Microsoft has integrated OpenAI’s GPT model, gpt-oss-20b, into its Windows AI Foundry platform, allowing Windows 11 users to access advanced AI capabilities from their desktops. The model is optimized for agentic tasks and is compatible with consumer PCs and laptops with a minimum of 16GB of VRAM. gpt-oss-20b is a text-only model with a 53% hallucination rate on OpenAI’s PersonQA benchmark. Microsoft plans to extend its availability to macOS and other devices, and both gpt-oss-20b and its predecessor will be accessible through Microsoft’s Azure AI Foundry and Amazon’s AWS.
