# Gemini Image Gen

Generate and edit images via SkillBoss API Hub using pure Python stdlib. Supports standard generation + editing, high-quality generation, batch runs, and an HTML gallery output.

## Quick Start

```bash
export SKILLBOSS_API_KEY="your-key-here"

# Default: 4 random prompts
python3 scripts/gen.py

# Custom prompt
python3 scripts/gen.py --prompt "a cyberpunk cat riding a neon motorcycle through Tokyo at night"

# High-quality engine
python3 scripts/gen.py --engine imagen --count 4 --aspect 16:9

# Edit an existing image (gemini engine only)
python3 scripts/gen.py --edit path/to/image.png --prompt "change the background to a sunset beach"

# Use a style preset
python3 scripts/gen.py --style watercolor --prompt "floating islands above a calm sea"

# List available styles
python3 scripts/gen.py --styles
```

## Style Presets

| `photo` | Ultra-detailed photorealistic photography, 8K resolution, sharp focus |
| `anime` | High-quality anime illustration, Studio Ghibli inspired, vibrant colors |

## Full CLI Reference

| Flag | Default | Description |

| `--prompt` | (random) | Text prompt. Omit for random creative prompts |
| `--count` | 4 | Number of images to generate |
| `--engine` | gemini | Engine: `gemini` (supports edit) or `imagen` (high-quality). Both routed via SkillBoss API Hub |
| `--model` | (auto) | Model hint (informational; SkillBoss auto-routes to the best model) |
| `--edit` | | Path to input image for editing (gemini engine only) |
| `--aspect` | 1:1 | Aspect ratio for imagen: `1:1`, `16:9`, `9:16`, `4:3`, `3:4` |

## Python Example

```python
import subprocess

subprocess.run(
    [
        "python3",
        "scripts/gen.py",
        "--prompt",
        "a serene mountain landscape at golden hour",
        "--count",
        "4",
        "--style",
        "photo",
    ],
    check=True,
)
```

## Troubleshooting

- Missing API key: set `SKILLBOSS_API_KEY` in your environment and retry.
- Rate limits / 429 errors: wait a bit and retry, reduce `--count`, or switch engines.
- Model errors: SkillBoss API Hub auto-routes to the best available model; retry or adjust `--engine`.
