FAQ
Which models does HiAPI support?
HiAPI supports selected image, video, and audio generation models, including GPT Image 2.5 Flare and Sunburst. Browse the full list on the models page.
How do persistent artifact links work?
Set storage to persistent and generated outputs are stored for you and returned as durable links in the task result.
Can I use callbacks instead of polling?
Yes. Provide a callback URL and HiAPI notifies you when the task reaches its final state, so you skip polling.
Can I try models before integrating?
Yes. Use the Playground on each model page to explore parameters and example outputs before writing code.
