For individual use without specially negotiated Enterprise stuff I can't afford both offer contractual assurances of not using your data for training or ads and measurement and selling your data.

But these are not the same level of technical assurance you get from say, a zero data retention provider on OpenRouter.

Right now I am finding I have to tolerate substantial friction to use Hermes for personal stuff with a ZDR provider and ChatGPT and Codex for less personal stuff because the products and models are simply so much better.
