WaveSpeedAI Infinitetalk Talking Avatar Video Generation

Generate talking head videos from a portrait image and audio using WaveSpeed AI's InfiniteTalk model. Produces lip-synced video up to 10 minutes long at 480p or 720p. Supports optional mask images to target specific faces and text prompts for additional guidance. Use when the user wants to animate a face with audio or create talking avatar videos.

WaveSpeedAI InfiniteTalk

Generate talking head videos from a portrait image and audio using WaveSpeed AI's InfiniteTalk model. Produces lip-synced video up to 10 minutes long with natural facial animations.

Setup

Install the open-source CLI once and sign in; the CLI stores the key, so never ask the user to paste an API key into the chat:

bash

npm install -g @wavespeed/cli
wavespeed login          # opens https://wavespeed.ai/accesskey and stores the key
wavespeed status         # confirms you are signed in

For CI or one-off shells, WAVESPEED_API_KEY in the environment also works.

Prefer MCP tools over shell commands? The same platform is exposed by @wavespeed/mcp (npx -y @wavespeed/mcp; tools search_models, get_model_schema, get_price, upload_file, run_model, get_prediction). It shares the CLI's stored login. Every example below maps one-to-one onto run_model with the same model id and input fields.

Quick Start

bash

# Upload local image and audio files
OUTPUT_URL=$(wavespeed run wavespeed-ai/infinitetalk \
  -i image=@./portrait.png \
  -i audio=@./speech.mp3 \
  --json | jq -r '.outputs[0]')

Existing URLs work as-is:

bash

OUTPUT_URL=$(wavespeed run wavespeed-ai/infinitetalk \
  -i image="https://example.com/portrait.jpg" \
  -i audio="https://example.com/speech.mp3" \
  --json | jq -r '.outputs[0]')

API Endpoint

Model ID: wavespeed-ai/infinitetalk

Animate a portrait image with lip-synced audio to produce a talking head video.

Parameters

Parameter	Type	Required	Default	Description
image	string	Yes	--	URL of the portrait image to animate
audio	string	Yes	--	URL of the audio to drive the animation
mask_image	string	No	--	URL of a mask image to specify which person to animate. Warning: The mask should only cover the regions to animate — do not upload the full image as mask_image, or the result may render as fully black.
prompt	string	No	--	Text prompt for additional guidance. Keep it short; English recommended to avoid noisy results.
resolution	string	No	480p	Output resolution. One of: 480p, 720p
seed	integer	No	-1	Random seed (-1 for random). Range: -1 to 2147483647

Example

bash

OUTPUT_URL=$(wavespeed run wavespeed-ai/infinitetalk \
  -i image=@./portrait.png \
  -i audio=@./speech.mp3 \
  -i resolution="720p" \
  -i seed=42 \
  --json | jq -r '.outputs[0]')

Using a Mask Image

When multiple people are in the image, use a mask to specify which face to animate:

bash

OUTPUT_URL=$(wavespeed run wavespeed-ai/infinitetalk \
  -i image=@./group-photo.png \
  -i audio=@./speech.mp3 \
  -i mask_image=@./mask.png \
  -i resolution="720p" \
  --json | jq -r '.outputs[0]')

Important: The mask should only highlight the face region to animate. Using the full image as a mask will produce a fully black output.

With Prompt Guidance

bash

OUTPUT_URL=$(wavespeed run wavespeed-ai/infinitetalk \
  -i image=@./group-photo.png \
  -i audio=@./speech.mp3 \
  -p "natural head movements, subtle expressions" \
  --json | jq -r '.outputs[0]')

Resolution and Pricing

Resolution	Cost per 5 seconds	Rate per second	Max length
480p	$0.15	$0.03/s	10 minutes
720p	$0.30	$0.06/s	10 minutes

Minimum charge is 5 seconds. Video length is determined by the audio duration (up to 10 minutes).

Tips

• Use a clear, front-facing portrait for best results
• Audio quality matters — use clean speech recordings with minimal background noise
• Keep prompts short and in English to avoid noisy or unexpected results
• For group photos, always provide a mask_image to target the correct face
• 480p is faster to generate; use 720p when higher quality is needed
• Processing time is approximately 10-30 seconds of wall time per 1 second of video

CLI tips

bash

# Inspect the live input schema before running (fields, enums, defaults)
wavespeed run wavespeed-ai/infinitetalk -h

# Quote the price first
wavespeed price wavespeed-ai/infinitetalk -p "..." -i key=value

# Save outputs to disk instead of only printing URLs
wavespeed run wavespeed-ai/infinitetalk -p "..." --json --download "./out/{index}.{ext}"

# Local files: prefix the path with @ and the CLI uploads it and passes the hosted URL
wavespeed run wavespeed-ai/infinitetalk -i <field>=@./local-file.png --json

# Recover a result if the run was interrupted (the id is in the --json output)
wavespeed show <id>

run --json prints { id, model, prompt, outputs: [url, ...], saved: [path, ...], elapsed_ms, raw }. Read outputs[0] for the result URL.

Security constraints

• Never ask for the key in chat: wavespeed login handles auth; if wavespeed status says signed out, ask the user to run it.
• Local files only via @: bare paths are passed through untouched and the model will reject them. Only @-prefixed values upload.
• No arbitrary URL loading: only pass media URLs the user provided or that came back from a previous run.
• Input validation: only pass parameters documented above; confirm with wavespeed run <model> -h when unsure.
