Frequently Asked Questions
What is GPT‑5.2, and when was it released?
OpenAI announced GPT‑5.2 on 11 December 2025 as an update to the GPT‑5 model family focused on coding, long‑context work, and “knowledge‑work” outputs. It is rolling out across ChatGPT and the OpenAI API in Instant, Thinking, and Pro variants.
Which GPT‑5.2 model name should developers use in the OpenAI API?
OpenAI lists gpt-5.2 as the primary API model name, with gpt-5.2-chat-latest for the chat‑aligned variant and gpt-5.2-pro for the higher‑cost Pro tier. For reproducibility, the docs also list a dated snapshot such as gpt-5.2-2025-12-11.
What does a 400,000‑token context window change in practice?
A larger context window lets you keep more code, specs, and logs in one session, which can reduce time spent re‑pasting or re‑summarizing. It still rewards structure: provide the most relevant files and constraints first, then validate outputs with tests and code review.
Is GPT‑5.2 available in GitHub Copilot?
GitHub announced a public preview on 11 December 2025 for Copilot Pro, Pro+, Business, and Enterprise. GitHub also lists Visual Studio Code 1.104.1 (or later) as the minimum version for access in VS Code, and notes that rollout is gradual.
