Phi 4 reasoning plus

Phi-4-reasoning-plus is an open-weight reasoning model derived from Phi-4, trained with chain-of-thought supervised fine-tuning and extra reinforcement learning on high-quality synthetic and filtered public-domain data (math, science, coding) with safety alignment. It delivers stronger reasoning in a small model, at the cost of ~50% longer outputs and higher latency.
