DeepSeek V3 vs R1: Feature, Performance & Model Comparison Guide
DeepSeek V3 and R1 represent two distinct approaches in the open-source large language model field. V3 relies on a mixture-of-experts architecture to deliver strong multitask performance, while R1 is designed for logical reasoning and efficient problem solving.
This article compares their strengths, features, and user experiences to help you determine which model best fits your needs. If you're searching for a clear DeepSeek V3 vs R1 comparison, this guide provides detailed insights into both models.
What is DeepSeek V3?
DeepSeek V3 is a 671 billion-parameter model built on a mixture-of-experts (MoE) structure, activating 37 billion parameters per token to optimize for both task variety and processing speed (GitHub). The model is trained on 14.8 trillion high-quality tokens and extends its context window to 128K, making it well-suited for processing long documents (arXiv). Its pre-training is efficient, requiring just 2.664 million H800 GPU hours, which demonstrates effective scaling without sacrificing performance (Hugging Face).
