Image Generation
Content & CreativeTestedAI image generation and editing — create from scratch or modify reference images with optional branding. Choose your model: Nano Banana 2 (Google) or gpt-image-2 (OpenAI).
OVERVIEW
Image Generation is a two-mode service. Pick your model in setup — Nano Banana 2 (Google) or gpt-image-2 (OpenAI) — bring your own API key, and switch between them anytime. In create mode, describe the visual you need — a hero banner, social graphic, ad creative, infographic, or product shot — and Agentcy builds an optimized structured prompt that produces the best results. In modify mode, provide one or more reference images and describe what you want changed — swap an outfit, change a background, restyle the image — and the AI applies your modifications while preserving the original subject.
Brand colors, fonts, and logo are opt-in. They are only applied when you explicitly ask for branded content (e.g., "use my brand colors", "add my logo"). Having a domain does not automatically trigger branding. The service works with or without a domain — for general images, just describe what you want.
Generated images are available in 1K, 2K, or 4K resolution across multiple aspect ratios (1:1 for social, 16:9 for banners, 9:16 for stories, and more). Images are stored temporarily for 30 days and returned as downloadable URLs.

TIPS
4Brand colors and logo are only applied when you explicitly ask — having a domain does not auto-trigger branding
In modify mode, describe what to CHANGE, not what the image already shows — the AI can see the reference
Image generation costs are on your own API usage (Gemini or OpenAI, depending on your chosen model) — not included in the Agentcy subscription
AI text rendering in images can be imperfect — keep text overlays simple (1-2 lines)
