grok-cli + grok-4.6
grok-cli harness · SuperGrok ($30/mo)
Clears tier 1 of 5 (partial at tiers 2 and 5) on Real-world issues
Capability mean across 2 graded suite families.
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.
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.
Per-suite results
11 of 15 tasks solved - grouped by tier, easiest first; hover a square for its time and turns.
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.
23 of 25 tasks solved (12 credited without running) - each row is one bug, vaguest report first and context growing to the right; hover a square for its time and turns.
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 →
Dotted = a new model version took the line over (grok-4.5 → grok-4.6): the points either side were graded by different models. Plan or settings re-registrations join solid.

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.
