Stability AI

Stability AI created Stable Diffusion and helped kick off the whole open-source generative AI ecosystem, later adding Stable Video Diffusion, Stable Audio, and Stable LM. The company went through serious turmoil in 2024 — founder and CEO Emad Mostaque resigned amid financial and governance troubles, and new leadership under CEO Prem Akkaraju brought in fresh investment to stabilize the business, a reminder that even the company behind a genuinely foundational open model can go through real existential pressure.
