Overview

• DeepSeek quietly launched R1-0528 on Hugging Face, labeling it a minor trial upgrade without issuing a public statement.
• LiveCodeBench benchmarks place the updated model just behind OpenAI’s o4-mini and o3 on code generation while outperforming xAI’s Grok 3 mini and Alibaba’s Qwen3.
• R1-0528 remains available under the MIT License, providing free access to model weights, documentation and commercial deployment rights.
• Independent tests by developers report the new iteration applies stricter filters on contentious political topics, making it the most censored R1 release yet.
• By narrowing the performance gap with paid models at minimal cost, DeepSeek’s open-source strategy intensifies the global AI competition with U.S. tech giants.
