Compare real-time generation costs for FLUX 3 Max, Seedance 2.5, MiniMax H3, Google Veo 3.1, and Kling. Calculate per-second rendering expenses with active promotional discounts and countdown timers.
Most modern AI video models hosted on serverless platforms like fal.ai bill strictly on a pay-as-you-go, per-second basis for the generated video output. For instance, FLUX 3 Max (720p) and MiniMax H3 charge a fixed price per second of rendered footage. ByteDance's Seedance 2.5 uses latent video tokens scaled to resolution and duration (approximating ~$0.4730/s at 720p 24fps). There are no mandatory monthly subscriptions, credit expirations, or minimum seat fees.
Through November 7, 2026, Black Forest Labs and fal.ai offer a 75% launch discount on FLUX 3 Max 720p generations. The rate is reduced from the standard $0.1700 per second down to $0.0425 per second. Once the promotional deadline passes, pricing automatically reverts to standard rates. This calculator dynamically tracks the remaining days and adjusts calculations automatically.
We strictly uphold data integrity by only presenting pricing directly verified on official model rate cards. While various third-party blogs speculate on FLUX 3 Max 1080p upscaling costs, fal.ai has not yet published an official dedicated rate card for native 1080p inference on this endpoint. Unverified figures are excluded rather than presented as official facts.
For FLUX 3 Max, synchronized audio generation is generated natively in the latent space and is included at no additional surcharge. Furthermore, fal.ai endpoints bill purely by output duration in seconds rather than total rendered frames. Whether you configure 24 FPS or 30 FPS, the duration in seconds determines the generation fee.
During the promotional window, FLUX 3 Max (720p at $0.0425/s) is the most budget-friendly frontier option. Once standard pricing resumes, MiniMax H3 (768p at $0.0800/s) offers the lowest sustained unit cost, while Seedance 2.5 ($0.4730/s) caters to complex multi-subject interactions and director-level camera transitions with native audio.
