What changed
Auto quality. The quality parameter on grok-imagine-image-2.0 now accepts auto, and the default when quality is omitted has moved from medium to auto. Auto currently uses low for image generation and medium for image editing. Images are billed at the quality they are served at. Pass low or medium explicitly to pin a specific quality. See Image Generation. Five reference images. Image editing now accepts up to 5 source images per request (was 3). See Multi-Image Editing. New aspect ratios. Image generation and editing accept 21:9 (cinematic widescreen) and 5:2 (wide banners). See Image Generation.
