Grok Imagine 2.0 Areas

How much does image generation cost?+
Prices depend on the model and resolution. Nano Banana 2.1: — to — cr. Nano Banana Pro: — to — cr. Z-Image: — cr. SeDream T2I: from — cr. Flux 2 Pro: from — cr. GPT Image 1.5: from — cr. Background removal: — cr.
Can I upload my own images?+
Yes, you can upload your own images to the Gallery for free. Uploaded images can serve as a base for editing, upscaling, or background removal.
Can I change just part of a photo?+
Yes — use mask editing in Qwen-Image 2.1. Upload a single photo, click “Draw a mask” and paint the spot you need with a brush or a rectangle, or upload a ready-made mask (white means change). Zoom in with the mouse wheel or two fingers for small details. The model redraws only the painted area. You get two variants to choose from: the full photo, where everything outside the mask comes from your original without losing resolution (up to 3072 px on the long side), and the frame exactly as the model returned it. Price — from — credits.
How do I remove an unwanted object from a photo or replace a caption?+
Paint a mask over the object, a passer-by or the caption with a small margin and describe what should be in that spot and what the background there looks like — for example, “the wooden floor and wall continuing seamlessly” or “the word "Open" in the same font on the same background”. Only the painted area is redrawn; the rest of the image stays unchanged.
How long are images stored?+
Images are stored for 30 days after creation. After that they are automatically deleted. We recommend downloading finished images right after generation.
Which image formats are supported?+
PNG and JPG are supported. You can choose the format during generation. For uploads, JPG, PNG, and WebP are supported.
How do Flux 2 Pro and GPT Image 1.5 differ?+
Flux 2 Pro excels at rendering text in images and supports 1K/2K resolutions. GPT Image 1.5 from OpenAI follows instructions precisely and supports up to 16 reference images in edit mode. Both offer Text-to-Image and Image Edit modes.
What is Grok Imagine in the Gallery?+
Grok Imagine is xAI's image-generation model (creators of Grok). It generates 2 variants per request. Supports Text-to-Image and Image-to-Image (editing). Generated images can be used for video generation in Spicy mode (available only for Grok images).
What is Reframe?+
Reframe changes an image's aspect ratio with AI: the model paints in the missing edges itself, for example turning 1:1 into 16:9. The gallery offers four models: Sixio Reframe extends the frame without touching the original and accepts a suggestion about what to fill in; Luma Photon Reframe needs no prompt and handles panoramic 21:9 and 9:21; Smart Reframe preserves the subject's pose, composition and perspective; Ideogram V3 Reframe lets you pick a render mode and supports every format, including 4:5 and 5:4.
How do Crisp Upscale and SeedVR2 Upscale differ?+
Recraft Crisp Upscale preserves the original's detail and sharpness — best for illustrations and graphics. SeedVR2 Upscale enlarges 2x or 4x, restores detail and removes noise and compression artifacts — best for photos and realistic images.
What happens if generation fails?+
Credits are automatically refunded to your balance on any generation error. You won't lose credits if the model could not create an image.
Can I generate images for free?+
Yes! Sixio offers three free models: Flux 2 Klein and Flux 1 Schnell from Black Forest Labs and SDXL Lightning from ByteDance. They don't spend credits: one shared daily limit of free images covers all three, and the remaining count is shown on their cards. Flux 2 Klein gives the best quality and 5 aspect ratios, Flux 1 Schnell is ultra-fast for prototyping, and SDXL Lightning is quick for illustrations and stylization. The limit refreshes daily.
