AI Generation Assist Tools — Optimize Prompts & Outputs
Specialized AI tools to refine prompts, upscale images, and restore faces. Elevate every generation with intelligent pre- and post-processing.
Specialized Assist Models
Improve your generation quality with essential auxiliary tools for prompt refinement, image upscaling, and face restoration.
Prompt Refinement & Enhancement
Automatically rewrite and expand simple prompts into detailed, model-optimized descriptions. Our prompt refiner understands what each foundation model responds to best and tailors your input for maximum output quality.
AI Image Upscaling (Super Resolution)
Increase image resolution by 2x or 4x using Real-ESRGAN. Hallucinate realistic details, sharpen edges, and enhance textures without artifacts. Perfect for turning AI-generated thumbnails into print-ready assets.
Face Restoration (CodeFormer)
Fix blurry, distorted, or damaged faces in AI-generated images and real photographs. CodeFormer reconstructs facial details with remarkable fidelity — eyes, teeth, skin texture — while preserving the original identity.

FAQ
These are specialized, smaller AI models designed to support the main generation process. They don't generate images from scratch but rather help prepare the input (prompts) or improve the output (upscaling, fixing).
It is not mandatory, but highly recommended if you want to maximize the potential of models like Stable Diffusion or FLUX. Better prompts almost always lead to better images.
Yes. While primarily used for fixing AI-generated faces, CodeFormer is also excellent at restoring old, blurry, or damaged real-world photographs.
Generally, assist tools are much lighter and faster than full generation models, so they consume significantly fewer credits. Some simple pre-processing steps may even be free depending on your plan.
Yes. With the WaveSpeed API, you can define a "workflow" in your JSON request. For example, you can request generate_image with restore_faces: true and upscale: 2x, and the system will run the assist tools in sequence automatically.
