OpenAI Unveils GPT-5.2, Boosting Reasoning, Memory, and Reliability

OpenAI Introduces GPT-5.2

OpenAI has released GPT-5.2, the newest generation of its large‑language model, and made it accessible through the ChatGPT interface and the API. The update arrives shortly after the earlier GPT‑5.1 release and shifts focus from restoring personality to delivering concrete technical improvements.

Enhanced Reasoning and Task Handling

The core advance of GPT-5.2 lies in its ability to break down complex queries into manageable steps, plan a solution path, and present coherent answers. This multi‑step reasoning capability enables the model to tackle professional‑level tasks such as spreadsheet creation, presentation design, and intricate analyses, often matching or surpassing top human experts in a wide range of categories.

Expanded Memory for Long‑Form Context

GPT-5.2’s memory has been dramatically enlarged, allowing it to retain context across “hundreds of thousands of words.” Users can upload extensive documents, project folders, legal contracts, scientific papers, or multiple files, and the model will keep track of details throughout the interaction. This upgrade facilitates comparative analyses of multiple readings, financial trend assessments, and other multi‑document workflows that previously overwhelmed earlier versions.

Improved Vision and Understanding of Visual Data

Alongside textual upgrades, the model’s vision capabilities have been refined. GPT-5.2 can interpret charts, diagrams, and complex images with greater accuracy, extracting details that were previously difficult to discern.

Reliability Gains and Hallucination Reduction

OpenAI reports a notable drop in hallucinations—about a 30 % reduction compared with GPT‑5.1—making the model more dependable for real‑world applications. The system also demonstrates stronger tool‑use reliability, successfully handling intricate customer‑service scenarios involving multiple variables such as flight delays, overnight stays, and special seat requests.

Tiered Offerings and Rollout Strategy

GPT-5.2 is offered in three tiers—Instant, Thinking, and Pro—each scaling in capability. The model is being introduced gradually across OpenAI’s subscription tiers, including Plus, Pro, Go, Business, and Enterprise plans, with the older GPT‑5.1 access slated to phase out in the coming months.
