Sora is shutting down. Move to a full visual agent.
OpenAI closed the Sora app on April 26, 2026 and retires the Sora API on September 24, 2026. Hedra Agent and Workspaces plan, generate and edit across the leading video models, on GPU infrastructure Hedra runs itself, with post-training for teams that need a model of their own.

} }'A more modern way to work
Skip the model aggregators. Hedra Agent and Workspaces give your team an autonomous agent that supercharges your workflows with a superintelligent understanding of the latest models: brief it in a shared space and it plans, generates, and edits across video, image, speech, and music, with your team and your agents working alongside it.
GPU infrastructure, an inference engine, and post-training research
Hedra operates GPU clusters and the inference engine that runs diffusion and autoregressive media models on them 8x faster. The same research team post-trains models for customers: supervised fine-tuning, LoRA training, and GRPO, on your data.
Hedra and Sora: focus at a glance
Sora was one lab's video model and app, now being retired. Hedra is the infrastructure and research company that serves every lab's models and trains yours.
| Dimension | Hedra | Sora |
|---|---|---|
| What it is | GPU infrastructure, inference and post-training research | OpenAI's video app and API, being retired |
| Core technology | Hedra's inference engine, its own GPU clusters, and post-training (SFT, LoRA, GRPO) | Sora 2 and Sora 2 Pro |
| Models | Open-weight models on Hedra's engine, models post-trained for you, and partner models through a gateway | Its own models; app closed April 26, 2026, API closes September 24, 2026 |
| How you connect | API, SDK, CLI, MCP, and Hedra Workspaces | Sora app and API, until shutdown |
| Where inference runs | Hedra's GPU clusters, or your own | OpenAI's cloud |
| Best fit | Teams building visual products who need inference, capacity and custom models | Teams that need a migration path |
Where Sora workloads go: video models on Hedra infrastructure
Rates per second of generated video at the resolution shown. Open-weight models run on Hedra's engine; partner models are reached through the gateway.

FAQs
- What is happening to Sora?
- OpenAI announced on March 24, 2026 that it is shutting Sora down. The web and mobile app closed on April 26, 2026, and the Sora API is retired on September 24, 2026. OpenAI has told users to export their videos before the cutoff.
- Is Sora 2 Pro still available on Hedra?
- Sora 2 Pro is OpenAI's model, reached through Hedra's gateway only while OpenAI's API is live. It leaves the catalog when the API closes on September 24, 2026. Move production to one of the models above before then; the request shape is the same, only the model id changes.
- Can Hedra post-train a model for us?
- Yes. Hedra runs supervised fine-tuning, LoRA training, and GRPO on models you own or license, on your data and against your evals, then serves the result on the same engine. The weights are yours.
