What is Phi 4?
Tavory's live catalog currently lists Phi 4 from Deepinfra. The catalog describes it as phi-4-reasoning-plus is an enhanced 14b parameter model from microsoft, fine-tuned from phi-4 with additional reinforcement learning to boost accuracy on math, science, and code reasoning tasks. it uses the same dense decoder-only transformer architecture as phi-4, but generates longer, more comprehensive outputs structured into a step-by-step reasoning trace and final answer. while it offers improved benchmark scores over phi-4-reasoning across tasks like aime, omnimath, and humanevalplus, its responses are typically ~50% longer, resulting in higher latency. designed for english-only applications, it is well-suited for structured reasoning workflows where output quality takes priority over response speed..
