Summary
Chinese startup DeepSeek has released an updated version of its open-source reasoning AI model, DeepSeek-R1-0528, which brings it closer to proprietary paid models such as OpenAI’s O3 and Google Gemini 2.5 Pro in terms of reasoning capabilities.
The model is now available under the MIT License, allowing developers to customise the model to their needs and supporting commercial use.
It delivers stronger performance on complex reasoning tasks in mathematics, science, business and programming, while also including new features to make it easier for developers to integrate the model’s capabilities.
There is also a smaller variant of the chain-of-thought reasoning model for those with more limited compute budgets.
