OpenAI launched GPT-5.2, a new version designed to strengthen ChatGPT's performance amid increasingly tough competition in the world of artificial intelligence.
The update arrives after rival models such as Gemini 3 (Google) and Grok 4.1 gained ground in key tasks. This situation led Sam Altman to declare an internal "code red" to accelerate improvements, according to OpenAI's own CEO.

GPT-5.2: OpenAI's response to its competitors
The company describes GPT-5.2 as "the best model so far for daily professional use." The goal is clear: regain an edge over Google's and xAI's offerings.
Although Altman clarified that the model had been in development for months, the launch was moved up to compete head-on in an increasingly demanding market.
More context and better reasoning
One of the strongest improvements is the expansion of the context window, which now reaches around 400,000 tokens. This allows users to work with hundreds of documents or large code repositories in a single session.

In addition, GPT-5.2 incorporates more robust chain-of-thought reasoning, inherited from previous models, which improves its performance in programming, complex calculations, and structured tasks.
Which tasks GPT-5.2 improves
With this update, models based on GPT-5.2 excel at creating spreadsheets, presentations, writing code, interpreting images, and managing projects with multiple steps.

The three versions of the new model
The GPT-5.2 family includes three variants: Instant, Thinking, and Pro. The latter is aimed at professional users seeking maximum quality and reliability.
GPT-5.2 Thinking showed clear improvements over its predecessor, with fewer "hallucinations." It even managed to achieve a 100% score on the AIME 2025 test, according to data released by OpenAI.
Availability in ChatGPT
OpenAI reported that GPT-5.2 is now available in ChatGPT for users with paid plans, such as Plus, Pro, Business, and Enterprise.
