The llama models are more open source than gpt-3.5-turbo. They aren't "free software" in the full definition, but they are available to be fine-tuned, modified, run offline, and generally tinkered with. For AI, "open source" is less about the license and what it allows you to do legally, and more about what the technology allows you to build practically. If/when Meta gets litigious, this might change in a hurry. Right now, there are bigger risks to AI startups (not Google) than worrying about how they'll choose to enforce the llama license.
