The endpoint returns a prediction id; poll the prediction endpoint until status flips to completed, then read the output URL from data.outputs[0]. Examples for Ray 2 Flash I2v below.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/luma/ray-2-flash-i2v" \

Ray 2 Flash I2v API — Frequently asked questions

What is the Ray 2 Flash I2v API?

Ray 2 Flash I2v is a Luma model for video generation from images, exposed as a REST API on WaveSpeedAI. Luma Ray 2 Flash I2V turns images into high-quality videos with advanced prompt optimization and multi-size output options. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Ray 2 Flash I2v API?

POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID; poll the prediction endpoint until status flips to "completed", then read the output URL from the result. The playground generates a ready-to-paste code sample in Python, JavaScript, or cURL for whatever inputs you've set. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/luma/luma-ray-2-flash-i2v.

How much does Ray 2 Flash I2v cost per run?

Ray 2 Flash I2v starts at $0.20 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.

What inputs does Ray 2 Flash I2v accept?

Key inputs: `prompt`, `image`, `duration`, `size`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/luma/luma-ray-2-flash-i2v.

How long does Ray 2 Flash I2v take to generate?

Average end-to-end generation time on WaveSpeedAI is around 59 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.

Can I use Ray 2 Flash I2v outputs commercially?

Commercial usage rights depend on the model's license, set by its provider (Luma). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
