DeepSeek R1

by DeepSeek

DeepSeek R1 0528 is a major update to DeepSeek R1 released on May 28, 2025, adding system prompt support, JSON schema output, and native function calling for improved agentic compatibility. The model roughly doubles its reasoning token usage, averaging about 23K tokens per challenging problem versus 12K in the original, producing deeper chain-of-thought analysis and cutting hallucinations by 45 to 50% on rewriting, summarization, and reading comprehension tasks. Built on a 685-billion parameter MoE architecture with 37 billion active parameters, R1 0528 advances reasoning quality and approaches the performance of leading frontier reasoning models. It supports up to 163,840 tokens of context and outputs explicit thinking tokens for transparency. The model supports tool use and structured output via JSON schema, enabling multi-turn agentic workflows with improved reliability on complex tasks. Released under the MIT license, it remains fully open-source.
