The open source war is over, however much some want to continue soldiering on. Recently Meta (Facebook) released Llama 2, a powerful large language model (LLM) with more than 70 billion parameters. In the past, Meta had restricted use of its LLMs to research purposes, but with Llama 2, Meta opened it up; the only restriction is that it can’t be used for commercial purposes. Only a handful of companies have the computational horsepower to deploy it at scale (Google, Amazon, and very, very few others).
This means, of course, it’s not “open source” according to the Open Source Definition (OSD), despite Meta advertising it as such. This has a few open source advocates crying, Rambo style, “They drew first blood!” and “Nothing is over! Nothing! You just don’t turn it off!”, insistent that Meta stop calling Llama 2 “open source.”
