Wafer-backed GLM 5.2 Fast delivers 2x higher throughput than competing serverless providers, with 170+ tok/s on small context and 200+ tok/s on large context.
Summary
Decode speed directly affects streaming latency in production; 2x throughput means faster token generation for sustained workloads without provider switching. AI Gateway unifies billing, retry logic, and usage tracking across models.

Implementation verdict
Drop-in replacement via model ID `zai/glm-5.2-fast` in Vercel AI SDK. Requires AI Gateway account; zero platform fee on inference. Worth testing now if you run streaming text generation or have context-heavy workloads.
