Enterprise AI usage data shows open‑weight models rising and prices stabilizing
Vercel’s July 2026 AI Gateway Production Index, based on June 2026 production traffic, reports that open‑weight models now account for 29% of token volume, while price per token has flattened even as total token volume and spend both grew around 27–29%. Anthropic models still dominate spend in high‑stakes use cases, but open‑weight adoption is accelerating for cost‑sensitive workloads.
Design your first AI MVPs so that prompts, evaluation harnesses, and safety filters are model‑agnostic, allowing you to route specific workloads to lower‑cost open‑weight models as they mature and to premium providers for safety‑critical flows.
highIf your current stack hard‑codes a single model provider into application logic, you may be overpaying and unable to respond quickly if future pricing, throttling, or licensing terms change.
