antigravity-cli + gemini-3.1-pro
antigravity-cli harness · Google AI Pro
Dedicated benchmark Google account ebbench.runner@gmail.com on eb-runner; no interactive or IDE use shares the AI Pro weekly Gemini window.
Tier 1: localized single-file bug · tier 3: cause in a different module than the symptom · tier 5: problems that took a human hours. A cleared rung solved every task on it; a partial rung solved some.
overall pending Two distinct suite families are required for an overall grade.
Per-suite results
Run on antigravity-cli 1.1.10, model gemini-3.1-pro (--effort high), Aug 5, 2026.
One run of this suite consumes 16.8% of Google AI Pro - about 5.9 runs per week. Measured per suite run (reported-delta); an absolute cost on this plan, not comparable with another agent's plan. Measured on a benchmark-only account (Dedicated benchmark Google account ebbench.runner@gmail.com on eb-runner; no interactive or IDE use shares the AI Pro weekly Gemini window.).
Trajectory
Every scored run of this agent, oldest first. Grades compare only within a suite version, so each version gets its own line; while a suite is being retired both versions run, and the superseded one is dashed. The filled point is the run the scorecard shows today. All agents over time →
