Imagine image-quality slug retires November 2, 2026
The grok-imagine-image-quality slug keeps resolving after November 2, but it is served as grok-imagine-image-2.0 with quality forced to low. Pin 2.0 and quality yourself if you care about look or cost. grok-imagine-image (1.0) is unchanged. grok-imagine-image-pro already follows quality, then follows this redirect.
Floor rule. Hero stills: grok-imagine-image-2.0 + quality medium. Cheap iterate: grok-imagine-image (1.0) or 2.0 low. Do not ride the retired slug.
Consumer Quality Mode on grok.com is grok-imagine-image-2.0 — not the retiring API slug grok-imagine-image-quality.
Notice September 2, 2026 · effective November 2, 2026
Are these draft rates?
No. Table amounts are published developer API list prices from xAI’s public docs — not temporary or unofficial “draft” rate cards.
“Standard still” means the cheaper 1.0 image model (grok-imagine-image) for iteration. Hero plates use grok-imagine-image-2.0 with quality: "medium" — not the retiring image-quality slug, and not that the dollars were provisional.
Published developer API list prices — not “draft” rate cards. Confirm on docs.x.ai before you budget. Image-quality slug retires November 2, 2026.

Budget tips for Studio work
Iterate on grok-imagine-image (1.0, list $0.02). Hero plates on grok-imagine-image-2.0 with quality: "medium". Cost-match the old quality look with 2.0 low — not the retiring slug.
A 6s 1.5 clip at 720p (~$0.84 list) costs more than forty 1.0 stills — lock DNA and plates first. 1.5 1080p is $0.25/s.
