Okay, but this is rather low-level. Most users aren’t going to care about “running an LLM.” They want to ask an AI chatbot questions or get code autocompletion or something like that. What applications are there that need a local LLM and who is using them? What do they do with them?
Personally, I’m reasonably happy with GPT4 and Github Copilot, and I’ve sometimes used Midjourney, though I cancelled my subscription since I’m not currently generating any images. Are there important apps that I’m missing?
If you're happy with the commercial offerings there isn't a very compelling reason to use local models. The local ones are not "better" in general. But sometimes people have reasons to use local models, eg. privacy, customization, control, etc.
I personally use it mostly to keep tabs on the latest models released on huggingface. There has been a lot of interesting developments since last year, and models have become more and more powerful.
