UnverifiedThe K-Quant quantization method applies different quantization precision to different layers of the model, retaining higher precision for attention layers and using more aggressive compression for feed-forward layers, achieving better generation quality at the same bit width.74% similarUnverified命名中的K_M后缀表示采用分组量化策略，在相同比特数下通常保留更好的模型精度71% similarUnverifiedk-quant has become the de facto standard in the GGUF format and is widely adopted by mainstream local inference frameworks such as llama.cpp, ollama, and LM Studio.67% similarUnverified前向KL散度D(p||q)倾向于让q覆盖p的所有可能性（mode-covering），是变分推断和监督学习中最常用的形式67% similarUnverified反向KL散度D(q||p)倾向于让q集中在p的单个峰值上（mode-seeking），常用于生成模型训练65% similar
