# Seedream — AI Image Generation & Editing by ByteDance

Generate and edit AI images using ByteDance's Seedream — featuring text-to-image generation, image editing, and batch sequential generation across 3 model generations.

Seedream v5.0 Lite is the latest flagship model with enhanced quality, typography excellence, poster design capabilities, PNG output support, and built-in prompt optimization (Standard/Fast modes). It supports up to 4K resolution with 16 preset sizes and can process up to 14 reference images for editing.

> **Data usage note**: This skill sends text prompts and image URLs to the Atlas Cloud API (`api.atlascloud.ai`) for image generation and editing. No data is stored locally beyond the downloaded output files. API usage incurs charges per image based on the model selected.

## Setup

1. Sign up at https://www.atlascloud.ai
2. Console → API Keys → Create new key
3. Set env: `export ATLASCLOUD_API_KEY="your-key"`

The API key is tied to your Atlas Cloud account and its pay-as-you-go balance. All usage is billed to this account. Atlas Cloud does not currently support scoped keys — the key grants access to all models available on your account.

---

## Script Usage

This skill includes a Python script for image generation. Zero external dependencies required.

### List available image models

```bash
python scripts/generate_image.py list-models
```

### Generate an image

```bash
python scripts/generate_image.py generate \
  --model "MODEL_ID" \
  --prompt "Your prompt here" \
  --output ./output
```

### Upload a local image (for editing)

```bash
python scripts/generate_image.py upload ./local-image.jpg
```

### Edit an image

```bash
python scripts/generate_image.py generate \
  --model "MODEL_ID" \
  --prompt "Edit instruction" \
  --image "https://...uploaded-url..."
```

Run `python scripts/generate_image.py generate --help` for all options. Extra model params can be passed as key=value (e.g. `aspect_ratio=16:9 resolution=2k`).

## Workflow: Submit → Poll → Download

### Text-to-Image Example (v5.0 Lite)

```bash
# Step 1: Submit
curl -s -X POST "https://api.atlascloud.ai/api/v1/model/generateImage" \
  -H "Authorization: Bearer $ATLASCLOUD_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "bytedance/seedream-v5.0-lite",
    "prompt": "A minimalist Japanese-style poster for a tea ceremony, elegant typography, zen garden background, warm earth tones",
    "size": "2304*4096",
    "output_format": "png"
  }'
# Returns: { "code": 200, "data": { "id": "prediction-id" } }

# Step 2: Poll (every 3 seconds, typically completes in 2-3s)
curl -s "https://api.atlascloud.ai/api/v1/model/prediction/{prediction-id}" \
  -H "Authorization: Bearer $ATLASCLOUD_API_KEY"
# Returns: { "code": 200, "data": { "status": "completed", "outputs": ["https://...image-url..."] } }

# Step 3: Download
curl -o output.png "IMAGE_URL_FROM_OUTPUTS"
```

### Image Editing Example (v5.0 Lite)

```bash
curl -s -X POST "https://api.atlascloud.ai/api/v1/model/generateImage" \
  -H "Authorization: Bearer $ATLASCLOUD_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "bytedance/seedream-v5.0-lite/edit",
    "prompt": "Change the background to a sunset beach scene, keep the person unchanged",
    "images": ["https://example.com/photo.jpg"],
    "size": "2304*1728",
    "output_format": "jpeg"
  }'
```

### Batch Sequential Example (v5.0 Lite)

```bash
curl -s -X POST "https://api.atlascloud.ai/api/v1/model/generateImage" \
  -H "Authorization: Bearer $ATLASCLOUD_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "bytedance/seedream-v5.0-lite/sequential",
    "prompt": "A series of product photos for a coffee brand: latte art, espresso close-up, coffee beans, packaging design",
    "size": "2048*2048",
    "max_images": 4,
    "output_format": "jpeg"
  }'
# Returns multiple images in outputs array
```

### Batch Sequential Editing Example

```bash
curl -s -X POST "https://api.atlascloud.ai/api/v1/model/generateImage" \
  -H "Authorization: Bearer $ATLASCLOUD_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "bytedance/seedream-v5.0-lite/edit-sequential",
    "prompt": "Apply a warm vintage film filter, slightly desaturated with golden highlights",
    "images": ["https://example.com/photo1.jpg", "https://example.com/photo2.jpg", "https://example.com/photo3.jpg"],
    "max_images": 3,
    "output_format": "jpeg"
  }'
```

### Polling Logic

- `processing` / `starting` → wait 3s, retry (typically takes 2-3s for single image)
- `completed` / `succeeded` → done, get URL(s) from `data.outputs[]`
- `failed` → error, read `data.error`

### Atlas Cloud MCP Tools (if available)

If the Atlas Cloud MCP server is configured, use built-in tools:

```
atlas_generate_image(model="bytedance/seedream-v5.0-lite", params={...})
atlas_get_prediction(prediction_id="...")
```

## Implementation Guide

1. **Determine task type**:
   - Text-to-image: user describes what they want to generate
   - Image editing: user provides existing image(s) and describes modifications
   - Batch sequential: user needs multiple related images in one go
   - Batch sequential editing: user needs consistent edits across multiple images

2. **Choose model version**:
   - **v5.0 Lite** (recommended): Best quality, typography, PNG support, prompt optimization
   - **v4.5**: Strong alternative with poster/brand design focus
   - **v4**: Budget option at $0.024/image

3. **Choose single vs sequential**:
   - **Single**: One image per request (default)
   - **Sequential**: Up to 15 related images per request — ideal for product series, storyboards, brand asset sets

4. **Extract parameters**:
   - Prompt: be descriptive about style, composition, colors, typography if needed
   - Size: pick from 16 presets; consider aspect ratio (portrait/landscape/square/ultrawide)
   - Output format: PNG for transparency or lossless, JPEG for smaller files
   - Prompt optimization: Standard for best quality, Fast for speed

5. **Execute**: POST to generateImage API → poll prediction → download

6. **Present result**: show file path, display image if possible

## Prompt Tips

Seedream produces excellent results especially for:

- **Typography & Text**: "A poster with bold title 'SPRING SALE' in elegant serif font, floral frame..."
- **Poster Design**: "Movie poster for a sci-fi thriller, dark blue tones, futuristic cityscape..."
- **Brand Visuals**: "Product packaging design for organic tea brand, minimalist, earth tones..."
- **Multi-reference Editing**: Provide multiple reference images for consistent style transfer
- **Batch Series**: Use sequential mode for "A 4-panel comic strip..." or "Product photos from 4 angles..."
