Bring your own PyTorch job. Let an agent speed it up end to end.

🛠️ We built /who-ate-my-flops, a Claude Code / Codex plugin for iteratively optimizing training and inference jobs as a whole—not just individual GPU kernels.

✅ Performance PRs developed with it have been merged into FunASR, FastVideo, gsplat, Ultralytics, Unsloth, and SGLang, with speedups up to 3.6× on the tested workloads.

📝 experiments, profiles, and lessons learned (Blog):

Yesterday, I was giving an intro talk to our dept's new PhD students. Technical things aside, my number 1 suggestion has remained the same over the years: Treat your PhD like a job.

- Avoid 1.5h lunch and three tea breaks.
- Avoid gossiping and loitering at work.
- Lab at 9 am and leave at 6 pm. Being productive till 11 pm in the lab is a lie people till themselves when their day starts at 1 PM.

Everything worth doing can be done with high intensity focus during work hours. And having fun in life is the secret to being productive in a marathon.
