micro1 scaled its agent eval infra 12x in five months, rollouts in 12s

Exp_Mark · x · 2026-11-12

micro1 published a postmortem-style article on scaling and optimizing its evaluation and RL-environment infrastructure: 12x monthly token volume across 3x as many environments in five months, with agent rollouts starting in 12 seconds instead of three minutes.

A single request now carries an evaluation from setup through execution and grading, with the service handling recovery, coverage tracking, and reporting anything unmeasurable. The article also covers subtler agent-eval challenges: detecting runs that look active but have stalled, and catching infrastructure failures that would otherwise distort benchmarks.
