+# Replicate
+
+Read when the user picks `--provider replicate`. Replicate support is intentionally scoped to model families baoyu-image-gen can validate locally and save without dropping outputs.
+
+## Supported Families
+
+**`google/nano-banana*`** (default: `google/nano-banana-2`)
+
+- Supports prompt-only and reference-image generation
+- Uses Replicate `aspect_ratio`, `resolution`, and `output_format`
+- `--size <WxH>` is accepted only as a shorthand for a documented `aspect_ratio` plus `1K` / `2K`
+
+**`bytedance/seedream-4.5`**
+
+- Supports prompt-only and reference-image generation
+- Uses Replicate `size`, `aspect_ratio`, and `image_input`
+- Local validation blocks unsupported `1K` requests before the API call
+
+**`bytedance/seedream-5-lite`**
+
+- Supports prompt-only and reference-image generation
+- Uses Replicate `size`, `aspect_ratio`, and `image_input`
+- Local validation currently accepts `2K` / `3K` only
+
+**`wan-video/wan-2.7-image`**
+
+- Supports prompt-only and reference-image generation
+- Uses Replicate `size` and `images`
+- Max output is 2K
+
+**`wan-video/wan-2.7-image-pro`**
+
+- Supports prompt-only and reference-image generation
+- Uses Replicate `size` and `images`
+- 4K is allowed only for text-to-image; local validation blocks `4K + --ref`
+
+## Guardrails
+
+- Replicate currently supports only single-output save semantics in this tool — keep `--n 1`
+- If a model is outside the compatibility list above, baoyu-image-gen treats it as prompt-only and rejects advanced local options instead of guessing a nano-banana-style schema

+## Examples
+
+```bash
+# Default model
+${BUN_X} {baseDir}/scripts/main.ts --prompt "A cat" --image out.png --provider replicate
+
+# Explicit model
+${BUN_X} {baseDir}/scripts/main.ts --prompt "A cat" --image out.png --provider replicate --model google/nano-banana
+```
