Models are often trained with FP32 or mixed precision, and are usually converted to FP16 when releasing inference versions to halve the size.

UnverifiedLow-precision training and inference (FP16, FP8, FP4) are key to the current ability of large models to scale to trillion parameters.79% similarUnverifiedFSDP shards model parameters, gradients, and optimizer states across multiple GPUs, and is the mainstream solution for training models with hundreds of billions of parameters72% similarUnverifiedTechnical approaches to mitigating the inference wall include model quantization (reducing FP16 to INT8 or INT4), speculative decoding (using a small model to predict large model outputs to accelerate generation), and KV Cache optimization.70% similarUnverifiedGPTQ and AWQ are the mainstream directions for post-training quantization, capable of compressing models to 4-bit precision with almost no loss in perplexity.70% similarVerifiedThe essence of model quantization is to map a model's floating-point weights and activations (typically FP32) to low-bit-width representations (such as INT8 or INT4), thereby reducing memory usage, improving inference speed, and lowering power consumption.70% similar
