Lewis Tunstall Shares Large Open Experiment on Autonomous Agents Iterating on NanoGPT Research

Lewis Tunstall shares a quoted post from Elie Bakouch describing what they call the largest open experiment on autonomous agents iterating on a research environment, scaling runtime, compute, models, and harnesses.

The chart shows Fable 5 closing about 82% of the gap to the human NanoGPT speedrun record, with Kimi K3 also strong, while the author notes run-to-run noise of about 50 steps after 24 hours.

Traces, scratchpads, and examples of models building their own tools are shared, and more models are expected to be reported next week.
