CNBC’s MacKenzie Sigalos reports on OpenAI’s latest salvo against Alphabet, using its new Disney partnership to drive adoption while shipping GPT-5.2 to drive its enterprise business.

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 latest model, GPT 5.2, was shown to outperform industry professionals in specific tasks across 44 different occupations.

OpenAI announced today that it's launching GPT-5.2, the newest model in its GPT-5 series. The new model will start rolling out immediately, with paid ChatGPT customers getting access first.

The ChatGPT parent still accounts for most of the software company’s revenue backlog.

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.”

"​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."

OpenAI has released GPT-5.2, which aims to be ChatGPT's "most capable model series yet for professional knowledge work."
