Open-Weight AI Models
Open weights buy you three things a closed API cannot: the option to self-host, freedom from per-token pricing at scale, and no risk of the model being deprecated out from under you. The listed prices are what hosted providers charge to run these for you; the real economics show up only when you run them yourself. Good fit for high-volume, latency-sensitive, or data-residency-constrained workloads.
