GPT-4o: Omni Model
What Happened
OpenAI released GPT-4o ('omni'), a unified model that natively processed text, audio, images, and video with near-instant response times. It could hold natural voice conversations with emotional expression, sing, laugh, and respond to visual input in real time.
Why It Mattered
Made multimodal AI interaction feel dramatically more natural and immediate. The voice demo went viral because it suggested a future where AI assistants felt less like text interfaces and more like responsive, ambient computing systems.
