How GLM‑5.1‑highspeed Achieves 7× Faster Inference to Become the World’s Fastest Flagship Model
On May 22, Zhipu launched the GLM‑5.1‑highspeed API, delivering 400 tokens per second—about 7× faster than the original model and twice as fast as Gemini 3.5 Flash—through a three‑layer optimization that rewrites the MoE inference path, introduces dynamic scheduling, and leverages TileRT’s AOT engine to cut latency while preserving full flagship capabilities.
