Yes they do, it's quite the popular topic atm.
RouteLLM (OSS - frugon's savings bands are based on their research), OpenRouter's auto mode; I actually commented on a /show post not long ago: Wayfinder Router (neat project) - https://news.ycombinator.com/item?id=48704373 and more.
My stance on the router point is a config-led (deterministic) one, even if the eventual industry consensus is a hybrid of dynamic (AI-led) + deterministic. Both sides still require evals/evidence for policy creation, which is what frugon provides.
