Phi-3.5-Mini-Instruct

State‑of‑the‑art large language model useful on a variety of language understanding and generation tasks.

Phi‑3.5‑mini is a lightweight, state‑of‑the‑art open model built upon datasets used for Phi‑3 ‑ synthetic data and filtered publicly available websites ‑ with a focus on very high‑quality, reasoning dense data. The model belongs to the Phi‑3 model family and supports 128K token context length. The model underwent a rigorous enhancement process, incorporating both supervised fine‑tuning, proximal policy optimization, and direct preference optimization to ensure precise instruction adherence and robust safety measures.
