Test Shows Progressive Capability Degradation in Quantized GLM 5.2

Sentdex · x · 2026-07-03

Sentdex detailed a comparison of various model quantizations on Terminal Bench v2.1. GLM 5.2 shows a noticeable performance drop moving from native precision to FP8, and degrades further from FP8 to IQ4NL. Dropping from 4-bit to 2-bit also incurs losses, though the trade-off might be worth it. This直观 demonstrates how model capabilities degrade step-by-step with quantization, and he plans to test 1-bit next.
