Why is Meta: Muse Spark Open cheaper on UberLLM?
UberLLM is a market: sellers offer Meta: Muse Spark Open capacity below its list price, and each request goes to a seller that can serve it. A request costs what its seller charged, UberLLM adds no fee to it, and every request is listed with its cost in Activity.
Can a request cost more than this price?
Yes, when the lower-priced sellers are busy. Send provider.max_price with the most you will pay per million tokens: the request only goes to sellers at or under it and is never billed above it.
