Stability AI trains AI-backed tools that focus on image generation (although this image was created by artist Yaroslav Kushta).

If you can describe it in words, Stability AI can turn it into a picture. Stable Diffusion , a free, open-source text-to-image generator that the company helped train, changed the world’s understanding of AI’s potential when it launched in August. But Stability AI soon found itself at the center of debate—and copyright lawsuits—over how it trains those tools on data (and art) pulled from the internet. Still, the company says that within a month of launching Stable Diffusion 2.0, it powered four of the App Store’s top 10 apps. CEO Emad Mostaque, reportedly prone to making exaggerated claims about his company, says Stability AI’s “true open-source approach” creates “a path for break­throughs.”
