| Category | — | Image Generation |
| Description | Leonardo AI is a creative AI platform for generating images, textures, and assets with fine-tuned control. Popular with game developers and artists for its ability to create consistent styles, train custom models, and generate production-ready assets. | Open-source latent diffusion model for local image generation, now at SD3.5 with improved composition and text rendering. Self-hostable on consumer GPUs (8GB VRAM minimum for SD3.5 base), with an extensive ecosystem of fine-tuned models on Civitai. Stability AI underwent restructuring in 2025 after funding challenges but the open-source ecosystem remains active. |
