// MODEL OPTIMIZATION AND PROMPT SYNTAX TERM
Phi
Phi is a series of small, high-performing AI models from Microsoft that are surprisingly capable despite their compact size, often trained on carefully curated data.
TECHNICAL DEFINITION
Phi is a family of small language models developed by Microsoft, specifically designed to achieve strong reasoning capabilities with significantly fewer parameters than larger models, often through high-quality, synthetic data training and focusing on common sense reasoning and language understanding.
BACKGROUND
In machine learning, reinforcement learning from human feedback (RLHF) is a technique to align an intelligent agent with human preferences. It involves training a reward model to represent preferences, which can then be used to train other models through reinforcement learning.
