DeepSeek is a Chinese AI company started by Liang Wenfeng in 2023 and located in Hangzhou. The organization is recognized for its innovative AI solutions and concentrates on the development of open-source large language models (LLMs). The R1 model, an open-source reasoning AI model with 671 billion parameters, was released by DeepSeek in January 2025. This model was created at a cost of $5.6 million using 2,048 Nvidia H800 GPUs, presenting a resource-efficient approach that is in direct opposition to the higher budgets of competitors like ChatGPT. The DeepSeek-R1-based chatbot app became the most downloaded free app on the U.S. iOS App Store after its release, surpassing ChatGPT.
That DeepSeek has become so successful so quickly is due to several reasons. A global community of developers who contribute to and build upon the company's models has been grown by its commitment to open-source development. Additionally, DeepSeek's emphasis on cost-effective AI solutions has increased the accessibility of advanced AI to a broader target audience. The R1 model's reputation as a premier AI provider has been further solidified by its exceptional performance in tasks such as mathematics, coding, and natural language reasoning.
DeepSeek's R1 Model: Architecture
Architectural Design
The DeepSeek R1 model is an open-source, high-performance large language model that contains 671 billion parameters. It follows a transformer-based architecture, which is comparable to GPT models. However, it includes optimizations that enhance its efficacy and reasoning capabilities.
The model is capable of managing intricate natural language, mathematics, and programming tasks due to its integration of multiple attention layers, feed-forward networks, and normalization layers. The network topology is appropriate for generative AI applications, such as chatbots, code generation, and multimodal reasoning, due to its decoder-only architecture.
R1 makes sure that calculations are carried out effectively without using an excessive amount of resources by optimizing Floating-Point Operations per Second (FLOPs) for inference. Its open-source nature makes it possible for developers and researchers to analyze and enhance its structure, in contrast to many proprietary models.
Training Methodologies
During training, the R1 model used a lot of computer resources. When training its models, DeepSeek made use of a cluster of 2,048 GPUs from Nvidia. This cost-efficient setup provided the necessary processing power, in comparison with OpenAI and Google that rely on massive, expensive infrastructures. Competitive performance was attained at a fraction of the cost by DeepSeek through the optimization of hardware usage. High-quality datasets were curated and preprocessed over several months during the training procedure.
The dataset contained multimodal tasks, mathematical reasoning, coding challenges, and natural language processing (NLP). DeepSeek implemented data filtering strategies to guarantee quality control, removing irrelevant or poor data before training. Additionally, advanced tokenization techniques were implemented to enhance the efficacy of text processing.
Distributed computation strategies were implemented in the training pipeline to manage huge amounts of data while simultaneously ensuring synchronization among GPUs. The memory requirements were reduced without sacrificing accuracy through the implementation of mixed-precision training (FP16 and BF16).
Optimization Techniques
DeepSeek R1 was designed to achieve an optimal balance between cost efficiency, accuracy, and speed by integrating a variety of contemporary optimization techniques. The model uses gradient checkpointing to reduce memory usage by selectively storing only necessary gradients during training, and sparse attention mechanisms to reduce unnecessary computations for large sequences. Furthermore, it reduces redundancy by using flexible parameter sharing and adaptive learning rates through AdamW and LAMB optimizers to enable faster convergence. R1 adapts to new tasks without retraining the whole model by using Low-Rank Adaptation (LoRA) inside the larger PEFT architecture. This combination of strategies allows R1 to provide competitive performance at a fraction of the cost of models such as Gemini and GPT-4, thereby increasing the accessibility of high-performance AI for businesses and researchers.
Advanced Data Curation and Reinforcement Learning
DeepSeek‐R1 is unique not only because it is cost-effective, but also because it uses a new way of collecting data and doing deep thinking that makes it different from other models. Its distinctive features are broken out technically here:
Curated Data for Deep Reasoning:
The training process of DeepSeek‑R1 starts with the creation of a top-notch "cold‑start" dataset. Using multiple approaches, researchers gathered thousands of chain-of-thought (CoT) examples:
Few-shot prompting: Starting with specific CoT cases to get the first results.
Post-processing of RL Outputs: The process of refining outputs from its predecessor (R1-Zero) through human review to ensure clarity and appropriate formatting.
Iterative Refinement: The process of producing a diverse and robust training corpus involves repeating the data curation cycle, which involves deduplication, filtering out low-quality or biased samples, and remixing content.
These carefully chosen datasets ensure that the model develops precise, logical thought processes that increase accuracy on challenging tasks.
Reinforcement Learning–Driven Reasoning:
DeepSeek‑R1 improves its reasoning capabilities by using a multi-stage reinforcement learning (RL) process that minimizes its dependence on supervised data:
R1-Zero Stage: The first model, which was trained only using reinforcement learning (RL) using Group Relative Policy Optimization (GRPO), shows emergent behaviors such as self-verification in which the model reconsiders and improves its first stages of reasoning.
Cold-Start Fine-Tuning: The base model (DeepSeek‑V3‑Base) is initially fine-tuned on the selected CoT dataset to enhance readability and enforce a structured output (using designated tokens such as <think> and <summary>).
Iterative RL with Supervised Fine-Tuning: Rejection sampling eliminates inconsistent results after reasoning tasks have reached convergence. Next, the model is subjected to further RL, which includes rule-based rewards for accuracy (e.g., verifying a framed final answer in mathematics) and a language consistency reward to prevent language mixing. This RL framework not only simplifies the training process but also supports deep, self-reflective thinking, which allows R1 to provide multi-step logical explanations similar to OpenAI's o1 model, but at a fraction of the cost.
Self‑Reflection and Adaptive Reasoning
DeepSeek‑R1 shows an advanced chain-of-thought process that is similar to human reasoning through its RL infrastructure.
The structure:
Allocates Extended "Thinking" Time: It dynamically changes the quantity of created reasoning tokens dependent on problem difficulty.
Self-corrects and verifies: It shows "aha moments" that increase general performance by observing mistakes in their logical stages and changing their responses.
Uses Mixture-of- Experts (MoE) architecture: Only a subset of parameters—37 billion out of 671 billion—is initiated each token, which lets specialized expert modules effectively handle domain-specific reasoning. These systems provide clear thinking procedures and help R1 to keep competitive on benchmarks such as AIME and MATH.
DeepSeek‑R1 achieves a special balance between cost, clarity, and reasoning depth by combining advanced data curation techniques with a customized reinforcement learning approach.
But wait, what is “aha moment”?
In DeepSeek, "aha moments" are occurrences during training, particularly in the reinforcement learning phase, when the model unexpectedly re-evaluates its reasoning process and adjusts its approach. The model is prompted to allocate additional "thinking" time or modify its chain of thought to arrive at a more accurate answer when these instances signify that it has identified a flaw or a more optimal path to solving a problem. There is no clear programming for this behavior to happen; it just happens as the model learns from the input it gets, showing a higher level of self-reflection and adaptive problem-solving.
