What the tiers mean

"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 level 3 of 5 (partial at levels 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.

12 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.

Run on grok-cli grok 0.2.101 (5bc4b5dfad), model grok-4.6 (--reasoning-effort high), week 2026-W33.

One run of this suite consumes 15.6% of SuperGrok.

How the plan cost was measured

Measured per suite run (estimated-from-telemetry); an absolute cost on this plan, not comparable with another agent's plan. Measured in a declared quiet window on a shared subscription: operator SuperGrok login shared between eb-runner and the claude host; graded runs only inside the scheduled quiet window, all recurring tasks blocked for its duration.

Run on grok-cli grok 0.2.101 (5bc4b5dfad), model grok-4.6 (--reasoning-effort high), week 2026-W33.

One good solve on this suite consumes 1.4% of SuperGrok on average.

How the plan cost was measured

Counted over each issue's first solve (5 solves); the walk's failed harder cells and confirmation runs are the benchmark's own search cost and are excluded (full walk: 15.3% over 13 cells). Measured per cell run (estimated-from-telemetry); an absolute cost on this plan, not comparable with another agent's plan. Measured in a declared quiet window on a shared subscription: operator SuperGrok login shared between eb-runner and the claude host; graded runs only inside the scheduled quiet window, all recurring tasks blocked for its duration.

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 →

Frequently asked questions

Is grok-4.6 worth it on SuperGrok?

On our private real-world suite (real-world@v3), grok-4.6 earned grade C with 58% capability, clearing every problem up to tier 1 of 5 - a localized single-file bug and landing some tier 5 problems. It runs on SuperGrok at $30/month (public price as of 2026-07-20). One full suite run consumed 15.6% of the plan's week window. Measured 2026-08-13.

How good is grok-4.6 at real-world coding?

grok-4.6 clears tier 1 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 58% (grade C). Last benchmarked 2026-08-13.
