About this version
Phi‑1 is a legacy model in the Copilot family that was released in 2023 as an early proof‑of‑concept with approximately 1.3 billion parameters. It was trained primarily on textbook-quality code and demonstrated strong performance on Python benchmark tasks, reportedly surpassing larger contemporaneous models in those evaluations. The model has since been superseded by later versions in the series.
