1) GPT-5.2 Raises the Bar for Professional AI

OpenAI launched GPT-5.2, its most advanced frontier model yet, built for deep professional work and long-running agents. Early results show it outperforming industry experts across tasks like coding, spreadsheets, research, vision analysis, and tool-driven workflows—often faster and cheaper. With stronger long-context reasoning, lower hallucination rates, and state-of-the-art agentic coding, GPT-5.2 is rolling out across ChatGPT (Instant, Thinking, Pro) and is now live in the API for developers.

2) Disney Partners with OpenAI to Bring Iconic Characters to Sora

The Walt Disney Company and OpenAI announced a landmark three-year licensing deal making Disney the first major content partner for Sora. Fans will be able to create short AI-generated videos using 200+ characters from Disney, Pixar, Marvel, and Star Wars, with curated content appearing on Disney+. Disney will also use OpenAI’s APIs internally and invest $1B in OpenAI, signaling a major step toward responsible, licensed AI storytelling in entertainment.

3) Third-Party Breach Exposes ChatGPT API Account Metadata

OpenAI confirmed a data exposure linked to a third-party analytics provider, Mixpanel, affecting some ChatGPT API users. While no chat content, passwords, or API keys were leaked, exposed data included names, emails, organization IDs, and technical metadata—raising phishing risks. The incident highlights growing concerns around vendor security as AI platforms scale. OpenAI has cut off the affected service and urged users to strengthen account security practices.
