## What the numbers say

Take 1,000,000 requests a month at 1,200 input and 350 output tokens each. That workload costs $1,315 a month on Deepseek V3.1 NVFP4 and $3,220 on GLM 5.2 at list: a gap of $1,905, or 2.4x.

GLM 5.2 reads 256K tokens per request against 128K for Deepseek V3.1 NVFP4, 2.0x the window. That decides which one can take whole documents without splitting them.

## Choose Deepseek V3.1 NVFP4 for

- The lower list price ($0.60 in / $1.70 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
