An AI agent just beat NVIDIA's FlashMLA baseline by 9.8% on B200, without seeing its source code

Reddit r/LocalLLaMA ↗ · 2026-11-02

OpenBMB's ForgeKernel agent autonomously optimized a GPU kernel against NVIDIA's FlashMLA black-box baseline over 22 hours, achieving a 9.8% speedup on B200, and is open-sourcing 27 optimized operators along with the ForgeKernel harness.

@FinanceYF5: AMD is trying to bypass NVIDIA’s CUDA moat by pouring in resources. It is committing substantial engineering and compute resources to vLLM. This will benefit the entire ecosystem, including NVIDIA, but the returns for the two companies are not symmetric. Its software stack is still in its early stages, so it is more eager to see inference decoupled from specific hardware.…
