DeepSeek R1 Review: Features, Performance & AI Comparison

Introduction

DeepSeek R1 has emerged as one of the most powerful AI models, gaining significant attention in the AI community. With an impressive Mixture-of-Experts (MoE) architecture and competitive performance benchmarks, it challenges major AI models like OpenAI’s GPT-4. But does it truly live up to the hype? This review explores its key features, strengths, weaknesses, and real-world applications.

What is DeepSeek R1?

DeepSeek R1 is an open-source language model developed by a Chinese AI startup. Launched in January 2025, it utilizes an advanced MoE architecture, incorporating 671 billion parameters, with only 37 billion active at any time. This innovation allows for efficient computational power usage while maintaining top-tier AI capabilities.

Key Differentiators

• Efficient Processing: Uses only 2,000 NVIDIA H800 chips compared to the 16,000 required by competitors.
• Rapid Development: Completed training in just 55 days at a cost of $5.6 million—significantly lower than competitors like GPT-4.
• Cost-Effective API Pricing: Priced at $0.55 per million input tokens and $2.19 per million output tokens, making it more affordable than many alternatives.

DeepSeek R1’s Market Position

DeepSeek AI's launch had a significant impact on the AI industry, even causing Nvidia’s stock to take a major hit. Its open-source approach makes it accessible to developers, researchers, and businesses looking for advanced AI solutions without massive investments.
