A2UI is an interesting project for a streaming-oriented protocol for applications with LLM integration. The basic idea is streaming JSON snippets from which the UI is then incrementally built, and the LLM controls what goes into the UI. It allows the LLM to produce more than just simple textual descriptions or basic ASCII graphics and also gives LLM queries a different look. The whole thing comes from Google and is maintained on an open github project. In bDS, I have also integrated it, and it's quite something when you can get a heatmap of the distribution of your blog posts across the months.
