VAPI Image Gen

Generate images via VAPI's OpenAI-compatible Images API (/images/generations).

Basic Usage

python3 {baseDir}/scripts/gen.py --prompt "your prompt here"

Options

# Specify model (default: nano-banana-pro)
python3 {baseDir}/scripts/gen.py --prompt "..." --model nano-banana-pro

# Higher resolution (append -2k or -4k to model name)
python3 {baseDir}/scripts/gen.py --prompt "..." --model nano-banana-pro-2k

# Save image locally (default: NO save, URL only)
python3 {baseDir}/scripts/gen.py --prompt "..." --save

# Save to OSS directory (~/.openclaw/oss/)
python3 {baseDir}/scripts/gen.py --prompt "..." --oss

# Save to custom directory
python3 {baseDir}/scripts/gen.py --prompt "..." --save --out-dir /path/to/dir

# Aspect ratio
python3 {baseDir}/scripts/gen.py --prompt "..." --aspect-ratio 16:9

# Image count
python3 {baseDir}/scripts/gen.py --prompt "..." --count 2

Supported Models

nano-banana series (returns URL, fast):

  • nano-banana
  • nano-banana-pro ← default
  • nano-banana-2
  • nano-banana-pro-2k / nano-banana-pro-4k (high res)

gpt-image series (returns base64, always saved):

  • gpt-image-1
  • gpt-image-1.5

Config

Set in .env or ~/.openclaw/openclaw.json:

  • VAPI_API_KEY — your VAPI API key (required)
  • VAPI_BASE_URL — base URL with /v1 suffix (required); defaults to https://api.v3.cm/v1 if not set

Save Behavior

  • Default: no local file, output MEDIA:<url> directly
  • --save: save to ~/.openclaw/media/
  • --oss: save to ~/.openclaw/oss/
  • gpt-image models always save to media/ (API returns base64 only)
