I'm curious what the model provider is using the prompt/response pairs for, in that case. They aren't offering a model for free without their name on it for no reason.
Like they dont pretrain on your chats but they do some transforms/RLHF/sentiment analysis. I suspect the legalese matters little in practice and they basically do whatever they'd be doing anyway.
its pretty clearly nit a contract with open router, and you have no agreement with the lab to not train
LLM needs to become more transparent, not less. Hence, this idea (and trend, possibly) is disgusting.
How can we even possibly verify 'Prompts and completions are retained by the provider and are not used for training...'? What if the training is done, but used internally?
Openrouter has had stealth models for a while. They have had free models for a while. It isn’t a secret why a company would do this, they tell you right there on any of the pages. Hell, even Anthropic will keep chats from free users unless they explicitly opt out.
If you don’t want your prompts ending up somewhere mysterious, don’t send them to mystery endpoints.
