Rust is a great match for agentic coding because of strong compile-time guarantees of memory and concurrency safety. Tight feedback loop for agents. If it compiles, it has a good chance to work. Exciting!
🎉 CUDA Rust is here! Team 🟩 ❤️ 🦀
You can now write CUDA kernels in plain Rust, two ways: cuda-oxide (SIMT) and cutile-rs (Tile).

NEWS: NVIDIA Groq 3 LPX is now in full production.
NVIDIA Vera Rubin NVL72 is the foundation of every AI factory. Paired with Groq 3 LPX, it unlocks faster, smarter agents and breakthrough user experiences.
Through extreme co-design across seven chips and five purpose-built racks, #NVIDIAVeraRubin is the most extensive AI factory platform.
Read the release ⬇️ nvidianews.nvidia.com/news/n…
The future of AI codegen is to let models evolve their compiler harness, creating & evolving the tools and abstractions for best performance via experimentation. The CAKE work is demonstrating that beautifully - producing SoTA kernels with practical impact. Awesome work team!
🍰 CAKE paper's out, the design bet: the compiler isn't a fixed black box the agent calls — it's part of the harness, and it's under evolution too.
CAKE didn't inherit existing abstraction layer. no tile/layout abstractions: the vocabulary was distilled by agents from a corpus of production kernels. every pattern the agent couldn't express pushed new primitives into the IR, and the analyses to keep them checkable. every barrier/layout bug that kept coming back became a verifier rule.
none of this can be designed up front. the IR has to co-evolve with the kernels, and the workload tells you what's missing, the corpus tells you if the fix broke anything.
the best language for an agent is the one that tells you what's illegal, what's slow, and which decision might made it faster.

That was a great talk @marksaroufim — started MLsys on an exciting note!
My MLSys keynote on AI writing systems code got more interest than I expected. The recording will take a while, so in the finest tradition of AI labs sharing blog posts, we’re starting the Core Automation Blog with this one coreauto.com/blog/when-ai-st…

Today we are releasing our first public beta of Nsight Python! The goal is to simplify the life of a Python developer by proving a pythonic way to analyze your kernel code!
Check it out, provide feedback!
Nsight Python — nsight-python docs.nvidia.com/nsight-pytho…
FlashInfer Bench’s evaluation of kernels with real-world setups will accelerate development of kernels by both humans and agents - so cool! Can’t wait to see the advances that will come out of it.

🤔 Can AI optimize the systems it runs on?
🚀 Introducing FlashInfer-Bench, a workflow that makes AI systems self-improving with agents:
- Standardized signature for LLM serving kernels
- Implement kernels with your preferred language
- Benchmark them against real-world serving workloads
- Fastest kernels get day-0 integrated into production
First-class integration with FlashInfer, SGLang (@lmsysorg ), and vLLM (@vllm_project ) at launch🙌

AMD Instinct MI355X was supposed to compete with NVIDIA Blackwell right?
So much for AMD having an advantage in inference.

We’re thrilled that FlashInfer won a Best Paper Award at MLSys 2025! 🎉
This wouldn’t have been possible without the community — huge thanks to @lmsysorg’s sglang for deep co-design (which is crtical for inference kernel evolution) and stress-testing over the years, and to @vllm_project for integration support.
With continued help from @NVIDIAAIDev , FlashInfer is becoming more stable and faster. Let’s keep building together!
🎉 Congratulations to the FlashInfer team – their technical paper, "FlashInfer: Efficient and Customizable Attention Engine for LLM Inference Serving," just won best paper at #MLSys2025. 🏆
🙌 We are excited to share that we are now backing FlashInfer – a supporter and contributor to the project. We’ve chosen FlashInfer to release our top LLM inference kernels, including those from TensorRT-LLM, making them easy to integrate into @vllm_project, SGLang (@lmsysorg), and custom inference engines.
It started as a collaborative research project at @uwcse, @CarnegieMellon, and OctoAI (acquired by NVIDIA) with the goal of creating a flexible LLM inference kernel library that is engine agnostic, highly optimized, and easy to extend for new techniques such as algorithms for KV cache reuse. It is now a thriving open source project with production deployments and contributions from research and development teams across the AI systems community.
Check out FlashInfer today to get started to see our first Blackwell kernels for DeepSeek MLA available now: nvda.ws/4djKdq7
Congratulations again to Zihao Ye and all authors of the MLSys paper -- Lequn Chen, Wuwei Lin, Yineng Zhang, Stephanie Wang, Baris Kasikci, Arvind Krishnamurthy, Vinod Grover, Tianqi Chen, Ruihang Lai. And thank you to all community contributions, we look forward to continuing to grow this project.
