UnverifiedThe three 4-bit quantization schemes—RTN, GPTQ, and AWQ—have similar compression ratios but progressively increasing precision retention capabilities.72% similarUnverifiedSome ONNX exports labeled q4 are larger than the q4f16 versions because the embedding table retains 32-bit precision; for example, SmolLM2-360M's q4 is 390MB and q4f16 is 275MB, and the two produce identical outputs.66% similarUnverifiedMost consumer-grade TTS engines output 16-bit PCM, and 16-bit is already enough to cover normal listening environments; 24-bit provides extra headroom only during post-processing such as multitrack mixing, EQ or compression.65% similarUnverifiedMiniCPM和Qwen-0.5B等1B以下轻量模型配合INT4量化可以在手机芯片上运行65% similarUnverifiedWhen VRAM is less than 16GB, it is recommended to consider Q2 or switch to a smaller parameter model; 1-bit is not recommended.65% similar
