GPT-4o

Overview

OpenAI's omni-modal flagship model capable of processing and generating text, images, and audio natively. GPT-4o delivers GPT-4-class intelligence at significantly faster speeds and lower costs.

Why it matters

GPT-4o remains the model with the broadest capability surface area and the largest ecosystem of tools, plugins, and integrations built around it. Its native multimodal design — processing text, images, and audio in a single model rather than chaining specialists — simplifies architecture and reduces latency for complex applications. The ChatGPT consumer product runs on it, which means more real-world testing than any other model. For enterprise buyers, the OpenAI ecosystem (fine-tuning, batch API, assistants) provides the most mature production toolchain available.
