AI Models
Pixel Nova uses machine learning models hosted on Hugging Face for AI-powered pixel art generation. The following models are currently in use. Additional models may be integrated in the future.
Retro Pixel Flux LoRA
Used for text-to-image pixel art generation via the Hugging Face Inference API. This model is a LoRA fine-tune that produces retro-style pixel art sprites from text prompts.
Model: prithivMLmods/Retro-Pixel-Flux-LoRA
Platform: Hugging Face
Integration: Hugging Face Inference API (server-side)
SpriteFusion Pixel Snapper
Pixel Nova uses the SpriteFusion Pixel Snapper for post-processing AI-generated pixel art. The tool snaps pixels to a clean, consistent grid and quantizes colors to a strict palette, correcting the inconsistent pixel sizes and grid drift that AI image models typically produce. We compile the Rust source to WebAssembly and run it server-side in Node.js.
