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.

The new, productivity-focused GPT-5.2 model comes as the AI company faces increasing competition from Google and Anthropic.

GPT-5.2 is here, and with it, OpenAI wants “to unlock even more economic value for people,” Fidji Simo, the company’s CEO of Applications, told reporters in a Thursday briefing. She said it’s been in the works for “many, many months.”

For the first time, developers can embed Google's Deep Research tool, based on Gemini 3 Pro, into their own apps.

"​I think the reason this bidding is approaching $100 billion-plus is the content library and the potential to do a Disney-OpenAI type of deal."

Today, OpenAI launched GPT-5.2, touting its stronger safety performance in regard to mental health.
