DeepSeek V3 is a state of the art Mixture of Experts language model designed for high performance and efficiency. It features 671 billion total parameters, with 37 billion activated per token. The model incorporates innovative components such as Multi-Head Latent Attention and the DeepSeekMoE framework, ensuring optimized inference speed and cost effective training.
How DeepSeek Works
- Multi-Head Latent Attention (MLA) This approach compresses attention keys and values, reducing memory requirements while maintaining accuracy. Only essential compressed vectors are cached during inference, significantly improving efficiency.
- DeepSeekMoE Framework The model employs a mix of shared and routed experts to process input tokens dynamically. A bias-adjusted scoring system ensures balanced expert loads, eliminating the need for auxiliary loss methods that often degrade model performance.
- DualPipe Training Algorithm Communication overhead in distributed training is minimized using DualPipe, which overlaps the computation and communication phases. This strategy significantly boosts training speed and scalability.
- FP8 Mixed Precision Training Using an FP8 data format, DeepSeek-V3 reduces memory and computational costs. Fine-grained quantization strategies ensure stable and accurate training while handling the challenges of low precision.
- Multi-Token Prediction (MTP) Unlike traditional models that predict one token at a time, DeepSeek V3 predicts multiple future tokens at each step. This improves data efficiency and allows for a better understanding of context.
DeepSeek-R1 Architecture
The DeepSeek-R1 architecture is designed to enhance AI reasoning using a structured multi-stage training process that combines reinforcement learning (RL), supervised fine-tuning (SFT), and model distillation.
