Creating Images
What AI models does ZSky AI offer for image generation?
ZSky AI offers photorealistic, next-gen AI, and stylized for image generation. The photorealistic mode excels at photorealistic output and accurate text rendering. next-gen AI provides enhanced detail and coherence. stylized offers broad artistic flexibility across many visual styles. You can switch between models freely. Learn more about photorealistic image generation.
What resolutions can I generate images at?
ZSky AI supports a wide range of resolutions and aspect ratios. Standard options include 512x512, 768x768, 1024x1024, and various widescreen and portrait ratios like 16:9, 9:16, 3:2, and 2:3. Higher resolutions are available on paid plans with upscaling options up to 4x.
How do I write effective prompts for ZSky AI?
Be descriptive and specific about what you want to see. Include details about subject, style, lighting, composition, and mood. For example, instead of "a cat," try "a fluffy orange tabby cat sitting on a windowsill, golden hour sunlight, soft bokeh background, photorealistic." You can also use negative prompts to exclude unwanted elements.
What are negative prompts and how do I use them?
Negative prompts tell the AI what you do not want in your image. For example, adding "blurry, low quality, watermark, text" as a negative prompt helps ensure cleaner output. Negative prompts are optional but can significantly improve results, especially for photorealistic work.
Can I generate images in specific art styles?
Yes. ZSky AI supports virtually any art style you can describe in your prompt — oil painting, watercolor, anime, pixel art, photorealistic, 3D render, comic book, Art Nouveau, cyberpunk, and many more. The AI engine is particularly strong at interpreting and executing style directions. Explore our style templates for inspiration.
How long does it take to generate an image?
Most images generate in 5 to 15 seconds depending on the model and resolution selected. ZSky AI runs on dedicated RTX 5090 GPUs, so generation times remain consistent regardless of how many other users are on the platform. There is no queue-based throttling.
What is the guidance scale and how does it affect results?
The guidance scale controls how closely the AI follows your prompt. Lower values (around 3-5) produce more creative, loosely interpreted results. Higher values (7-12) make the AI adhere more strictly to your description. The default value works well for most use cases, but experimenting with guidance scale can help you fine-tune outputs.
Can ZSky AI render text in images?
Yes. The AI engine is particularly strong at rendering readable text within images, which is unusual for AI image generators. This makes it excellent for creating signs, logos, posters, and other designs that include text elements. For best results, keep text short and include it clearly in your prompt.
Video Generation
Creating Videos
What video generation with audio capabilities does ZSky AI offer?
ZSky AI offers AI video generation with audio powered by the WAN 2.2 model. You can create videos from text prompts (text-to-video) or from existing images (image-to-video). Videos can be generated at various resolutions with smooth motion and coherent scenes.
What is the WAN 2.2 model?
WAN 2.2 is a state-of-the-art open-weight video generation with audio model that produces high-quality AI videos with natural motion, consistent subjects, and coherent scene transitions. ZSky AI runs WAN 2.2 on its dedicated RTX 5090 GPU cluster for optimal performance. Learn more in our WAN model explainer.
How long can AI-generated videos be?
Video length depends on the resolution and model settings. Currently, ZSky AI supports video clips up to approximately 5 seconds per generation. You can generate multiple clips and combine them for longer sequences. Video duration capabilities are actively being expanded.
What resolution are AI-generated videos?
ZSky AI supports video generation with audio at multiple resolutions including 480p, 720p, and higher depending on your plan. The RTX 5090 GPUs with 32 GB GDDR7 memory provide the computational power needed for high-resolution video generation with audio without quality compromises.
Can I convert an image to video on ZSky AI?
Yes. ZSky AI supports image-to-video generation with audio. Upload any image — including images you generated on ZSky AI — and the WAN 2.2 model will animate it into a video clip based on your text prompt describing the desired motion and camera movement.
How many credits does video generation with audio use?
Video generation uses more credits than image generation because it requires significantly more GPU computation. A single video generation with audio typically uses between 10 and 25 credits depending on resolution and duration settings. Check the generation interface for exact credit costs before generating.
