Usage

• Add node “Ad Creative Generator” and configure:
  • Product Name, Target Audience, optional Landing URL, Tone
  • Copy Provider: OpenAI or Google Gemini
    • OpenAI Copy: choose model (e.g., gpt-4o-mini), set Max Tokens, Temperature, Top P, Presence/Frequency penalties
    • Gemini Copy: choose model (e.g., gemini-1.5-flash), set Max Output Tokens, Temperature, Top P, Top K, and Safety thresholds
  • Image Provider: OpenAI, Google Gemini, or None
    • OpenAI Images: model (e.g., dall-e-3), Size (256x256 … 1792x1024), Quality (standard/hd), Style (natural/vivid), Background (default/transparent)

Notes

• OpenAI (DALL·E 3) supports n=1; the node loops requests if you ask for multiple images.
• For Meta publishing, typically upload images to obtain image_hash before creating ad creatives.
• Google Ads API requires OAuth2 and developer token for real publishing.
