What a job costs on each
1,000 runs of each job at the two list prices. The gap moves from job to job because the models price input, output and cached context differently.

|---|---|---|---|
| Support reply3,000 in, 400 out. | $10.00 | $8.40 | Grok 4.7, 16% less |

The token counts are ours, chosen to look like real work; the prices are the makers’. A model with no published cache price bills the agent task’s repeated context at its full input rate.
