DeepSeek R1-0528 arrives in powerful open source challenge to OpenAI o3 and Google Gemini 2.5 Pro


Additionally, the model’s hallucination rate has been reduced, contributing to more reliable and consistent output.

The update adds support for JSON output and function calling, features that should make it easier for developers to integrate the model’s capabilities into their applications and workflows. Unlike the previous version, which required a special token at the start of the output to activate “thinking” mode, this update removes that need, streamlining deployment for developers. By combining measurable benchmark gains with practical features and a permissive open-source license, DeepSeek-R1-0528 is positioned as a valuable tool for developers, researchers, and enthusiasts looking to harness the latest in language model capabilities.
