Qu est-ce que Grok Imagine ?
Grok Imagine is xAI's flagship video model and the cheapest video option on FlyAIgh — 2 credits per second, or 10 credits for a 5-second clip. The Free tier's 15 credits cover a full 6-second Grok Imagine clip plus change.
Despite the entry-level price point, Grok Imagine is a full flagship: native synchronized audio, both text-to-video and image-to-video modes, 6–15 second clip lengths in 1-second increments, and five aspect ratios (16:9, 9:16, 1:1, 2:3, 3:2). Output is 720p.
Grok Imagine's strength is naturalistic motion — physically plausible movement, believable inertia, smooth camera tracking — and a relaxed, slightly cinematic aesthetic that works well for everyday content. It is weaker than VEO 3.1 Quality for fine textural detail and weaker than Sora 2 Pro for indoor photorealism, but for the price it punches well above its weight.
Typical use cases: high-volume social content, A/B test concepts where you'll generate dozens of variants, storyboard animatics, mood board iteration, and any context where cost-per-clip matters more than ultimate visual fidelity. If you're spending a lot on other video models, swap your iteration phase to Grok Imagine and reserve the budget for final hero shots on Sora 2 Pro or VEO 3.1 Quality.
On FlyAIgh, Grok Imagine ships under the same credit wallet as every other model. No separate xAI subscription, no API key — just credits.
