I'm too concerned with data exfiltration to use many AI services unless their terms of service state they will not use your data for training or anything else. Zero retention is what I'm looking for. I care because I frequently work on proprietary code that I do not personally own (as most employed software devs do). So if I am using an AI service with proprietary code, I want assurances that there is no retention and no training happening. From my American perspective Chinese companies don't have the best track record of not training on proprietary information. I guess LLMs in general are trained on a lot of proprietary information. I just don't want to be responsible for unintentionally exfiltrating my employer's proprietary code.
