Vercel AI Gateway Finds Anthropic’s 2:1 Lead
Vercel’s November 2026 Production Index, based on anonymized traffic through October, finds Anthropic was the first-choice lab for new paid teams at nearly 2:1 over OpenAI. Decision models also captured 26% of gateway requests while accounting for only 0.53% of spend.
Anthropic’s acquisition lead is significant, but the broader story is model choice fragmenting by workload, price, and team maturity.
- –Mature teams are nearly split: OpenAI reached 55% and Anthropic 54% of teams tracked since December.
- –OpenAI’s gateway spend share rose to 14.5%, while Anthropic still led at 32.2%, suggesting OpenAI is gaining high-value production workloads.
- –Decision models show how cheap specialized inference can reshape routing economics: Jev handled nearly four times Anthropic’s requests, yet Anthropic captured 64 times its spend.
- –Model loyalty is weakening, with teams rapidly switching to newer releases and often changing labs.
- –Voice adoption rose sharply, signaling that production AI stacks are expanding beyond text generation.
