tokevenGrok 4.5
Grok 4.5 is Grok's most capable model, priced at $2.00/MTok input and $6.00/MTok output with a 500K context window. Same list price as Grok 4.6 but a cheaper cached rate ($0.30/MTok vs $0.50), so cache-heavy workloads are cheaper here than on 4.6. xAI publishes release notes at month granularity only; dated to the start of the month.

Monthly cost projections
Projected monthly spend at different call volumes, using code generation as a representative workload (2,000 input / 4,000 output tokens per call).
| Calls / month | Without caching | With caching (85% read discount) |
|---|---|---|
| 1K | $28 | $25.62 |
| 10K | $280 | $256.2 |
| 100K | $2,800 | $2,562 |
| 500K | $14,000 | $12,810 |
| 1M | $28,000 | $25,620 |
Caching estimate assumes 70% of input tokens are cache reads. Your actual cache hit rate will depend on prompt structure and reuse.
