I think any new model not demonstrably maybe 20-30% over Deepseek v4 capabilities priced over the price per token of Deepseek is almost automatically deprecated as low use model (maybe for Planning).
- twice as expensive on the output (1.52 vs 0.87)
- six times as expensive on the input (0.33 vs 0.05)

If anything, DS4 has 1 million context window, while GLM 5.1 has 200K.
There are also benchmarks comparing the two: https://artificialanalysis.ai/models/comparisons/deepseek-v4...
