Frequently asked questions
How much does Grok 4.6 cost per 1M tokens?
Grok 4.6 costs $2.00 per million input tokens and $6.00 per million output tokens at xAI Grok list prices. Output is 3.0x the input rate, so the input:output ratio of your workload drives the real cost more than the headline price.
Does Grok 4.6 support prompt caching?
Yes. Cached input is billed at $0.500 per million tokens, 4x cheaper than uncached input. There is no cache-write premium, so caching is never a net loss.
What is the batch discount for Grok 4.6?
Grok 4.6 does not offer a batch pricing tier.
What is Grok 4.6's context window?
500K tokens of context with up to 33K output tokens per request. A larger context window raises the ceiling on what you can send, not the price per token, but filling it on every request is one of the most common causes of an unexpected bill.
