Summary
DeepSeek-R1-0528 is an updated release of DeepSeek's R1 reasoning model, hosted on Hugging Face. This May 2025 update represents an incremental improvement to the frontier reasoning model with over 1 million downloads, featuring tool-calling capabilities and structured output support via inference providers.
Key Points
- •Updated version of DeepSeek's R1 reasoning/thinking model released May 28, 2025, with significant community adoption (1M+ downloads)
- •Supports structured output and is available through inference providers like Together AI with ~100 tokens/second throughput
- •Model includes chain-of-thought reasoning via <think> tags, with the chat template stripping reasoning traces from final output
- •Represents continued rapid capability advancement from a non-Western AI lab, relevant to tracking frontier model development timelines
- •Open-weights release on Hugging Face enables broad deployment and evaluation by the research community
