GPT-5.2: OpenAI’s Powerful New AI Model
Company Claims: New AI Tops Gemini, Matches Humans on 70% Work Tasks
OpenAI recently launched its most advanced AI model, GPT-5.2, designed specifically for professional work. It includes versions like GPT-5.2, GPT-5 Thinking, and GPT-5 Pro. This launch happened on December 11, 2025. The release came after CEO Sam Altman’s internal “code red” alert to compete with Google’s Gemini 3 model. It focuses on big improvements in math, science, coding, imaging, complex tasks, and accuracy.
Key Features
GPT-5.2 handles a huge 400,000-token context window, meaning it can analyze hundreds of documents at once, with knowledge up to August 31, 2025. Hallucinations—where AI makes up false info—dropped a lot, from 16.8% in the previous version to 10.9%, and even to 5.8% with web access. It matches human performance on 70% of work tasks like spreadsheets, presentations, and multi-step projects, making it very useful for jobs.
Paid ChatGPT users and developers can access it right away through the app or API. New features include better handling of sensitive questions, warmer responses, and early safety checks for age prediction.
What Are AI Hallucinations?
In AI, hallucinations mean the model creates incorrect or made-up information that sounds real, like false facts or nonsense answers. This happens due to flawed training data, biases, or misunderstanding patterns, similar to seeing shapes in clouds. GPT-5.2 cuts this error rate sharply for more reliable outputs.
