AutoHelix: Open-Source Agent Optimization Loop Boosts Qwen3-4B GSM8K from 41% to 93%

The author details AutoHelix's design: external verification and budgeted iteration. External verification ensures every change passes constraints and metrics; budgeted iteration keeps the agent trying within a fixed budget, preventing premature giving up. On Qwen3-4B, GSM8K accuracy rose from 41% to 93% at a cost of $64; on AlgoTune, median speedup across 154 tasks reached 8.5x.
