What is Open-Weight AI?
Overview
Open-weight AI refers to models whose trained weights are released for others to download, inspect, fine-tune, or deploy. It matters because open weights can reduce vendor lock-in and enable private deployment, while still leaving open questions about licensing, safety, and true openness.
Why it matters
Open-weight models shape how companies balance control, cost, privacy, and frontier model access.
