"Clears" marks the highest rung where every task at it and below was solved. 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. The headline stops at the last unbroken rung, so a solved tier above a half-solved one counts only as partial.
Clears no level (partial at levels 1, 2, 3, 4 and 5) on Vibe coding v1 - the vaguest report level at which it still fixed every bug, having also cleared every richer level below

What the levels mean
Level 1: a full brief naming the surface and the acceptance · level 3: the report as filed · level 5: a vague vibe report in a non-technical user's words. Context falls as the level rises, so vaguer is harder. A cleared level fixed every bug at it and below; a partial level fixed some. The headline stops at the last unbroken level, so a fix above a half-cleared level counts only as partial.
3 of this suite's tasks were credited rather than run: on a suite that asks the same problem at several levels of detail, solving it from the vaguest description credits the more detailed ones instead of asking again.
11 of 15 tasks solved - grouped by tier, easiest first; hover a square for its time and turns. solved partial not solved
Run on antigravity-cli 1.1.13, model gemini-3.1-pro (--effort high), week 2026-W34.
One run of this suite consumes 51.2% of Google AI Pro's 5h window and 8.5% of the weekly limit.
How the plan cost was measured
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.).

One run of this suite consumes 4.6% of Google AI Pro's 5h window and 0.8% of the weekly limit.
How the plan cost was measured

Run on antigravity-cli 1.1.13, model gemini-3.1-pro (--effort high), week 2026-W34.
One good solve on this suite consumes, on average, 5.1% of Google AI Pro's 5h window and 0.9% of the weekly limit.
How the plan cost was measured
Counted over each issue's first solve (3 solves); the walk's failed harder cells and confirmation runs are the benchmark's own search cost and are excluded (full walk: 15.0% over 22 cells). Measured per cell 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.).
Task outputs from these runs are withheld: publishing them would reveal the private suite. Per-task scores, times and turns are in the chips above.
Trajectory
One point per grading week - a re-run within a week shows only its latest execution. 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. Click a point or week for plan usage. All agents over time →
On our private real-world suite (real-world@v3), gemini-3.1-pro earned grade D with 53% capability, clearing every problem up to tier 3 of 5 - a problem whose cause sits in a different module than the symptom and landing some tier 5 problems. It runs on Google AI Pro. One full suite run consumed 8.5% of the plan's week window. Measured 2026-08-17.
How good is gemini-3.1-pro at real-world coding?
gemini-3.1-pro clears tier 3 of our five-tier real-world ladder - every task at that tier and below - where tier 1 is a localized single-file bug and tier 5 is a problem that took a human engineer hours. It solves some but not all tasks up at tier 5. Its capability score on real-world@v3 is 53% (grade D). Last benchmarked 2026-08-17.
