AI Artist - Nano Banana Image Generation

Generate images using 129 curated prompts from awesome-nano-banana-pro-prompts collection. Routes final rendering through ai-multimodal, so the same prompt workflow can use direct Google or OpenRouter-backed Google models.

Validation interview is mandatory (use --skip to bypass).

Workflow

IMPORTANT: Run the validation interview before generating unless --skip is explicitly requested.

Quick Start

python3 scripts/generate.py "<concept>" -o <output.png> [--mode MODE] [--provider PROVIDER]

Generation Modes

Mode	Description
search	Find best matching prompt from 129 curated prompts (default)
creative	Remix elements from top 3 matching prompts
wild	Out-of-the-box creative interpretation (random style transform)
all	Generate all 3 variations

Examples

# Default search mode
python3 scripts/generate.py "tech conference banner" -o banner.png -ar 16:9

# Route through OpenRouter while keeping Nano Banana prompt behavior
python3 scripts/generate.py "tech conference banner" -o banner.png --provider openrouter

# Creative remix (combines multiple prompts)
python3 scripts/generate.py "AI workshop" -o workshop.png --mode creative

# Wild/experimental (random artistic transformation)
python3 scripts/generate.py "product showcase" -o product.png --mode wild

# Generate all 3 variations at once
python3 scripts/generate.py "futuristic city" -o city.png --mode all -v

Options

Flag	Description
-o, --output	Output path (required)
-m, --mode	search, creative, wild, or all
--provider	auto (default), google, or openrouter
-ar, --aspect-ratio	1:1, 16:9, 9:16, etc.
--model	flash2 (default, fast+quality), flash (previous), pro (quality/4K)
-v, --verbose	Show matched prompts and details
--dry-run	Show prompt without generating
--skip	Bypass validation interview

--provider auto will honor IMAGE_GEN_PROVIDER=openrouter when set; otherwise it prefers direct Google unless only OpenRouter credentials are configured.
