Stability AI
Stability AI is the British AI company that created Stable Diffusion — the open-source image model that democratized AI image generation. Their 2022 decision to release Stable Diffusion as open source triggered an explosion of community fine-tuning and derivative models, fundamentally changing the generative AI landscape. Despite financial turbulence in 2023–2024, Stability AI continues developing the SD 3.x series, pushing improvements in typography, compositional understanding, and anatomical accuracy.
