alt Hacker NewsStealth Model, is this a CTF?
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?
This isn’t new.
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.
