GPT-4o

by OpenAI

The May 2024 release is the original GPT-4o, the version that introduced OpenAI's native omnimodal architecture reasoning across text, vision, and audio in a single model. It delivers strong performance on reasoning, mathematics, coding, and knowledge tasks, with vision input and function calling for tool use. The 128,000 token context window accommodates long documents, extended conversations, and detailed code analysis. This dated snapshot pins behaviour to the initial GPT-4o release, which is useful when you need a stable, reproducible baseline for production systems.

Get started

Call GPT-4o through the Opper gateway with one API key. Let your coding agent set it up, or call it directly — Opper is drop-in compatible with the OpenAI, Anthropic, and Google AI SDKs.

Set it up with your agent

Copy this and paste it into your coding agent — Claude Code, Cursor, Codex, and more — and it'll wire up Opper for you.
