OpenAI said its new model outperforms those from rivals Google and Anthropic across a wide range of evaluations.

On Thursday, OpenAI released GPT-5.2, its newest family of AI models for ChatGPT, in three versions called Instant, Thinking, and Pro. The release follows CEO Sam Altman’s internal “code red” memo earlier this month, which directed company resources toward improving ChatGPT in response to competitive pressure from Google’s Gemini 3 AI model.

OpenAI just launched GPT-5.2, a frontier model aimed at developers and professionals, pushing reasoning and coding benchmarks as it races Google’s Gemini 3 while grappling with compute costs and no generator.

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 launches GPT-5.2 after code red, boosting productivity with improved reasoning, tools, and enterprise-focused capabilities.

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.”

OpenAI said the results suggest the model can meaningfully assist professional workflows when paired with human oversight, rather than fully replacing workers.

OpenAI plans to launch an 'adult mode' for ChatGPT in early 2026, allowing verified adult users more freedom in interactions. Age verification is rolling out to ensure minors are blocked from mature content.

OpenAI says that Dresser will be responsible for the company's revenue strategy in enterprise and customer success.
