核心要点 (BLUF)： Describe the picture in words and get a PNG/JPEG file: model versions, size, aspect ratio and quality are chosen in the form.
Describe the scene, character, style and composition. Versions: Seedream (v4/v5), Banana (plain and Pro), Chat Image (2 and 2.5 with quality levels). Size — a preset or exact pixels.
The image also works as input for Photo → 3D: generate a view and turn it straight into a model.
The price depends on the model, size and quality: base models are 5 tokens per 1K image, Banana Pro is 15–20, quality levels high/xhigh/max start from 20. The exact sum is always shown before the start; failures return tokens.
The tariff prices models and quality levels differently: Seedream and Banana are cheaper, Banana Pro and the high+ tiers cost more.
Yes: choose the «transparent» background with Chat Image 2.5 and PNG output.
