- R · What Makes It Special
- Microsoft's Phi-4-reasoning-plus (April 30, 2025), a 14B-parameter open reasoning model made by supervised fine-tuning of Phi-4 on curated 'teachable' prompts with reasoning traces from o3-mini, then a short phase of outcome-based reinforcement learning that produces longer reasoning chains; Microsoft says it outperforms much larger open models such as DeepSeek-R1-Distill-Llama-70B and approaches the full DeepSeek-R1 on math, science, coding and planning. 32K-token context; MIT license.
