Decoupled agent runtime, mini harnesses: notes on a frontier lab's infra stack
stochasticchasm · x · 2026-09-22
The author shares technical notes on a frontier lab's infrastructure: a decoupled agent runtime/sandbox setup (judged sound), multiple mini harnesses instead of one meta harness (dismissed as implementation fluff), and disaggregated data/control planes (sensible). Also wonders when MOPD will follow mixRL.
