What is DeepSeek R1?

DeepSeek R1 is a large language model (LLM) prioritizing reasoning within generative AI systems. Advanced reinforcement learning (RL) techniques power its capabilities.

• It significantly improves LLM reasoning, minimizing reliance on supervised fine-tuning (SFT).
• DeepSeek R1 tackles a core AI challenge: enhancing reasoning without extensive SFT.

Innovative training methods enable the model to handle complex tasks in mathematics, coding, and logic.

DeepSeek-R1 Training

1. Reinforcement Learning

• DeepSeek-R1-Zero uses only reinforcement learning (RL), foregoing SFT. This approach encourages the model to independently develop advanced reasoning skills, including self-verification, reflection, and Chain-of-Thought (CoT) reasoning.

Reward System

• Rewards are based on task-specific benchmark accuracy.
• Secondary rewards incentivize structured, clear, and coherent reasoning outputs.

Rejection Sampling

• During RL, multiple reasoning paths are generated, with the best-performing ones guiding further training.

2. Cold-Start Initialization with Human-Annotated Data

• Human-annotated examples of extensive CoT reasoning initialize DeepSeek-R1 training. This ensures readability and alignment with user expectations.
• This step bridges the gap between pure RL (which can produce fragmented or ambiguous outputs) and high-quality reasoning.

3. Multi-Stage Training Pipeline

• Stage 1: Cold-Start Data Pretraining: A curated dataset of human annotations primes the model with fundamental reasoning structures.
• Stage 2: Reinforcement Learning: The model tackles RL tasks, earning rewards for accuracy, coherence, and alignment.
• Stage 3: Fine-Tuning with Rejection Sampling: The system fine-tunes RL outputs and reinforces optimal reasoning patterns.

4. Distillation

• Larger models are distilled into smaller versions, preserving reasoning performance while significantly reducing computational costs.
• Distilled models inherit the capabilities of larger counterparts, like DeepSeek-R1, without substantial performance loss.

DeepSeek R1 Models

DeepSeek R1 includes two core and six distilled models.

Core Models

DeepSeek-R1-Zero: Trained solely via RL on a base model, without SFT. It exhibits advanced reasoning behaviors like self-verification and reflection, achieving strong results on benchmarks such as AIME 2024 and Codeforces. Challenges include readability and language mixing due to the lack of cold-start data and structured fine-tuning.

DeepSeek-R1: Builds on DeepSeek-R1-Zero by incorporating cold-start data (human-annotated long CoT examples) for improved initialization. It employs multi-stage training, including reasoning-oriented RL and rejection sampling for better human alignment.

It directly competes with OpenAI's o1-1217, achieving:

• AIME 2024: Pass@1 score of 79.8%, slightly exceeding o1-1217.
• MATH-500: Pass@1 score of 97.3%, comparable to o1-1217.

It excels in knowledge-intensive and STEM tasks, and coding challenges.

Distilled Models: DeepSeek-AI also released distilled versions of the R1 model, ensuring smaller, computationally efficient models retain the reasoning capabilities of their larger counterparts. These include Qwen and Llama series models. These smaller models outperform open-source competitors like QwQ-32B-Preview while effectively competing with proprietary models like OpenAI's o1-mini.

DeepSeek R1 Key Features

DeepSeek-R1 models rival leading LLMs. Benchmarks like AIME 2024, MATH-500, and Codeforces show competitive or superior performance compared to OpenAI's o1-1217 and Anthropic's Claude Sonnet 3. Its open-source nature offers a cost-effective alternative to proprietary models.

Accessing R1

API Access: Access the API at https://www.php.cn/link/23264092bdaf8349c3cec606151be6bd. With low input costs, DeepSeek-R1 is significantly more affordable than many proprietary models.

Applications

• STEM Education: Its strong performance in math benchmarks makes it ideal for assisting educators and students.
• Coding and Software Development: High performance on platforms like Codeforces and LiveCodeBench makes it beneficial for developers.
• General Knowledge Tasks: Its success on benchmarks like GPQA Diamond positions it as a powerful tool for fact-based reasoning.

Conclusion

DeepSeek-AI's open-sourcing of DeepSeek-R1, including distilled versions, democratizes access to high-quality reasoning capabilities. This fosters collaboration and innovation. DeepSeek-R1 represents significant progress, combining open-source flexibility with state-of-the-art performance.
