Sisif

AI text-to-video with no watermark, at one dollar per five-second clip

About Sisif

Sisif generates short vertical videos from text prompts using an open-weights model running on its own GPUs. Every five-second clip costs one dollar, downloads with no watermark, includes commercial use, and failed renders return your credits, which never expire. It also offers a REST API and an MCP server so agents can order and pay for clips programmatically. It is made for social clips, ads, product videos and faceless channels that want simple per-clip pricing.
