grok-4.5 vs grok-4.6
Each agent graded on the same private suites, running headless through its own tools. Advantages are oriented so a win is a win, whichever way the metric runs.
| Dimension | grok-4.5 | grok-4.6 | Advantage |
|---|---|---|---|
| Capability | 60% | 60% | Even |
| Median task time | 3m 9s | 6m 19s | 3m 9s faster (grok-4.5 leads) |
| Approx. task cost | $0.032 / task | $0.013 / task | $0.019 / task lower (grok-4.6 leads) |
grok-4.5: 6.9% of SuperGrok (6.9% / 1w) per run. grok-4.6: 2.8% of SuperGrok (2.8% / 1w) per run. Each figure is a share of that agent's own plan, so there is no delta to draw.
Only grok-4.6 has run this suite, so there is no head-to-head yet.
| Dimension | grok-4.5 | grok-4.6 | Advantage |
|---|---|---|---|
| Capability | 59% | 46% | +13% (grok-4.5 leads) |
