The small, fast Z.ai model is GLM 4.5 Air — the efficient tier at 54 tokens/sec and $0.125 per million input tokens. It trades a few points of raw intelligence for speed and cost, the right call for high-volume, latency-sensitive work. GLM 4.7 Flash (47 t/s) is next.
Compact, efficient models — the small/mini/flash/haiku tier — ranked by output speed. These trade a little raw intelligence for low cost and high throughput, which is the right tradeoff for chat, classification, extraction and other high-volume work.
