This release follows Sam Altman's recent decision to accelerate development in reaction to Google's launch of Gemini 3 last month.

ChatGPT 5.2 matches or exceeds Gemini 3 Deep Think in coding and planning, so your projects move from idea to done. OpenAI GPT 5.2 adds

GPT-5.2 features a massive 400,000-token context window — allowing it to ingest hundreds of documents or large code repositories at once — and a 128,000 max output token limit, enabling it to generate extensive reports or full applications in a single go.

OpenAI says its AI tools now cut 40 to 60 minutes from daily work across many jobs. The claim comes from a new company survey run inside real workplaces, not from tests in labs. The data lands at a tense moment,

The SWE-Bench Verified evaluation is basically a test of AI processing accuracy. It measures how well the AI solves a set of coding problems. According to OpenAI, GPT-5.1-Codex-Max "reaches the same performance" as the previous model, GPT-5.1-Codex.

Olivier Godement points to coding, customer support, and life sciences as key areas where AI can automate jobs. In a recent podcast, Godement emphasized the efficiency which AI brings to tasks like dr
