You Jiacheng(@YouJiacheng):Last week, I directed K3 to optimize mjwarp kernels for a workload and got 77% speedup. Today I asked GPT-6 Astra to optimize it further. It first tried an obviously wrong direction and failed. Then it tuned num_threads and got 0.38% speedup.😅 It's pretty good on other tasks.
