GPT-5.5 Spud — OpenAI's Agentic Coding Upgrade Breakdown

OpenAI dropped GPT-5.5 today, codenamed Spud — and it just set a new state-of-the-art on Terminal-Bench 2.0 at 82.7%, narrowly beating Anthropic's unreleased Claude Mythos Preview. In this breakdown we cover what actually shipped, the benchmark headliners, the visual review loop that lets the model iterate on rendered output, how to use it in Codex today, why the API is not live yet, the cybersecurity guardrail story, how it stacks up against GPT-5.4, Claude Opus 4.5, and Gemini 3.1 Pro, and the honest limitations before you switch.
