xAI's video API: Grok Imagine 1.5 from $0.08/sec and the Lite build at $0.02/sec — the cheapest row in the overseas layer. Native 1080p with sound and lip-sync included, priced per second in xAI's own docs, plumbed into the X platform and fast; a cheap way to generate draft footage at volume before switching to pricier tiers for finals.
Google, Runway, Luma, xAI and Pika all publish a per-second list price. Google retired the Veo 3.1 preview line on 2026-10-22 in favour of Gemini Omni, so those dead tiers are gone. Figures here come from each vendor’s own pricing page (checked 2026-11); the CNY column uses the PBoC mid rate, not a platform retail mark-up. Subscription-only tools (Midjourney, Adobe Firefly) and the retired Sora 2 API are not listed.
