Check pricing and billing
1. Do not assume generation is free
Free availability depends on the model and plan. Do not assume Google Cloud welcome or trial credits cover Gemini API image generation.
2. Check your project billing
Review the connected project plan, billing status and limits in Google AI Studio. Creating a key alone does not guarantee free access or image-generation availability.
3. Billing
Costs depend on the model, image size, request and exchange rate. There is no guaranteed fixed KRW price. Check Google pricing and billing documentation before requesting images.
