Plain text, OpenAI Chat or Responses JSON, or Anthropic Messages JSON. A final assistant message or a response body counts as output. Counted in your browser; nothing is uploaded.

Counts use OpenAI's o200k tokenizer, so they are exact for GPT-6 and GPT-5 models, plus a few tokens of message framing. Other providers' tokenizers count the same text differently and do not publish a conversion factor; Anthropic says Claude models from 4.7 on produce about 30% more tokens than earlier Claude models. For an exact count on another model, paste one of its API responses: the usage it reports is shown above.

How the Grok 4.7 API Cost Calculator works

As of October 13, 2026, Grok 4.7 costs $2 per million input tokens and $6 per million output tokens, with cache hits at $0.50. A request costs its input tokens × the input rate ÷ 1,000,000 plus its output tokens × the output rate ÷ 1,000,000; multiply by requests for the monthly bill.

cost = (fresh input × input rate + cached input × cache rate + (output + reasoning) × output rate) ÷ 1,000,000

This page uses the same method as the LLM API Cost Calculator, which explains each term and assumption in full.

Worked example

A chat feature on Grok 4.7 sending 3,000 input tokens and getting 500 back, 1,000 times a day.

  1. 1Input: 3,000 × $2 ÷ 1,000,000 = $0.006
  2. 2Output: 500 × $6 ÷ 1,000,000 = $0.003
  3. 3Per request: $0.009
  4. 4Per month: $0.009 × 1,000 × 30 = $270.00

$270.00 a month. Caching a fixed system prompt that makes up 80% of the input would bring it to about $162.00, and the batch API would halve either figure.

Frequently asked questions

How much does Grok 4.7 cost per million tokens?

$2 per million input tokens and $6 per million output tokens at xAI's standard rate. Cache hits are $0.50, and writing to the cache costs no more than ordinary input. There is no batch discount. Prompts over 200,000 tokens are billed at $4 input and $12 output for the whole request.

Why can Grok 4.7 cost more than Claude or GPT on cached work?

Its cache hits are dear. Grok 4.7 charges $0.50 per million cached tokens, a quarter of its input rate, where Claude Sonnet 5.5 charges $0.10 and GPT-6 Sol $0.20. Its output is cheap at $6 against their $10, so it wins on output-heavy work and loses on large cached prompts. xAI also takes no Batch API requests for Grok 4.7.

How big a request can Grok 4.7 take?

Up to 500,000 tokens of context, input and output together, though xAI publishes no separate limit on output. That is roughly 380,000 words of English. The calculator warns when a request will not fit.
