited to share my summer research at @scale_AI , advised by @_zifan_wang . Go check it out!

@Jenyangwong @baseten @codeiumdev @DecagonAI @usepatch @mercor_ai @Jenyangwong would love to join the tech talk y'all are organizing on 3/27, my RSVP is still on pending

First Tech Talk of the year! Name a better lineup: @baseten @codeiumdev @DecagonAI @usepatch @mercor_ai & Doss Register here to join us: lu.ma/SF-TechTalk

If you’re interested in getting started with ML Research (i.e. as an undergrad/masters student), I recently gave a talk at CMU about how to find your first research and have a successful first project :) Video: m.youtube.com/watch?v=XWItsm… Slides: maxwelljon.es/assets/pptx/DS… 1/2

@jonchu @jonchu Sapien is doing number 3, Harvey is doing number 4

I've been looking for 3 & 4 if anyone knows credible teams doing this!

@natfriedman I have a lego foundation model, would love to come @natfriedman

Hmm, a lot of you really like to build legos. I got hundreds of DMs, far exceeding the max parallelism of this build!

@conconconling @RonNachum @StanfordGSB @neo @emilyycohen @suzannexie @apartovi congrats, connor! also in the bay area, we should meet up sometime!

Life update: I’ve moved to SF, declined my offer to @StanfordGSB, and joined @neo as an investor! Before getting into why I’m incredibly bullish on Neo, I want to share my origin story that I’ve largely kept to myself: I grew up in a small town in China, bordering North Korea and Russia. My dad left home at 14 as his family struggled to provide, and my mom used to walk 4 hours a day to school since owning a bike was too much of a luxury. While neither of them went to university, their journey of escaping poverty through hard work inspired me to habitually pursue excellence. A year into high school, I became fascinated with the idea of coming to the U.S. for college and wanted to drop out to carve out this new path. To my surprise, while unsure what it really entailed, my parents supported my decision as they believed I could create my own fate. In the subsequent 2 years, I taught myself the SATs / 10 APs in year 1 and moved to Beijing by myself in year 2 working for 3 nonprofits before coming to Penn – and the rest is history. Life has taken me to places I wouldn’t have dreamed of 10 years ago, thanks to my 16-year-old self who took a leap of faith and embarked on my own 0-to-1, but even more so to my parents who believed in me early when it wasn’t obvious or easy. I jumped into early-stage investing in 2023, and it quickly became obvious to me that spotting ambitious builders early, truly understanding them on a personal level, and helping them realize their full potential brings me endless energy and joy… and that’s exactly what brought me to @neo. Built on the ethos of investing in people, Neo has 3 deeply interconnected pillars: Neo Scholar, Accelerator, and Seed Fund. Through the Scholar program, Neo invests significant time and resources to help the brightest technical builders in college become tech leaders. Launched in 2017, Neo Scholar has become North America’s most high-signal and rigorously vetted talent community, and a subset of Scholars have founded companies like @cursor_ai, @cognition_labs, and @pika_labs. The 3-year-old Accelerator invests in 20 teams per batch, one batch per year with portco’s like @AnteriorAI, @moment, @Calderaxyz, and @sapienai (@RonNachum introduced me to Neo!). Through the Seed Fund, Neo primarily leads / co-leads (pre)seed rounds into technical teams like @Kalshi, @chaidiscovery, @bluesky, @TrustVanta, @bubble, @cobotco, and @tryramp. As the tech landscape evolves at unprecedented speeds, the only constant in startups is people – @neo is world-class in backing the best people at the earliest stages, and I’m truly excited to amplify this mission in the years to come! With that, I've officially declined the early admission offer I received from the GSB 4 years ago. While the offer has served as a safety net and allowed me to explore freely in the last 4 years, knowing that the best founders always go all in, it’s time for me to do the same at Neo :)
