Price from Venice: the cheapest offer that is serving, at standard delivery and at a declared precision that is not 4-bit (fp8), at its standard rate. The maker’s own precision is not known.
Cheaper right now: $0.925/M at DeepInfra — 4-bit It does not pass the like-for-like test, so it never sets a rank.
