On December 12 (a Thursday), OpenAI made a significant announcement regarding the launch of its latest artificial intelligence model, GPT-5.2. This new iteration boasts remarkable enhancements in general intelligence, coding proficiency, and the ability to comprehend long-context scenarios. Just a few weeks earlier, Google had unveiled its much-anticipated Gemini 3, thereby placing OpenAI in a competitive landscape. OpenAI asserts that GPT-5.2 is poised to generate even greater economic value for its users, particularly excelling in tasks such as creating spreadsheets, constructing presentations, and managing intricate multi-step projects. Starting from that Thursday, the instant, thoughtful, and professional versions of GPT-5.2 will be progressively introduced in ChatGPT, with priority access granted to users subscribed to paid plans. Regarding pricing, GPT-5.2 imposes a charge of $1.75 per million input tokens and $14 per million output tokens. However, a 10% discount is available for cached inputs. Furthermore, OpenAI has clarified that it currently has no intentions of discontinuing the GPT-5.1, GPT-5, and GPT-4.1 models in its API offerings.
