GLM-5.3-Flash retains 93% accuracy when quantized to 4-bit
amaarora · x · 2026-08-28
GLM-5.3-Flash (ox-alpha) can be quantized to 4-bit while retaining 93% accuracy. The 4-bit model performs similarly to a local Claude 4.7 Opus. It runs perfectly on a 256GB Mac or two DGX Sparks, with 5-bit potentially viable. UnslothAI also released a guide for running a 3-bit version via GGUF on 128GB RAM.
