Open-Sora 2.0: Training a Commercial-Level Video Generation Model in $200k

Understand

Video generation models have achieved remarkable progress in the past year.

• The quality of AI video continues to improve, but at the cost of larger model size, increased data quantity, and greater demand for training compute.
• In this report, we present Open-Sora 2.0, a commercial-level video generation model trained for only $200k.
• With this model, we demonstrate that the cost of training a top-performing video generation model is highly controllable.
