I would potentially be willing to pay a premium price for access to Fable, but I'd only consider doing so under one specific condition: that I receive some form of token rebate or credit every single time it acknowledges having messed up or given a flawed response.

The reasoning is fairly simple. If I'm paying a higher price specifically for a "premium" model, I'd expect that premium to come with some form of accountability, not just marginally better output. Right now, the cost of errors mostly falls on the user. You lose time, you burn tokens, and you have to re-prompt or fact-check things yourself, all while paying the same price regardless of how accurate the response turned out to be. A rebate system would at least tie the price partly to reliability rather than access alone.

I recognize there are practical complications. Companies would need a consistent way to define what counts as an admitted mistake, and there's an incentive problem where models might be tuned to avoid admitting fault if it costs the company money. Still, I think the underlying idea, that accuracy should factor into pricing somehow, is worth discussing.
