Today, @ekindogus and I are excited to introduce @periodiclabs. Our goal is to create an AI scientist. Science works by conjecturing how the world might be, running experiments, and learning from the results. Intelligence is necessary, but not sufficient. New knowledge is…

In case you didn't know my recent work Single-stream Policy Optimizaton (SPO), a group-free low variance policy gradient algorithm. Check this blog out: zhongwenxu.notion.site/Single-stream-… and paper: arxiv.org/abs/2509.13232

🌀New work: Era of Real-World Human Interaction 🌀 📝: arxiv.org/abs/2509.25137 - RL *directly* from User Conversations - Organic replies + long-term history are learning signal - Trained on WildChat, beats RLHF at *user* level -> the future for personal Super Intelligence? 🧵1/6
After the crazy 极GRPO weekend, let's get rid of the scalar reward or any policy optimization related to it. We explored learning from *verbal feedback* and obtained interesting results:

🚀 Introducing DeepSeek-V3.2-Exp — our latest experimental model! ✨ Built on V3.1-Terminus, it debuts DeepSeek Sparse Attention(DSA) for faster, more efficient training & inference on long context. 👉 Now live on App, Web, and API. 💰 API prices cut by 50%+! 1/n
I don’t often tweet on technical topics but I may have an opposite opinion here…
NO verifiers. NO Tools. Qwen3-4B-Instruct can match DeepSeek-R1 and o3-mini (high) with ONLY test-time scaling. Presenting Recursive Self-Aggregation (RSA) — the strongest test-time scaling method I know of! Then we use aggregation-aware RL to push further!! 📈📈 🧵below!
(1/x) Ever had your #LLM-#RL training mysteriously collapse? 📉 You're not alone. We saw #agentic RL runs fail with exploding #gradients, and found the culprit: a fundamental "training-inference mismatch." Our new #blog post demystifies this vicious cycle.…
😠💢😵💫Tired of endless data collection & fine-tuning every time you try out VLA? Meet RDT2, the first foundation model that zero-shot deploys on any robot arms with unseen scenes, objects & instructions. No collection. No tuning. Just plug and play🚀 Witness a clear sign of…
One thing people rarely mention about research: ideas set the upper bound of your work, but debugging sets the lower bound. Universities teach us how to chase impactful ideas, but they rarely teach us how to debug large, messy ML systems. Here are a few principles I found useful…
This is the command most people should run when using codex-cli codex --search --model=gpt-5-codex -c model_reasoning_effort="high" --sandbox workspace-write -c sandbox_workspace_write.network_access=true
The field of robotics is undergoing a historic revolution right now. I’ve spent the last year thinking about how to mentally model the breakneck progress in robotics + AI. With the help of mascots like “The AGI Bro”, we can try to sift through the noise 🧵
Proud to have been part of the team behind Gaia2 and ARE! ARE = a gym/platform for scaling up LLM agent envs for evals & RL Gaia2 = a new benchmark for hard & practical agent tasks (search, execution, ambiguity, time, noise, & multi-agent) tinyurl.com/aregaia2
Most agent benchmarks assume static, perfect worlds. But real life is asynchronous, noisy, and ambiguous. 🌍 🚀 Meet Gaia2 + ARE: a new benchmark and open-source platform for creating environments and evaluating AI agents in (more) realistic environments.
