GRPO makes reasoning model yap a lot, but there's a simple fix: Sample more responses during training, and train on the shortest ones. This creates a length pressure that makes the model sound much more terse, without sacrificing accuracy!! Examples of GRPO vs GFPO versions…

2026+: everyone releases their own OS Building with Claude Code SDK made me realize that we are just a UI away from the next ChatGPT moment. Models are more intelligent than they seem. AI Agents are already unlocking unique and novel experiences. Claude Code is the…
What happens if you compare LMs on SWE-bench without the fancy scaffolds? Our new leaderboard “SWE-bench (bash only)” shows you which LMs are the best at getting the job done with just bash. More on why this is important 👇
🗒️Have been exploring Agent-RL training over the past few months, particularly in GUI scenarios. Here’s a summary of some practical insights and lessons 🤔 learned from the perspective of an industry researcher, and some reference papers.
Slides for my lecture “LLM Reasoning” at Stanford CS 25: dennyzhou.github.io/LLM-Reasoning-… Key points: 1. Reasoning in LLMs simply means generating a sequence of intermediate tokens before producing the final answer. Whether this resembles human reasoning is irrelevant. The crucial…

Rubrics as Rewards: Reinforcement Learning Beyond Verifiable Domains 'We introduce Rubrics as Rewards (RaR), a framework that uses structured, checklist-style rubrics as interpretable reward signals for on-policy training with GRPO. Our best RaR method yields up to a relative…

Evaluating agents on benchmarks is a pain. Each benchmark comes with its own harness, scoring scripts, and environments and integrating can take days. We're introducing the Terminal-Bench dataset registry to solve this problem. Think of it as the npm of agent benchmarks. Now…
Scaling up RL is all the rage right now, I had a chat with a friend about it yesterday. I'm fairly certain RL will continue to yield more intermediate gains, but I also don't expect it to be the full story. RL is basically "hey this happened to go well (/poorly), let me slightly…
We built 200k-GPU clusters; We scaled up & curated higher-quality data; We scaled compute by 100x; We developed training & test-time recipes; We made everything RL native; We stabilized infrastructure and speeded up; That's how you turn RL into the pre-training scale. Yet I am…

🚀 Introducing 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. 💪DeepSWE…
I suggest a new metric: Pass@1/K. For a given "K" You only get a point if all "K" attempts were successful. So it's a continuation of the Pass@K graph to the left hand site and intuitively measures robustness / confidence.
