The first major projects were OpenAI's DALL-E, then DALL-E 2 a year later. DALL-E 2 was much much better. After that a few new projects have been released in rapid succession including the open source stable diffusion.

Here are some of the projects on GitHub: https://github.com/topics/text-to-image
