# 开放权重模型占token量56%，Astra的Fable 5.1支出翻倍

Vercel发布AI Gateway九月生产指数：开放权重模型在网关路由的token总量中占比达到56%。同时，Astra公司将Fable 5.1的支出翻了一倍。该指数基于AI Gateway每月路由的数万亿token生产流量，反映企业实际AI使用情况。开放权重模型超过一半的token份额，说明企业在生产环境中对可自托管的模型接受度在提升。对关注模型选型和成本控制的团队来说，这是一个值得跟踪的信号。

## English Version

**Open-Weight Models Hit 56% of Token Volume, Astra Doubles Fable 5.1 Spend**

Vercel's AI Gateway Production Index for September 2026 shows open-weight models now account for 56% of token volume routed through the gateway. Meanwhile, Astra doubled its spending on Fable 5.1. The index is based on tens of trillions of tokens routed monthly between production applications and AI labs, reflecting actual enterprise AI usage. Open-weight models crossing the halfway mark suggests growing enterprise acceptance of self-hostable models in production. A signal worth tracking for teams focused on model selection and cost control.
