- R · What Makes It Special
- DeepSeek's DeepSeek-R1-0528, a May 28, 2025 upgrade of its open-weight DeepSeek-R1 reasoning model: more compute and algorithmic optimizations in post-training deepened its reasoning (about 23K tokens per AIME question, up from 12K), lifting AIME 2025 accuracy from 70% to 87.5% and bringing it close to o3 and Gemini 2.5 Pro; it also cut hallucinations, improved front-end coding, added system-prompt support, JSON output and function calling, and was distilled into DeepSeek-R1-0528-Qwen3-8B.
