On December 11 (local time), OpenAI unveiled its latest AI large-scale model, GPT-5.2, in a bid to counter the competitive pressure exerted by Google's Gemini 3. Earlier, confronted with the challenge from Gemini 3, OpenAI's CEO, Sam Altman, triggered the internal 'Red Alert' mechanism, channeling resources to enhance ChatGPT. GPT-5.2 has undergone thorough optimization for professional work environments, introducing three distinct versions: Instant, Thinking, and Pro. Each version is tailored to prioritize rapid response, in-depth work, and high-caliber problem-solving, respectively. OpenAI has claimed that GPT-5.2 surpasses its predecessors in tasks such as creating spreadsheets, crafting presentations, image perception, coding, and comprehending lengthy contexts. Altman noted that the real-world impact of Gemini 3 on OpenAI has been less significant than anticipated, and the company intends to deactivate the 'Red Alert' status in January of the following year.
