Create AI avatars and talking head videos via [inference.sh](https://inference.sh) CLI.

![AI Avatar & Talking Head Videos](https://cloud.inference.sh/app/files/u/4mg21r6ta37mpaz6ktzwtt8krr/01kg0tszs96s0n8z5gy8y5mbg7.jpeg)

## Quick Start

```bash
curl -fsSL https://cli.inference.sh | sh && infsh login

# Create avatar video from image + audio
infsh app run bytedance/omnihuman-1-5 --input '{
  "image_url": "https://portrait.jpg",
  "audio_url": "https://speech.mp3"
}'
```

> **Install note:** The [install script](https://cli.inference.sh) only detects your OS/architecture, downloads the matching binary from `dist.inference.sh`, and verifies its SHA-256 checksum. No elevated permissions or background processes. [Manual install & verification](https://dist.inference.sh/cli/checksums.txt) available.

## Available Models

| Model | App ID | Best For |
|-------|--------|----------|
| OmniHuman 1.5 | `bytedance/omnihuman-1-5` | Multi-character, best quality |
| OmniHuman 1.0 | `bytedance/omnihuman-1-0` | Single character |
| Fabric 1.0 | `falai/fabric-1-0` | Image talks with lipsync |
| PixVerse Lipsync | `falai/pixverse-lipsync` | Highly realistic |

## Search Avatar Apps
