At the 2025 Worldwide Developers Conference, Apple introduced its new Foundation Models framework, which gives app developers direct access to the on-device foundation language model at the core of Apple Intelligence. The enhanced model is efficient for text generation with improved reasoning capabilities. The compact and approximately 3-billion-parameter model supports 15 languages and is specifically optimized for Apple silicon. This on-device infrastructure serves as a native foundation for the broader ecosystem of local LLMs for Microsoft Word, providing macOS users with a high-performance alternative to cloud-based AI plugins.
With GPTLocalhost, you can now effortlessly integrate Apple Intelligence directly into your Microsoft Word. Apple Intelligence provides complete data privacy and eliminates monthly cloud-based LLM subscription fees. Watch our demo video to see how easy and efficient it is in action, demonstrated on a 2020 MacBook Air (M1, 16GB) with Tahoe 26.0 beta. For more creative uses of local and private GPT models in Microsoft Word, explore additional demos available on our channel at @GPTLocalhost.
