What is DeepSeek-R1?
DeepSeek-R1 is an advanced AI model designed for tasks requiring complex reasoning, mathematical problem-solving, and programming assistance. Built on a massive architecture with a Mixture-of-Experts (MoE) approach, it achieves exceptional efficiency by activating only a subset of its parameters per token. This allows it to deliver high performance without incurring the computational costs typical of similarly sized models.
Key Features:
- Large-scale RL in post-training: Reinforcement learning techniques are applied during the post-training phase to refine the model’s ability to reason and solve problems.
- Minimal labeled data required: The model achieves significant performance boosts even with limited supervised fine-tuning.
- Open-source under MIT license: Developers can freely distill, modify, and commercialize the model without restrictions.
- Performance on par with OpenAI-o1: DeepSeek-R1 matches or exceeds OpenAI's proprietary models in tasks like math, coding, and logical reasoning.
Benchmark Performance of Deepseek-R1
DeepSeek-R1 has been rigorously tested across various benchmarks to demonstrate its capabilities. Its results show that it is not only competitive but often superior to OpenAI's o1 model in key areas.
Benchmark Comparison
Highlights:
- Mathematical Reasoning: With a score of 91.6% on the MATH benchmark, DeepSeek-R1 excels in solving complex mathematical problems.
- Coding Challenges: It achieves a higher Codeforces rating than OpenAI o1, making it ideal for programming-related tasks.
- Logical Problem-Solving: The model demonstrates an ability to break down problems into smaller steps using chain-of-thought reasoning.
These benchmarks highlight DeepSeek-R1’s ability to handle diverse tasks with precision and efficiency.
Technical Architecture
DeepSeek-R1's architecture is a marvel of engineering designed to balance performance and efficiency. Here are the technical details:
Model Specifications:
- Total Parameters: 671 billion
- Active Parameters per Token: 37 billion
- Context Length: Up to 128K tokens
- Training Data: Trained on 14.8 trillion tokens
- Training Compute Cost: 2.664 million H800 GPU hours
The Mixture-of-Experts (MoE) architecture allows the model to activate only a subset of its parameters for each token processed. This ensures that computational resources are used optimally without compromising accuracy or reasoning depth.
Training Methodology:
DeepSeek-R1 employs large-scale reinforcement learning during post-training to refine its reasoning capabilities. Unlike traditional supervised learning methods that require extensive labeled data, this approach enables the model to generalize better with minimal fine-tuning.
Pricing Structure of DeepSeek-R1
One of the standout features of DeepSeek-R1 is its transparent and competitive pricing model. The API offers cost-effective rates while incorporating a caching mechanism that significantly reduces expenses for repetitive queries.
Standard Pricing:
- Input Tokens (Cache Miss): $0.55 per million tokens
- Input Tokens (Cache Hit): $0.14 per million tokens
- Output Tokens: $2.19 per million tokens
Context Caching:
DeepSeek-R1 uses an intelligent caching system that stores frequently used prompts and responses for several hours or days. This caching mechanism provides:
- Up to 90% cost savings for repeated queries.
- Automatic cache management with no additional fees.
- Reduced latency for cached responses.
For businesses handling large volumes of similar queries, this caching feature can lead to substantial cost reductions.

"stream": False
}
response = requests.post(f"{BASE_URL}/chat/completions", json=data, headers=headers)
return response.json()
result = query_deepseek("Solve this math problem: What is the integral of x^2?")
print(result)
Using cURL:
