hadadrjt/ai · How does Hugging Face offer so many AI models for free despite the high costs of AI development?

I'm constantly impressed by the vast collection of powerful AI models available on Hugging Face (e.g., large language models, image generation models, etc.). Given the significant computational resources and expertise required to train and develop these models, I'm curious to understand how Hugging Face is able to make so many of them accessible for free use to the community. And for example running this AI (which contains 20 other powerful model), does it costs for you something to create this space? Or it's Hugging Face give power for running this? Thank you a lot)
