GPT-4o
OpenAI's optimized multimodal model offering GPT-4 intelligence at faster speeds and lower costs.
Definition
GPT-4o (the "o" stands for "omni") is OpenAI's flagship model released in May 2024, designed for seamless multimodal interaction across text, audio, and vision. It processes and generates content across all modalities natively, rather than using separate models.
GPT-4o matches GPT-4 Turbo's intelligence while being 2x faster and 50% cheaper, making advanced AI more accessible for production applications.
Why It Matters
GPT-4o's speed and cost improvements make real-time AI applications practical—voice assistants that respond naturally, live video analysis, and interactive AI experiences that weren't economically feasible before.
For businesses, it means GPT-4-level capabilities at price points that enable broader deployment.
Examples in Practice
A customer service platform uses GPT-4o for real-time voice conversations with callers, handling complex inquiries with natural speech patterns and instant responses.
An e-commerce company uses GPT-4o to provide live video shopping assistance, with AI analyzing products shown on camera and answering questions conversationally.
