Grok 4.7 pricing
It is the #12 most expensive of 37 current text models priced per 1M input tokens.
Independent benchmark results
Scores come from independent evaluators that ran the model themselves, pinned to a dated snapshot. Rank is among current models in the same snapshot. xAI's own launch figures are listed under strengths with the publisher named, because they are not measured the same way.

Strengths, cautions and best uses
Strengths
- Holds Grok 4.6's $2 / $6 rates and 500,000-token context window
- Output at $6 per million undercuts every frontier-tier model here except the explicit budget tiers
Cautions
- The long-prompt threshold is 200,000 tokens, the lowest of any model here, and reaching it doubles input and output for the entire request
- xAI's model page does not state a maximum output for Grok 4.7, so it is recorded as unknown rather than inferred
- That page does not explicitly list image input for this model either, so it is catalogued as text-only
Best for
- Output-heavy generation under the 200,000-token prompt line
- A cheaper alternative to the frontier tiers where 500k of context is enough
