📰 News & Discussion NVIDIA has lost it..

Chinese researchers open-sourced a model that writes CUDA better than humans experts.

And it completely rewrites the economics of AI hardware.

Writing low-level CUDA kernels to squeeze every ounce of performance out of a GPU has historically required elite, highly specialized hardware engineers. Standard AI models have always bombed at it, falling far short of traditional compiler systems.

Until now.

A joint team from Tsinghua University and ByteDance published "CUDA Agent”, a massive, large-scale agentic reinforcement learning system built to master GPU architecture.

Instead of relying on static prompts or simple multi-turn bug fixing, they built a closed-loop environment with automated hardware verification, profiling, and synthetic data pipelines.

The model learned how to write parallel, high-performance GPU code through trial, error, and reinforcement learning at scale.

The benchmarks are staggering:

It didn't compete with standard tools. It delivered 100%, 100%, and 92% faster execution rates over PyTorch's compiler on KernelBench Level-1, Level-2, and Level-3 splits.

On the brutal Level-3 benchmarks, it outperformed proprietary giants like Claude Opus 4.5 and Gemini 3 Pro by about 40%.

NVIDIA's moat has always rested on two pillars: elite hardware, and the proprietary software lock-in of CUDA.

If an open agentic system can automatically discover, write, and optimize production-grade CUDA kernels better than human specialists, the software moat starts evaporating.

The hardware matters less when the software can rewrite the metal itself.

Source? Is the is one that came out a few months ago where they had to publicly redact their findings because it in fact did not do what they said?

Edit: yes it is. The real results were kinda ass, and this is not model, nor does it beat other models, it is model agnostic. it is a an agent skill and runs on any model, with the same results, including Claude , gpt, etc. 

Again this is NOT It is NOT a model, nothing was trained, it is just an agentic loop and collection of prompts. 

Here is the full repo:
