Model Overview
Capabilities, design details, and architectural traits
DeepSeek R1 0528 - Reinforcement Learning-Updated Reasoning Model
DeepSeek R1-0528 is a point release of DeepSeek R1, representing a continuation of DeepSeek's reinforcement learning scaling work on top of the DeepSeek V3 base architecture. It is a dedicated reasoning model trained to produce extended chain-of-thought outputs for complex problem-solving.
Architecture
DeepSeek R1-0528 shares the same underlying architecture as DeepSeek R1 and DeepSeek V3: a Mixture-of-Exports dense-attention model. It is initialized from DeepSeek V3-Base.
Reasoning Workflow
R1-0528 operates exclusively in thinking mode: all responses include chain-of-thought reasoning within ... tags before the final answer.
