For instance, LLaMA has been successfully ported to C/C++ ([see github link](https://github.com/ggerganov/llama.cpp)) in Spring 2023, and with some modifications to memory management can allegedly run on a Mac with an output speed in the order of seconds per token. This is not enough for a fluent conversation, but will work for processing and summarizing batches of documents, for example. And this is just one example, the work is surely going on!
