DeepSeek R1: Unlocking the Future of AI Reasoning on Exatron Workstations
Introduction
DeepSeek R1, a cutting-edge reasoning model, has emerged as a strong competitor to proprietary AI systems like OpenAI’s o1 series. Built using reinforcement learning techniques and leveraging advanced pre-training methodologies, DeepSeek R1 demonstrates state-of-the-art performance in tasks such as mathematics, coding, and logical reasoning. Its ability to execute complex thought processes autonomously makes it a prime candidate for deployment in enterprise AI applications.
Executive Summary: Why is this important
The evolution of AI began with pattern recognition, which gradually advanced into language models and later into predictive large language models (LLMs) powered by transformer-based attention mechanisms. This marked the era of GPT models—capable of predicting the probability of the next word in a sentence, generating coherent and contextually relevant text. Over time, this predictive approach expanded beyond text, finding applications in speech, vision, and other domains.
However, despite the rapid advancements and widespread adoption of predictive AI, one fundamental challenge remained unresolved: these models lacked reasoning. While they could predict the next word or action with remarkable accuracy, they did not understand why their predictions were correct or incorrect. In essence, they lacked logical thought. This gap was bridged by OpenAI’s O1, the first model to introduce reasoning and cognitive capabilities, revolutionizing the AI industry. However, this breakthrough remained proprietary, leaving open-source alternatives struggling to keep pace.
Reasoning is a game-changer for AI. It enables models to improve accuracy, solve complex problems, and even translate intelligence into the physical world. For instance, robots operating in real-world environments cannot function based on prediction alone—they require contextual understanding, memory, and reasoning to make meaningful decisions and collaborate effectively with humans.
Last week, in a surprising and disruptive move, DeepSeek, a China-based AI company, unveiled DeepSeek- R1 and DeepSeek-R1-Zero, two models that introduce reasoning capabilities and benchmark competitively against OpenAI’s O1. More significantly, DeepSeek has open-sourced these models, sparking widespread adoption among developers and AI researchers. The impact has been immediate— DeepSeek has surged to the top of the Apple and Android App Stores, rapidly gaining traction across the globe.
The Architecture of DeepSeek R1
DeepSeek R1 is built on top of DeepSeek-V3, which features a Mixture of Experts (MoE) model with 671 billion parameters, a model architecture that dynamically selects different subnetworks (experts) for each input, reducing computational costs while enhancing performance. This approach contrasts with dense models, which activate all parameters for every computation, making MoE significantly more efficient for
large-scale AI applications., a design that improves computational efficiency by activating only a subset of parameters per query. This selective activation optimizes resource usage, allowing DeepSeek R1 to maintain high performance in complex reasoning tasks by activating only 37 billion parameters per forward pass, ensuring efficiency without compromising accuracy. This allows for computational efficiency without compromising accuracy. The model’s training process includes:
Reinforcement Learning (RL): DeepSeek R1 employs RL to enhance reasoning capabilities without requiring supervised fine-tuning (SFT) as a preliminary step.
Cold-Start Training: Initial fine-tuning with a small amount of high-quality reasoning data ensures better readability and structured reasoning outputs, meaning the model can present its thought process in a logical and easily interpretable manner, improving user understanding and trust.
Distillation: To make DeepSeek R1 accessible to a broader audience, the model has been distilled into smaller versions (1.5B, 7B, 14B, 32B, 70B), making it possible to run on various hardware configurations. Distillation helps reduce computational overhead while preserving most of the model’s reasoning capabilities, ensuring that even smaller versions maintain high levels of accuracy and efficiency for AI applications.
Enhanced Model Efficiency: By employing a structured reinforcement learning approach, DeepSeek R1 minimizes computational overhead while maintaining its reasoning integrity, making it a suitable choice for large-scale deployments such as financial market predictions, real-time medical diagnostics, and autonomous decision-making in robotics.
How Reinforcement Learning (RL) Works
Unlike traditional AI models that rely on supervised learning (where human-labeled data is required for training), DeepSeek R1 leverages reinforcement learning (RL) to develop its reasoning abilities independently.
Trial and Error Learning:
• The model attempts different reasoning approaches on problems and receives feedback (rewards) based on performance.
• Over time, it adjusts its strategy to maximize rewards, improving its logic without direct human supervision.
• This mimics how humans refine problem-solving skills by learning from mistakes and improving strategies over time.
Self-Improvement Over Time:
• Instead of relying on large-scale human-labeled datasets, the AI learns dynamically by improving its reasoning skills through repeated training cycles.
• The model remembers what worked well in the past and gradually refines its thought process to become more accurate.
Cost Reduction:
• Traditional AI models require millions of labeled examples, which are expensive and time- consuming to produce.
• Reinforcement learning removes this dependency, allowing the model to self-train with minimal human intervention, making AI development more scalable and cost-efficient.
The Role of Group Relative Policy Optimization (GRPO)
To further optimize RL training and make it more efficient, DeepSeek R1 employs Group Relative Policy Optimization (GRPO), which introduces a unique approach to policy improvement:
Traditional RL Challenge:
• Most reinforcement learning methods require a “critic model”, which is a separate system that evaluates how good the AI’s decisions are.
• However, training this critic model is computationally expensive and can slow down the learning process.
How GRPO Solves This:
• GRPO eliminates the need for a separate critic model, reducing the computing power required for training.
• Instead, it compares multiple AI-generated answers for a given problem and optimizes the model by rewarding the best responses relative to the others.
• By making learning more efficient, GRPO helps cut training costs while improving the model’s ability to reason accurately.
Reward System for Smarter Learning
• Since the AI doesn’t receive direct instructions, a reward system is crucial to guide its learning process. DeepSeek R1 uses a two-part reward mechanism to shape its behavior:
• Accuracy Rewards (Getting the Right Answer)
• The AI receives a higher reward for correct answers, ensuring it prioritizes accuracy.
• In structured fields like mathematics, logic, and coding, where answers can be objectively verified, rule-based evaluation determines correctness.
• Example: In math problems, the AI’s response is checked against the actual answer. For coding problems, a compiler runs the solution against test cases.
Format Rewards (Explaining Its Thinking Clearly)
• Beyond just getting the answer right, DeepSeek R1 is trained to present its reasoning process in a structured and human-readable way.
• The AI is rewarded for:
• Breaking down problems step by step.
• Clearly explaining its logic before arriving at an answer.
• Using structured formats, such as putting reasoning in <think></think> tags before presenting the final result.
Why This Matters
• Without this system, the AI might guess answers without explanation, making its reasoning unreliable and difficult to trust.
• With accuracy rewards, it learns to provide correct answers.
• With format rewards, it learns to explain its thought process, making it more interpretable and useful for real-world applications.
• This results in a model that doesn’t just “memorize” answers but thinks through problems systematically, improving its usability in domains like science, engineering, and finance.
How DeepSeek R1 is Rewarded Without Human Intervention
DeepSeek R1 uses a rule-based reward system, where predefined, objective criteria determine whether the model’s responses are good or bad. This allows the AI to self-train without needing constant human feedback.
There are two primary reward mechanisms that guide its learning:
Accuracy Rewards (Objective Scoring System)
• Instead of relying on humans to grade answers, predefined rules automatically assign scores based on correctness.
• This is ideal for subjects with clear right or wrong answers, such as:
• Math problems: The AI’s response is compared against the correct answer.
• Coding tasks: The AI’s code is run through a compiler and tested against known test cases.
• Logic puzzles: Answers can be verified with strict logical conditions.

• If the AI gets the answer right, it receives a positive reward. If it’s incorrect, it gets a negative reward, forcing it to improve over time.
Example:
• Ǫuestion: What is 5 + 3?
• AI Answer: 7 → Negative reward
• AI Answer: 8 → Positive reward
Format Rewards (Encouraging Better Explanations)
• Beyond just getting the right answer, DeepSeek R1 is also rewarded for explaining its reasoning in a structured way.
• The AI must show its thinking process by organizing responses properly.
• A format-checking system evaluates whether the AI follows correct reasoning steps before arriving at an answer.
Example:
• If the AI only gives an answer without explanation, it receives a lower reward.
• If the AI breaks down the problem step-by-step, it receives a higher reward.
Structured format required:
AI should place its reasoning inside <think></think> tags before giving an answer. Correct Format:
<think> The sum of 5 + 3 is calculated as follows: 5 plus 3 equals 8. </think>
<answer> 8 </answer> Receives higher reward Incorrect Format:
<answer> 8 </answer>
Lower reward, because reasoning is missing!
Why This Works Without Human Input
The AI is not graded by humans but by automated rules that check:
• Is the answer correct? (Compared to expected output)
• Is the reasoning structured properly? (Using predefined format rules)
• Predefined evaluation metrics make sure rewards are fair and don’t require human review for every answer.
What About More Complex Questions?
For more abstract or open-ended problems, DeepSeek R1 can still learn from comparison-based rewards using Group Relative Policy Optimization (GRPO):
• Instead of assigning a score manually, GRPO compares multiple AI-generated answers and rewards the best responses relative to others.
• Over time, the AI learns which patterns lead to better answers without needing direct human input.
Hardware Used to Train DeepSeek R1
Although this is mostly speculation, we have some information on the hardware used to train Deepseek R1.
