StudioNanbeige4.3-33B GGUF quants released, with AD files beating llama.cpp presets at same size
Original title: Nanbeige4.3-33B Quantised GGUF
AtomicChat released GGUF quants of Nanbeige4.3-33B, a 33B dense agent and reasoning model with Llama architecture, 512K context, thinking on by default, under Apache-2.0. Built from the BF16 weights on release day, the Atomic Dynamic (AD) files use a custom importance matrix and span 13.7 GB to 30.1 GB, each measured against the BF16 original with KL divergence and top-1 metrics. The author notes the model is unusually sensitive to quantization: AD-IQ4_XS (20.3 GB) has about a third less KL divergence than llama.cpp's Q4_K_M (20.1 GB), and sub-4-bit quants are recommended only when nothing larger fits.
The author provides KL divergence and top-1 numbers for each quant on a unified benchmark, helping readers pick a GGUF file by disk size.
