前几天，幻方发布的DeepSeek-V2引起了大家的热烈讨论。首先，最让人哗然的是1块钱100万token的价格，普遍比现有的各种竞品API便宜了两个数量级，以至于有人调侃“这个价格哪怕它输出乱...| spaces.ac.cn
We present DeepSeek-V2, a strong Mixture-of-Experts (MoE) language model characterized by economical training and efficient inference. It comprises 236B total parameters, of which 21B are activated for each token, and supports a context length of 128K tokens. DeepSeek-V2 adopts innovative architectures including Multi-head Latent Attention (MLA) and DeepSeekMoE. MLA guarantees efficient inference through significantly compressing the Key-Value (KV) cache into a latent vector, while DeepSeekMo...| papers.cool
事实上，除了写博客内容，在这几年里，笔者是花了相当一部分时间来做科学空间的“表面功夫”，为此还专门学了一点php、css和js。虽然不敢说精益求精，但总体来说网站的浏览体验应该比前几年要好得多。...| spaces.ac.cn
In the process of working on calm, a minimal from-scratch fast CUDA implementation of transformer-based language model inference, a critical consideration was establishing the speed of light for the inference process, and measuring the progress relative to that speed of light. In this post we’ll cover this theoretical limit and its implications.| zeux.io
