Most LLM popular libraries are inactive, but a handful are very active. That's a product of it being a hype/popular/new field, where new projects got attention from being new, they didn't need to be ongoing to get attention. (This is fine - it serves as a way to reward people for exploring early on in a new field, which is helpful for new ecosystems) People saw that an easy way to get "github status" was to create LLM projects. Some of the LLM projects were created to be cool tools that became popular, and the devs don't have as much interest in continuing them. This is a natural thing to be expected in new and popular fields. There are still many LLM libraries that are very active. It's kinda the same as asking - why are most blogs dead projects now? The author had initial excitement, created it, shared it, the excitement/development didn't continue, but also we still have a ton of great blogs that exist on the web from the authors that did continue.
