FAQPage Schema
How do I generate images using the Gemini API?▼

Image generation with the Gemini API converts text prompts into high-quality images with configurable aspect ratios and resolutions. Use the gemini-imagegen skill with a text description to create variations for marketing, branding, or design work. Requires a GEMINI_API_KEY and supports gemini-3-pro-image-preview or gemini-2.5-flash-image models.

Can I edit and refine existing images with Gemini?▼

Yes. Image editing and refinement with Gemini allows you to modify existing images or compose multiple references through guided prompts. Iterate on outputs using multi-turn chat-like interactions until you reach your desired result for logos, social media visuals, or product mockups.

What does it take to start generating images with Gemini API?▼

To start, you need a GEMINI_API_KEY for authentication, the google-genai dependency to interface with Gemini's models, and Pillow for image handling. The skill supports flexible aspect_ratio and image_size options for both gemini-3-pro-image-preview and gemini-2.5-flash-image models.

What are the limitations of AI image generation with Gemini?▼

Output quality depends on prompt clarity and model capability. Gemini API has rate limits and usage quotas tied to your API key. Complex or highly specific design requests may require multiple refinement iterations, and some creative constraints apply based on Gemini's content policies.

How does multi-turn refinement improve image outputs?▼

Multi-turn refinement enables iterative chat-like prompting where you guide Gemini toward your vision through successive adjustments. Each interaction refines the previous output, letting you specify style tweaks, composition changes, or element modifications without regenerating from scratch.
