Announcing DeepSWE 🤖: our fully open-sourced, SOTA software engineering agent trained purely with RL on top of Qwen3-32B. DeepSWE achieves 59% on SWEBench-Verified with test-time scaling (and 42.2% Pass@1), topping the SWEBench leaderboard for open-weight models. Built in…
Check out our new paper “Generative Modeling of Weights: Generalization or Memorization?” — we find that current diffusion-based neural network weight generators often memorize training checkpoints rather than learning a truly generalizable weight distribution!

It's exciting to apply diffusion models to new domains! But it requires careful evaluation, esp. regarding memorization. Our paper highlights this need. Shout-out to @zeng_boya for leading this work. paper: arxiv.org/abs/2506.07998 project page: boyazeng.github.io/weight_memoriz… video:…
Can GPT, Claude, and Gemini play video games like Zelda, Civ, and Doom II? 𝗩𝗶𝗱𝗲𝗼𝗚𝗮𝗺𝗲𝗕𝗲𝗻𝗰𝗵 evaluates VLMs on Game Boy & MS-DOS games given only raw screen input, just like how a human would play. The best model (Gemini) completes just 0.48% of the benchmark! 🧵👇
Conference reviewing should be in the form of annotating on paper like google doc comments. So you know reviewers actually read the paper and less of over-general AI generated comments. And it’s smoother experience writing reviews too without jumping between paper and writing.
Very productive conversations with @melissapan @IntuitMachine @sh_reya @tonychenxyz @cyrusnewday. My tl;dr -> There are at least 4 different concepts here, and it's essential to study them separately. 1) Structured programming to fully express your intent or control on the…

Glad to see Arena-Hard as the flagship benchmark for Qwen3! All of us really appreciate the works Qwen team have done, their works are amazing! 🙌 Evaluate your model on Arena-Hard and our recently released Arena-Hard-v2.0 at github.com/lmarena/arena-…

Claude can play Pokemon, but can it play DOOM? With a simple agent, we let VLMs play it, and found Sonnet 3.7 to get the furthest, finding the blue room! Our VideoGameBench (twenty games from the 90s) and agent are open source so you can try it yourself now --> 🧵
Introducing Open Deep Research! A fully open-source Deep Research tool that: • writes comprehensive reports • does multi-hop search and reasoning • generates cover images & pod-casts! We’re releasing everything: evaluation dataset, code and blog.🔥 Example output report👇
Life update: I’ll be joining @PrincetonCS as a PhD student starting fall 2025! It was a very very difficult decision. I enjoyed people I talked to and their research at every place. My biggest thank you to everyone who has helped me along the journey! Excited for what’s to come!
LLM agents are still in their early stages—struggling with simple tasks while holding scary levels of access and control. We need to focus on better safeguards and reliability before scaling their power.

Rolling out a new inference stack for DeepSeek R1 @togethercompute that gets up to 110 t/s on the 671B parameter model!
Do you remember when you joined X? I do! #MyXAnniversary
"I'm too slow at ML research" - every researcher ever. Over years of trying different strategies, I've landed on a few that have really helped me. I've written them down here, hoping it helps others & becomes a community resource! open.substack.com/pub/miachiquie…
