- R · What Makes It Special
- Microsoft's Phi-4-mini (February 2025), a 3.8B-parameter dense decoder-only open model trained on 5T tokens of high-quality web and synthetic data, which Microsoft says matches models twice its size on math and coding tasks requiring complex reasoning; compared with Phi-3.5-mini it adds a 200K-token vocabulary for multilingual use and grouped-query attention, with better instruction following and function calling, 23 supported languages and a 128K-token context.
