This is the second image guide. The first covers Nano Banana, GPT Image, FLUX and Grok. Here are the models from ByteDance, Alibaba (Qwen and Wan) and Topaz Labs.
ByteDance: Seedream
- Seedream 4.5 goes up to 4K, edits from several images and keeps dense text accurate.
- Seedream 5 Lite generates up to 3K, edits from several images and is strong on product shots.
- Seedream 5 Pro is for photorealistic 1K and 2K pictures, multi-image edits and AI layer decomposition.
Qwen
Qwen has the two cheapest image models on SonnaLabs.
- Qwen Z-Image is ultra-affordable and fast, for photorealistic text to image.
- Qwen Image generates and edits, and follows the prompt closely.
- Qwen 2 Image is accurate with prompts, renders text and edits images.
- Qwen 3 Image edits from up to 3 reference images and produces crisp 1K and 2K pictures.
- Qwen 3 Pro is studio-grade 1K and 2K photorealism with advanced multi-image editing.
Wan
- Wan 2.7 Image is the next generation of Tongyi Wanxiang, with 1K to 4K generation and multi-image edits from up to 9 references.
- Wan 2.7 Image Pro is the flagship, with better prompt adherence and studio 4K detail.
Topaz: upscaling
Topaz Image Upscale does not draw anything new. It enhances the resolution of a picture you give it, up to 8×, and keeps the detail.

How to choose
- Tight budget or many drafts: Qwen Z-Image, then Qwen Image.
- Product pictures: Seedream 5 Lite.
- Many reference images: Wan 2.7 Image accepts up to 9; Qwen 3 Image up to 3.
- A picture that is nearly right but too small: run it through Topaz Image Upscale at 2× or 4×.
Image generation needs a paid plan or credit packs; see how credits work.
