Microsoft brings OpenAI’s smallest open model to Windows users
Microsoft is integrating OpenAI’s new free and open GPT-OSS-20B model into Windows 11 via Windows AI Foundry. The lightweight, tool-savvy AI, optimized for code execution and agent tasks, runs on PCs with at least 16 GB of VRAM. Text-only but prone to hallucinations, it’s aimed at autonomous assistants and real-world workflows. Microsoft plans macOS support soon and hosts the model on Azure AI Foundry and AWS.
