DeepSeek is pushing the boundaries of AI development by tackling the challenge of training models that think more like humans, focusing on reasoning and reinforcement learning. The company's latest models, DeepSeek R.1 and R.1.0, have shown impressive performance in reasoning tasks without relying on traditional pretraining methods, with competitive results even surpassing OpenAI's O 1 model. These models use reinforcement learning to refine reasoning, guided by rewards for accuracy and formatting, leading to the emergence of "thinking brackets" and self-correction during reasoning processes. To improve readability, DeepSeek introduced supervised fine-tuning and improved readability features. The team has also distilled massive models into smaller, more efficient versions, making them ideal for local deployment where speed and resource efficiency matter. With potential applications in enterprise AI, prompt engineering, privacy-focused AI, traditional ML tasks, and AI agents & tool use, DeepSeek's innovative approach to reinforcement learning is redefining the boundaries of AI development.
