GTerm - Small Model Big Bench
Built at Google I/O Hackathon · May 23, 2026 · San Francisco, CA

How high can Gemini 3.5 Flash climb on Terminal-Bench? GTerm is an attempt to answer this question. We believe we can beat SOTA! Early results are promising. How it works: GTerm is running a Meta-Harness-inspired self-improving loop on Flash. The original example in the Meta-Harness paper reached 79.2% with Claude Code + Opus 4.7 improving over ten continuous days of harness evolution. We’re on Day 1 with Flash and started at 37% and are climbing. Smaller model. New loop. Big bench.
