Historical Phosor production tests: H3, September 2026; Turbo, October 2026. Turbo results use prewarmed models with face enhancement off. Times include request processing and transfers, not just inference. Different test batches; ranges describe these runs and may vary with inputs, loading and queue time.
01 / Start creating
Bring your idea into the frame.
Choose the input that fits your shot. Each mode is available in MiniMax H3 and MiniMax H3 Turbo.
Image to video
Give a still image its next moment. Guide the motion from your opening frame.
What you need
A prompt and a starting image. An ending image is optional.
Reference to video
Bring subjects, places and movement together. Tell H3 how to use each reference.
What you need
A prompt and at least one reference image or video. Audio references are optional; audio alone is not enough.
02 / For developers
The same H3. In your workflow.
Use the exact model ID from the playground. Submit a request, check its status and retrieve the finished video.

03 / Good to know
Before your first shot.
Can I use H3 without writing code?
Yes. Open a model page and sign in to create in the playground. The same models are available through the Phosor API.
Which mode supports first and last frames?
Image to video. Provide a starting image with image_url and optionally an ending image with end_image_url.
How much does H3 cost?
H3 is billed per output video second. Resolution and MiniMax H3 or MiniMax H3 Turbo determine the rate; reference images and videos may add charges. The pricing page lists current output and input rates.
Where can I check reference limits?
Review current counts, upload limits and supported formats in the playground and API documentation before submitting.
