Stable Diffusion

Open-source image generation model (v3.5) with massive community ecosystem and local deployment

Stable Diffusion is the leading open-source image generation model from Stability AI. Version 3.5 uses an 8B parameter MMDiT architecture with improved text rendering and prompt adherence. Optimised for NVIDIA TensorRT and FP8 for faster generation and lower VRAM requirements. While SDXL retains the richest community model library for fine-tunes, 3.5 is the recommended version for new projects. Stability AI has also launched Stable Virtual Camera (2D to 3D video) and Stable Video 4D 2.0. SOC 2 Type II compliant.
