GLM 5.2 Fast via Wafer is now available on AI Gateway .

Based on our own benchmarking across small-context, large-context, and tool-call scenarios, Wafer delivers a 2x higher throughput than other providers serving GLM-5.2 on serverless, leading on decode and end-to-end speed for sustained generation in the small- and large-context cases.

In our testing, GLM 5.2 Fast on Wafer measured:

Small context: 170+ tok/s

Large context: 200+ tok/s

To use GLM 5.2 Fast, set model to zai/glm-5.2-fast in the AI SDK :

import { streamText } from 'ai' ;

const result = streamText ( {

model : 'zai/glm-5.2-fast' ,

prompt : 'Add error recovery to the data ingestion pipeline.' ,

} ) ;

AI Gateway provides a unified API for calling models, tracking usage and cost, and configuring retries, failover, and performance optimizations for higher-than-provider uptime.…
