You aren’t providing communications content privacy, you’re providing a meta data proxy which is not remotely the same.
If you submit personal information in your Prompts, it may be reproduced in the Outputs, but no one can tell whether it was you personally submitting the Prompts or someone else.
What else should they call it? I suppose "anonymous" could work (i.e. they only know about you what you tell them).
Either use one of the many open models that beat GPT-3.5 and you have a real, and better!, product.
I literally have no idea what the point of this is, or why not make the actual step of rolling out a real private LLM. It’s literally inferior to what Mixtral provides right now, under Apache license.
