“The goal is to engineer your agents to make the fastest research progress indefinitely and without any of your own involvement.” - Andrej Karpathy, March 2026. My first reaction was: that sounds like a job posting for a system that replaces me. Then I actually ran it. I Have Wasted a Lot of GPU Hours Doing What an Agent Can Do Better I have run hundreds of ML experiments the manual way. Edit a file. Kick off a run. Wait. Check the loss curve. Feel vaguely disappointed. Edit a slightly different file. Repeat until midnight.
