InfiniteTalk Multi

What is InfiniteTalk?

InfiniteTalk creates videos with accurate lip sync while matching head, face, and body movements to the audio. It maintains identity across unlimited-length videos and also allows image-to-video creation, transforming static photos into lively speaking or singing videos.

Why it looks great

  • Accurate lip synchronization: aligns lip motion precisely with audio, preserving natural rhythm and pronunciation.

  • Full-body coherence: captures head movements, facial expressions, and posture changes beyond the lips.

  • Identity preservation: maintains consistent facial identity and visual style across frames.

  • Image-to-video capability: turns static photos into realistic speaking or singing videos.

  • Instruction following: accepts text prompts to control scene, pose, or behavior while syncing to audio.

Pricing

Output ResolutionCost per 5 secondsMax Length
480p$0.1510 minutes
720p$0.3010 minutes

Billing Rules

  • Standard Rate: $0.03 per second
  • HD (720p) Rate: $0.06 per second (Double the Standard Rate)
  • Minimum Charge: All videos are billed for a minimum of 5 seconds (costing at least $0.15).
  • Billing Cap: To keep your costs predictable, billing is capped at 600 seconds (10 minutes).

How to Use

  1. Upload the left and right audio files.
  2. Upload your image (The image should clearly show two people).
  3. Select the speaking order (left to right, right to left, or meanwhile).
  4. Select the resolution (480p or 720p).
  5. Write the prompt if needed.
  6. Submit the job and download the results once they're ready.

Note

  • Max clip length per job: up to 10 minutes

  • Processing speed: approximately 10–30 seconds of wall time per 1 second of video (varies by resolution and queue load)

Infinitetalk Multi API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/wavespeed-ai/infinitetalk/multi with your input as JSON. The endpoint returns a prediction id. Start polling the result endpoint around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. On completed, read output values from data.outputs. Examples for Infinitetalk Multi below.

HTTP example
set -euo pipefail

Infinitetalk Multi API — Frequently asked questions

What is the Infinitetalk Multi API?

Infinitetalk Multi is a WaveSpeedAI model for talking-avatar generation, exposed as a REST API on WaveSpeedAI. InfiniteTalk Multi converts a single image and two audio inputs into multi-character talking or singing videos at up to 720p. 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 Infinitetalk Multi 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 result endpoint starting around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. The playground generates production-oriented Python, JavaScript, and cURL examples with timeouts, transient-error handling, and safe GET retries. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/wavespeed-ai/infinitetalk-multi.

How much does Infinitetalk Multi cost per run?

Infinitetalk Multi starts at $0.15 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 Infinitetalk Multi accept?

Key inputs: `prompt`, `image`, `resolution`, `seed`, `left_audio`, `order`. 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/wavespeed-ai/infinitetalk-multi.

How long does Infinitetalk Multi take to generate?

Median end-to-end generation time on WaveSpeedAI is around 458 seconds per request, based on recent successful runs. Queue time varies with global demand; live status is visible in the prediction record.

Can I use Infinitetalk Multi outputs commercially?

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