Open-Sora 2.0 Review — HPC-AI Tech's $200K Open-Source Video Model That Matches Commercial Giants

Open-Sora 2.0 (HPC-AI Tech, March 2025) trained an 11B-parameter video generation model for ~$200,000 — matching HunyuanVideo (11B) and Step-Video (30B) on VBench while releasing full weights, training code, and data pipeline under Apache 2.0. Reducing the VBench gap with OpenAI's Sora from 4.52% to 0.69%, it's the most cost-efficient open-source video model of its size class. High VRAM requirements (52–60GB) and a 768px resolution ceiling limit practical deployment. No MCP server. Rating 3/5.
