Architecture: A Groundbreaking Design for Reasoning

DeepSeek-R1: Mixture of Experts (MoE) at Its Core

DeepSeek-R1 employs an advanced Mixture of Experts (MoE) architecture, boasting an astounding 671 billion parameters. However, its design ensures that only 37 billion parameters are activated during any single forward pass. This selective activation, guided by a sophisticated routing system, optimizes computational efficiency without sacrificing performance. By dynamically engaging specific parameter subsets based on the reasoning demands of each query, DeepSeek-R1 excels in:

• Handling long-context reasoning, traversing thousands of tokens coherently.
• Maintaining computational efficiency, achieving speeds surpassing traditional dense models.

The MoE design employs techniques like Sparse Gate Activation, where routing decisions are made by a gating network that directs input to the most relevant experts. These gating networks are trained using regularization methods like Load Balancing Loss, ensuring that no single expert becomes a bottleneck. This balance enhances both scalability and reliability, making DeepSeek-R1 adept at processing diverse inputs with consistent quality.

DeepSeek-R1-Zero: Reinforcement Learning without Supervised Fine-Tuning

In a bold departure from conventional training paradigms, DeepSeek-R1-Zero was developed purely via reinforcement learning (RL), skipping supervised fine-tuning. This model’s architecture evolves autonomously through a process called self-evolution, allowing it to develop:

• Long chains of thought (CoT), enabling deep reasoning.
• Reflection and reevaluation capabilities, often associated with human-like problem-solving.
• Intriguing emergent behaviors, such as “aha moments,” where the model discovers new reasoning pathways.

R1-Zero employs Group Relative Policy Optimization (GRPO), which simplifies RL by eliminating the need for critic networks. Instead, the model directly optimizes reward signals associated with task performance, enhancing efficiency and reducing computational overhead. Its training incorporates Exploration-Driven Sampling, which diversifies learning trajectories and helps the model excel in novel scenarios.

"Aha Moments" of DeepSeek-R1-Zero

An "Aha Moment" refers to instances where DeepSeek-R1-Zero demonstrates emergent reasoning capabilities beyond its training scope. For example:

• Mathematical Insight: When solving a complex geometry problem, R1-Zero identified an unorthodox but mathematically valid solution path, showcasing lateral thinking.
• Programming Challenge: In a competitive coding scenario, R1-Zero dynamically optimized an algorithm, reducing its time complexity without explicit instructions.

These moments highlight R1-Zero’s ability to synthesize knowledge across domains, reflecting a depth of reasoning comparable to human ingenuity. While innovative, DeepSeek-R1-Zero faced challenges in readability and language consistency, addressed in the subsequent development of DeepSeek-R1.
