# Z-Image > Z-Image is a 6-billion-parameter open image model family from Alibaba's Tongyi Lab, built on a single-stream diffusion transformer. Z-Image-Turbo arrived in November 2025 and Z-Image in January 2026, with open weights. On Kenerate, Z Image Base costs 3 credits, renders up to 2048 px, and remixes one uploaded image with a strength slider — in our test, higher strength changed more of the image.

Open Z Image Base — Pick it in /app/image. Any credit pack unlocks it. 2. Write the prompt — Plain sentences work; say “photorealistic” for photos. 3. Remix an image (optional) — Upload one image and set Reference strength in Advanced settings — lower keeps more. 4. Download — Up to 2048 px, no watermark. ## In depth ### What makes Z-Image different Most large image models use two streams for text and image. Z-Image uses a single-stream diffusion transformer at 6 billion parameters, which keeps it small enough for 16 GB consumer GPUs while producing photoreal results [1]. ### When to pick Z Image Base Pick it for cheap photoreal drafts and for image-to-image where you want control over how much changes. For polished finals switch to Seedream 5.0 Pro; for text-heavy designs, GPT Image 2. References: [1] Tongyi-MAI — Z-Image (GitHub): https://github.com/Tongyi-MAI/Z-Image ## FAQ Q: What is Z-Image? A: An open 6-billion-parameter image model family from Alibaba's Tongyi Lab. Z-Image-Turbo was released in November 2025 and Z-Image in January 2026. Q: How much does Z-Image cost on Kenerate? A: Z Image Base is 3 credits an image — about 3.5¢ on the $15 pack. Q: Is Z-Image open source? A: Yes, Tongyi Lab released the weights under Apache 2.0.
