Explore the engineering and design principles behind integrating generative capabilities seamlessly across an entire operating system—from system-wide writing tools to playful visual creation like Genmoji and Image Playground. Attendees will gain insight into how deep collaboration between engineering and human domain experts (writers, designers, and artists) sets the benchmark for quality, privacy, and taste, turning raw models into intuitive, delightful everyday tools. Key Takeaways for Attendees: How to approach AI product development from a customer-experience-first perspective rather than tech-for-tech’s-sake. The systems-engineering and API considerations required to weave intelligent tools natively across an entire platform. Why human expertise, evaluation, and craftsmanship are essential to building trustworthy and expressive generative features.
