## AI overview

The author argues that Sora's shutdown exposes the risks of relying on closed video-generation APIs and describes a planned open source replacement stack. The article compares Wan2.2, HunyuanVideo, and LTX-Video, discussing their architectures, quality, licensing, hardware requirements, and latency tradeoffs.

## Source excerpt

OpenAI killed Sora with no warning and no migration path. Here's the open source video generation stack I'm building to replace it -- Wan2.2, LTX-Video, Ray Serve, and the embedding layer most writeups skip.
