Full specs, context window and API limits →How much does Grok 4.6 cost per million tokens?
Grok 4.6 costs $2.00 per million input tokens and $6.00 per million output tokens ($3.00/M blended at 3:1). A cutting-edge flagship model combining deep analytical reasoning with live real-time web and social knowledge synthesis. Verified 2026-09-08.
How much does Grok 4.6 cost per 1,000 requests?
Computed from generated token pricing. Each row assumes the listed input and output tokens per request; this model has no measured verbosity factor, so the unadjusted output estimate is shown.
| Request shape | Input tokens | Output tokens | Cost / 1,000 requests |
|---|---|---|---|
| Short | 100 | 50 | $0.5000 |
| Medium | 1,000 | 500 | $5.0000 |
| Long | 4,000 | 2,000 | $20.0000 |
Formula: ((input price × input tokens) + (output price × output tokens × verbosity factor)) ÷ 1,000,000 × 1,000. Assumptions: short 100/50, medium 1,000/500, long 4,000/2,000 input/output tokens per request. Unadjusted — no measured verbosity factor is available.
