Grok Imagine API FAQ
- How much does the Grok Imagine API cost?
- On Unifically, Grok Imagine images cost $0.01 (speed model) or $0.025 (2.0 quality model) each. Video costs $0.04 per second at 480p, $0.07 at 720p, or $0.125 at 1080p. Upscaling a video is a flat $0.05. Billing is per generation with no subscription; live rates are on the pricing page.
- Which Grok Imagine model should I use?
- Use Grok Imagine 2.0 Image for final-quality images and 1.0 Image for $0.01 drafts. For video, 1.5 Video Fast is the flexible route with text-to-video, references, and clips up to 30 seconds, while 1.5 Video is the official image-to-video build and the only route that reaches 1080p.
- What is the difference between Grok Imagine 1.5 Video and 1.5 Video Fast?
- Both run Grok Imagine 1.5. The 1.5 Video route is the official API build: image-to-video only, 1–15 seconds, up to 1080p. The Fast build trades a small amount of quality for speed and adds text-to-video, up to 7 reference images, style presets, and 1–30 second clips at 480p or 720p. Only Fast tasks can be extended or upscaled.
- Can I use Grok Imagine online without coding?
- Yes. Every Grok Imagine model on Unifically has a browser playground: type a prompt, adjust settings like duration and resolution, and generate. No code or SDK is required, and there is no subscription — each generation is billed at the same pay-per-use rate as the API.
- Is Grok Imagine free to try?
- Yes. New accounts start with $0.20 of free balance — enough for 20 images on the 1.0 speed model or 8 on Grok Imagine 2.0. After that you top up and pay per generation, with no subscription or credit expiry.
- Is Grok Imagine still free on X?
- No. xAI restricted free Grok Imagine generation in January 2026 and moved it fully behind a paid subscription in March 2026. The API route here needs no X or Grok subscription: new Unifically accounts start with $0.20 of free balance, then pay per generation at the rates above.
- Do I need an X or Grok subscription to use the API?
- No. Unifically is pay-per-use: you top up a balance and each generation deducts its exact cost. There is no monthly fee, seat license, or credit expiry.
