• POST /v1/responses
• POST /v1/messages

Grok Imagine uses POST /v1/images/generations and POST /v1/images/edits. Example identifiers: grok-imagine-image, grok-imagine-image-2.0, grok-imagine-image-quality. Billed per image, not by tokens.

Example Chat Completions identifier: grok-4.6. Query GET /v1/models for the currently admitted list.

Published rates

Chat figures are USD / 1M tokens; image models are USD / image. These are live sale rates (default 70% off, Gemini and GPT-5.6 Luna 20% off, Grok chat 50% off, every image model a flat $0.10; the current discount is the rate shown here), not an upstream invoice. New packs last 30 days; historical cards convert to a permanent USD balance. Cache writes are not part of the public billing claim.

Chat: USD / million tokens. Images: USD / image. Live billable prices, updated automatically; — means unavailable or unsupported.
