Grok 4.7
xAI's current flagship for coding and knowledge work: $2 / $6 per million tokens, 500K context, same price and speed as Grok 4.6.
What it is
Grok 4.7 was announced on September 21, 2026 as the most capable model from xAI (which now brands itself SpaceXAI in its documentation). It keeps Grok 4.6's list price of $2 input and $6 output per million tokens with a 500K context window, and xAI claims it is twice as fast at half the price of comparable frontier models. It is a reasoning model with image input and is sold through the xAI API, Cursor, Grok Build and third-party routers.
Pricing
| Input | $2.00 |
| Output | $6.00 |
| Cached input (cache read) | $0.500 |
| Cache write | not published |
| Batch input | not published |
| Batch output | not published |
| Fast / priority input | $4.00 |
| Fast / priority output | $12.00 |
- Long context (>=200K prompt tokens): $4 input, $1 cached input, $12 output, applied to every token in the request.
- Fast variant: twice the output speed at twice the token price (1.5x for long-context requests); xAI says it is available only in Cursor and Grok Build, not on the public API.
- Batch API is not supported for this model as of October 8, 2026.
- Server-side tools (web search, X search) are billed per call on top of tokens.
Capability highlights
- xAI calls it its most capable model and recommends it for code and chat (vendor claim).
- Positioned as twice as fast at half the price of comparable models (vendor claim).
- Function calling and structured outputs supported; Batch API not supported.
- Rate limits published at 150 requests per second and 50M tokens per minute.
Modalities: text, image → text. Reasoning model; effort low, medium, high (default), xhigh. Responses API always returns encrypted reasoning content. Requests with 200K or more prompt tokens are billed at the long-context rate for the whole request.
How to use it
API: xAI API model ID grok-4.7 (Responses API and Chat Completions). Served from US regional endpoints.
