Architecture & Engineering Overview

Underlying Neural Architecture

Mixture-of-Experts (MoE) with Multi-head Latent Attention (MLA) and DeepSeekMoE sparsity

Editorial Analysis

DeepSeek-R1 introduces autonomous reasoning behaviors through pure reinforcement learning (DeepSeek-R1-Zero) followed by multi-stage refinement. It achieves competitive mathematical, coding, and logical reasoning benchmarks comparable to proprietary closed-source reasoning systems while providing full model weights under an MIT license.
