GPT-5.2

by OpenAI

GPT-5.2 is OpenAI's flagship model for coding and agentic tasks, with strong reasoning and a 272,000-token context window. It combines vision input, reasoning, tool use, and structured outputs for complex, multi-step workflows where the model plans, weighs alternatives, and takes actions. It is built for long-horizon problem-solving, code architecture work, and tool orchestration, performing well on tasks that need both reasoning and autonomous execution.

Get started

Call GPT-5.2 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.
