Seedream 4.5
Seedream 4.5 text-to-image and image-to-image. Provide a prompt; pass image_list with one or more reference images to run image-to-image.
Resolution is determined by ratio (aspect) + image_size (tier); all tiers are billed the same.
Pricing: 1.85 tokens per image (= $0.037).
Returns an img_uuid; poll GET /api/v1/jobs/detail (or use custom_callback_url) to get the generated image.
