About
We present Open-Sora, an initiative dedicated to efficiently produce high-quality video and make the model, tools and contents accessible to all. By embracing open-source principles, Open-Sora not only democratizes access to advanced video generation techniques, but also offers a streamlined and user-friendly platform that simplifies the complexities of video production. With Open-Sora, we aim to inspire innovation, creativity, and inclusivity in the realm of content creation.
More details can be founded at Open-Sora GitHub.
You can launch this video generation with this model in a Gradio application.
# git clone Open-Sora
git clone https://github.com/hpcaitech/Open-Sora.git
cd Open-Sora
# launch gradio
python scripts/demo.py --model-type v1-HQ-16x256x256
If you want to use this STDiT model in code,
from transformers import AutoModel
stdit = AutoModel.from_pretrained("hpcai-tech/OpenSora-STDiT-v1-HQ-16x256x256")
Do note that this model alone cannot generate video, it should work alongside a vae model and a text encoder model like how we did in the demo.

Using it via the API
Once AxForge deploys opensora-std-hq-16x256x256 for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (opensora-std-hq-16x256x256 below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/embeddings \
-H "Authorization: Bearer $AXFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"opensora-std-hq-16x256x256","input":"text to embed"}'
