GPT-5.2 is OpenAI’s latest move in the agentic AI battle. According to OpenAI, its new model ‘hallucinates less’ and is more accurate than GPT-5.1. 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.” The company calls GPT-5.2 its “best model yet for everyday professional use” in a release, clearly coming for Gemini 3’s current reputation as a premier general-purpose model. OpenAI says the GPT-5.2 model series, which includes the Instant, Thinking, and Pro models, is better at “creating spreadsheets, building presentations, writing code, perceiving images, understanding long contexts, using tools, and handling complex, multi-step projects.”
