Agent-Generated GPU Kernels Outperform FlashAttention
AccBalanced · x · 2026-07-14
The post claims that PyPTX is now the 最快 FlashAttention kernel they have benchmarked.
Key details include:
- Testing was conducted using an improved PyPTX harness.
- A multi-day agent loop allowed GPT 5.6 Sol Max to automatically generate the kernel.
- Performance is claimed to 超过 FlashAttention-4 和 cuDNN.
- The author predicts that future kernel authoring will become 100% agentic, writing directly down to the ISA layer.
Essentially, models are no longer just writing high-level code; even underlying GPU kernels are being taken over by agents.
