InfiniteYou AI Face Swap

Overview

InfiniteYou is a state-of-the-art AI face swapping model powered by advanced zero-shot identity preservation technology. Built on FLUX architecture, it delivers high-quality, realistic face swaps while maintaining facial identity characteristics from reference photos.

Features

  • High-Quality Face Swapping: Exchange facial identity between source and target images with exceptional realism
  • Zero-Shot Learning: No training required - works immediately with any face
  • Identity Preservation: Maintains facial features and expressions accurately
  • Fast Processing: Optimized for quick inference with no cold starts
  • Production Ready: Reliable REST API with consistent performance

Input Parameters

Required

  • source_image: URL of the source face image to extract identity from. This should be a clear photo of the face you want to use.
  • target_image: URL of the target image where the face will be swapped. The face in this image will be replaced with the source face.

Optional

  • seed (integer, default: -1): Random seed for reproducibility. Use -1 for random generation, or specify a fixed value for consistent results.

Output

  • Returns an array of URLs pointing to the generated face-swapped images. Each output maintains the pose, lighting, and composition of the target image while replacing the face with the source identity.

Best Practices

  1. Source Image: Use clear, well-lit photos with the face clearly visible and facing forward for best results
  2. Target Image: Ensure the target face is also clear and at a similar angle to the source for optimal swapping
  3. Image Quality: Higher resolution images (1024x1024 or larger) produce better results
  4. Seed Control: Use fixed seed values when you need reproducible results

Pricing

  • Fixed price per generation: $0.03 USD

Use Cases

  • Entertainment and creative content
  • Photo editing and enhancement
  • Avatar creation
  • Character design and visualization

Infinite You API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/wavespeed-ai/infinite-you 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 Infinite You below.

HTTP example

Infinite You API — Frequently asked questions

What is the Infinite You API?

Infinite You is a WaveSpeedAI model for AI inference, exposed as a REST API on WaveSpeedAI. InfiniteYou AI Face Swap - High-quality face swapping powered by zero-shot identity preservation technology. Ready-to-use REST inference API, best performance, no cold starts, affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Infinite You 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/infinite-you.

How much does Infinite You cost per run?

Infinite You starts at $0.050 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 Infinite You accept?

Key inputs: `source_image`, `target_image`. 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/infinite-you.

How long does Infinite You take to generate?

Median end-to-end generation time on WaveSpeedAI is around 46 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 Infinite You 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.
