GPT‑4o

OpenAI’s Omnimodal Flagship Model

What is GPT‑4o?

‍ GPT‑4o (“o” for omni) is OpenAI’s most advanced and unified multimodal model, capable of understanding and generating text, vision, and audio, all in real-time. It builds on the foundation of GPT‑4 Turbo, but delivers faster response times, lower cost, and new modalities in a single, end-to-end neural network.

Launched in May 2024, GPT‑4o represents a major leap toward human-like interaction, enabling natural voice conversations, image understanding, and dynamic assistant behavior, all accessible through OpenAI’s API and ChatGPT.

Key Features of GPT‑4o

Multimodal Input & Output

Accepts and generates text, images, audio, and more, seamlessly across formats.

Real-Time Speed

Faster than GPT‑4 Turbo in both latency and throughput, even under load.

Lower Cost, Greater Access

Cheaper to use than GPT‑4 Turbo, while offering higher quality responses.

Live Voice Capabilities

Engage in natural voice chats with emotion, pauses, and human-like rhythm.

Vision Understanding

Describe, interpret, and analyze images or screenshots with context awareness.

Top-Tier Reasoning

Performs strongly across coding, math, science, writing, and logic tasks.

Use Cases of GPT‑4o

Build apps that talk, see, and respond in real time using voice, vision, and text.

Upload images, charts, screenshots, and get instant and accurate interpretations.

Power conversational agents in phones, kiosks, or smart assistants.

Deliver empathetic, fast, and helpful interactions in multiple formats.

Combine text, voice, and visual inputs for ideation, design, and storytelling.
