xAI ships Grok 4.6 at $2 input and $6 output per 1M tokens, which is the cheapest output rate of any current frontier model, alongside Grok Build for coding and the Imagine line for images and video. Context runs 500K on 4.6 and 1M on the 4.20 family.

Two features define the offer: configurable reasoning depth, so you pay for deliberation only when it helps, and native access to live web and X search as billed tools. Long-context requests cross a threshold at 200K tokens, after which every token in the request bills at the higher rate.

Cheapest frontier output$6 per 1M against $25 to $50 at the other labs.
Live X and web searchGrounding against a social corpus no competitor has.
Threshold pricingAbove 200K tokens the whole request bills at the higher tier.

How to choose

  • Keep requests under 200K tokens where possible; crossing it reprices the entire request.
  • Use configurable reasoning rather than switching models when tasks vary in difficulty.
  • Budget X and web search separately — they are billed per thousand calls.
  • Compare Grok 4.6 output pricing against the other flagships; it is materially lower.

Common mistakes

Ignoring the thresholdOne long request at 210K tokens bills every token at the higher rate.
Using the general model for codeGrok Build is cheaper and purpose-built.

Who this suits
