GPT-5.2

GPT-5.2 is OpenAI's latest flagship AI model, released on December 11, 2025.^[1] Succeeding GPT-5.1, it is a family of three large language models within the GPT series. It comes in two modes: GPT-5.2 instant and GPT-5.2 thinking (with standard and extended thinking), with the latter being a reasoning model. A GPT-5.2 Pro model was released on the same day, which takes more reasoning time and compute than GPT-5.2 thinking.^[1]

Development and release

The release of GPT-5.2 occurred on December 11, 2025, approximately three weeks after the release of Google's Gemini 3 Pro, which had been widely cited as the leading multimodal model at the time.^[2] Media outlets reported that an internal "Code Red" memo,^[3][4] prompted by Gemini's dominance, was a key factor in accelerating the model's release from an originally planned late-December window.^[1] However, OpenAI executives disputed the narrative that the launch was solely reactive. Speaking to Wired, Fidji Simo, OpenAI's CEO of Applications, stated that the company had "been working on this model’s release for months", though she acknowledged that the "Code Red" and additional resources allocated to ChatGPT had been "helpful" in finalizing the deployment.^[5]

Microsoft announced that GPT-5.2 would be available in Microsoft 365 Copilot and Copilot Studio through a model selector, with a rollout expected to reach all Microsoft 365 Copilot license holders in the following weeks.^[6]

Architecture and capabilities

GPT-5.2 is designed to bring more economic value than previous models. It is better at spreadsheet creation, financial modeling, presentations, and multi-step project execution.^[7]

GPT‑5.2 comes in three modes; GPT-5.2 instant, GPT-5.2 thinking and GPT-5.2 Pro.^[8] Instant model is designed for speed and efficiency, and the other two models are reasoning models. GPT-5.2's Pro version comes into two separate selectors: standard and extended. These two modes are designed to use different compute times and powers.

Reception

VentureBeat noted that early reactions suggest that GPT-5.2 was "optimized for power users, developers, and enterprise agents rather than casual chat". Aaron Levie, CEO of Box, reported that the model scores "7 points better than GPT-5.1" on the company's tests for real-world knowledge work.^[9]
