## What the numbers say

Take 1,000,000 requests a month at 1,200 input and 350 output tokens each. That workload costs $1,240 a month on GLM 4.7 FP8 and $3,220 on GLM 5.2 at list: a gap of $1,980, or 2.6x.

GLM 5.2 reads 256K tokens per request against 198K for GLM 4.7 FP8, 1.3x the window. That decides which one can take whole documents without splitting them.

## Choose GLM 4.7 FP8 for

- The lower list price ($0.45 in / $2 out per M tokens)
- Fine-tuning under a permissive license (MIT)

## Choose GLM 5.2 for

- Agents on open weights
- Code and structured outputs
- Fine-tuning toward an owned model
