Gemini 3.1 Flash Lite Image

Image quality, resolution, pricing and editing

Every price below is the official provider price converted at ₹96 per US dollar, and you pay exactly that price. OpenAI image models are billed by the tokens the request actually uses, so Low quality costs far less than Max. Gemini image models are billed per image, and each resolution has its own model ID.

How to use each control

• Resolution (Gemini): pick the model ID — google/gemini-3.1-flash-image (1K), -2k or -4k; same for google/gemini-3-pro-image. Tested: 1K returned 1024×1024, 2K returned 2048×2048, 4K returned 4096×4096. Lite and 2.5 Flash are 1K only.
• Aspect ratio (Gemini 3 Pro / 3.1 Flash): send "image_config": {"aspect_ratio": "16:9"}. Tested: 3.1 Flash 4K at 16:9 returned 5504×3072. Gemini does not accept OpenAI quality, size, format or background fields.
• Editing: POST /v1/images/edits with one image or several image[] files, in order. OpenAI models also accept a PNG mask. Gemini makes one image per request (n=1).
• Charges: you only pay for images actually returned. A failed request is refunded. The exact charge is in the x-tokenbaazar-cost-paise response header.
