The way around that is to take the choice away from the individual. We expose three model aliases instead of model names, each mapped to the cheapest model that clears a benchmark threshold, and the cheapest one is the default. Moving up a tier is an explicit step you take when the default actually falls short, not a bet you make up front. We re-check the mapping every few days, since prices and rankings move that fast, and nobody has to change their setup when a mapping changes.
