About Phi-1.5
Phi-1.5 is a 1.3-billion parameter large language model (LLM) developed by Microsoft, designed to excel in complex reasoning tasks, particularly those requiring common sense, language understanding, and logical reasoning. Unlike many LLMs that heavily depend on web-scraped data, Phi-1.5 primarily uses a high-quality, synthetic dataset comprising about 30 billion tokens. This dataset is curated to resemble "textbook-like" content, concentrating on common sense and general knowledge, and sets the model apart. The Phi-1.5 architecture is a standard Transformer with 24 layers, 32 heads, and a head dimension of 64. It incorporates rotary embeddings and flash-attention for efficiency, utilizing a codegen-mono tokenizer.
