claude-code + claude-haiku-4-5: 17.0% of Claude Max 5x per run, about 5.9 runs per 5h. grok-cli + grok-4.5: 8.0% of SuperGrok per run, about 12.5 runs per week. Each figure is a share of that agent's own plan, so there is no delta to draw.
Grades and deltas are comparable only within a suite version. See methodology.
