)How Flow AI makes k3 cheaper
Flow AI runs an open market for inference: it clears each request at the lowest price across every provider hosting k3 — direct APIs, inference providers, flat-rate subscriptions, and self-hosted nodes — and bills you the true (prompt-cache-aware) cost plus a flat 2.5%. The published rate is always the ceiling. See the docs or all models.
