Runway bills its Dev API in credits ($1 = 100): Gen-4.5 costs 12 credits/sec ($0.12/sec) and Gen-4 Turbo 5 credits/sec ($0.05/sec). The rate does not change with resolution — the series is not tiered by output quality, which is exactly where it diverges from the domestic models. There, resolution costs money; here, only seconds do.
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.
