What are the main capabilities of GPT-4o?

GPT-4o is a multimodal model that processes text, vision, and audio in a single network. It features a standout voice mode with low-latency, expressive, and interruptible speech.

How much does GPT-4o cost?

GPT-4o operates on a freemium model with pricing tiers of $10 for Basic, $30 for Pro, and contact sales for Enterprise.

Is GPT-4o suitable for long-document analysis?

It is not ideal for very long documents because its context window is smaller than Claude's. It may also hallucinate sources more readily during careful citation work.

Where is GPT-4o available?

GPT-4o is the default model in ChatGPT for most users and is available via API, Copilot, and a massive plugin and connector ecosystem.

In short

GPT-4o is OpenAI's flagship multimodal model that handles text, vision, and audio in a single network. It is best for users seeking a reliable, all-in-one assistant within the ChatGPT ecosystem, particularly for its low-latency voice mode.

Best for

Pick GPT-4o when you want one assistant that does text + image + voice well, and you live inside the ChatGPT ecosystem already.

Skip if

Skip it for long-document work where Claude's context shines, or when you need a tightly-controlled brand voice.

GPT-4o ("omni") is OpenAI's flagship multimodal model — text, vision, and audio in a single network. It's the default model in ChatGPT for most users and the most-deployed frontier model overall thanks to API ubiquity and a massive plugin/connector ecosystem.

Its standout feature remains the voice mode — low-latency, expressive, interruptible speech that feels closer to a phone call than a chatbot. Vision is strong out of the box. For general writing, coding, and analysis, it's a credible default — the kind of tool that's never the wrong choice even when something else might be marginally better for a specific task.

Where it slips is on very long documents (context is smaller than Claude's), on careful citation work (it hallucinates sources more readily), and on stylistic nuance (the default voice is competent but generic without nudging).

Editor's take

GPT-4o is the safest "never-wrong" choice on this list. It's rarely the best at any one thing now that the frontier has multiple competitors, but the breadth and the ecosystem keep it as the AI most teams will actually use day-to-day.
