Grok 4.7

xAI’s frontier model with a 500K context

ProprietaryReleased: September 21, 2026ValueVerified: October 24, 2026

What it is

xAI’s frontier model for coding, agentic tasks and knowledge work: a 500,000-token context, text and image input, no stated output limit, and reasoning from low to xhigh.

NLT take

A credible third option for agentic coding with a 500K window and one of the simplest price sheets here. Worth an eval if you want a non-Anthropic, non-OpenAI default.

Before you switch

Prompts at or above 200K tokens double the price ($4/$12). The 500K window is not a flat-price window.

Cost for a real task

The same task on every model: 50,000 input tokens and 10,000 output tokens, at the base tier.

Task cost

$0.16

50K input + 10K output tokens

Prompts under 200K tokens. At 200K or more: $4 input / $12 output for the whole request.
