Quick post-summer GSO update. Several new models are now live on the leaderboard!! 🧵👇
Interested in building and benchmarking deep research systems? Excited to introduce DeepScholar-Bench, a live benchmark for generative research synthesis, from our team at Stanford and Berkeley! 🏆Live Leaderboard guestrin-lab.github.io/deepscholar-le… 📚 Paper: arxiv.org/abs/2508.20033 🛠️…
MoE layers can be really slow. When training our coding models @cursor_ai, they ate up 27–53% of training time. So we completely rebuilt it at the kernel level and transitioned to MXFP8. The result: 3.5x faster MoE layer and 1.5x end-to-end training speedup. We believe our…
new post. there's a lot in it. i suggest you check it out
After three intense months of hard work with the team, we made it! We hope this release can help drive the progress of Coding Agents. Looking forward to seeing Qwen3-Coder continue creating new possibilities across the digital world!

We just released the evaluation of LLMs on the 2025 IMO on MathArena! Gemini scores best, but is still unlikely to achieve the bronze medal with its 31% score (13/42). 🧵(1/4)

It's easy to confuse Best@K vs Pass@K—and we've seen some misconceptions about our results. Our 59% on SWEBench-Verified is Pass@1 with Best@16, not Pass@8/16. Our Pass@8/16 is 67%/71%. So how did we achieve this? DeepSWE generates N candidate solutions. Then, another LLM…

RLVR is not just about RL, it's more about VR! Particularly for LLM coding, good verifiers (tests) are hard to get! In our latest work, we ask 3 questions: How good are current tests? How do we get better tests? How much does test quality matter? leililab.github.io/HardTests/
Questions to ask 1. can we see a "commit history?" (only 2 commits in repo) 2. what level of supervision was provided? 3. the paper is 4 dense pages. was it outlined first in a lean friendly way and then formalization took place? 4. which models were used in the formalization?

Day 3 of drilling down into popular benchmarks for models/agents. Benchmark #3: LiveCodeBench Developed by researchers at UC Berkeley, MIT, and Cornell, this benchmark evaluates LLM code-generation skills and continually expands with new problems drawn from programming contests…
Introducing Code Researcher - a deep research agent for large systems code and commit history. aka.ms/coderesearcher Achieves a 58% crash resolution rate on a benchmark of crashes in the Linux kernel, a complex codebase with 28M LOC & 75K files.
Ensuring construct validity is becoming increasingly more complex as we move towards more real-world evaluation setups. We should routinely inspect benchmark solutions to ensure intended goal is being met!!
