Today’s trending AI news stories

OpenAI launches GPT-5.2 and scores a $1B Disney deal

OpenAI has officially launched GPT-5.2, a three-tier model lineup: Instant, Thinking, and Pro, pushing AI reasoning, coding, math, and visual comprehension to new heights.

GPT-5.2 outperforms human experts on 4–8 hour tasks 71% of the time, according to the new GDPval score.

GPT-5.2 Thinking outperformed human benchmarks on GDPval while cutting hallucinations by 38 percent versus GPT-5.1. The Pro model tackled a simplified open problem in statistical learning theory without human guidance. Visual reasoning and coding saw major gains, from parsing low-resolution motherboard images to scoring 80 percent on SWE-Bench Verified. Developers gain efficiency through OpenAI’s new response-caching system.

A day prior to the release, the company warned that next-gen AI poses “high” cybersecurity risks, from zero-day exploits to industrial intrusions. OpenAI is responding with the Frontier Risk Council, a security expert advisory group overseeing safeguards and frontier-capability risks.

OpenAI also just struck a three-year $1 billion licensing and equity deal with Disney, letting over 200 Disney, Pixar, Marvel, and Star Wars characters appear in Sora and ChatGPT Image. Nicholas Grous of Ark Invest called it a potential dividing line in entertainment: “We're not just going to want to be fed AI slop for 16 hours a day.” Bob Iger emphasized the initiative “does not in any way represent a threat to the creators at all,” noting that name, likeness, and voices are excluded. Disney will curate promising AI-generated content for Disney+, creating a feedback loop between fan creativity and premium production.

Meanwhile, ChatGPT’s long-awaited “adult mode” is slated for Q1 2026, using a tested age-prediction model to keep minors out. The company is also currently facing internal tension as staff like Tom Cunningham leave, allege that the company’s economic research is drifting into AI advocacy. Cunningham reportedly struggled to publish research on AI’s negative economic impacts, including job displacement. Chief strategy officer Jason Kwon defended the approach, stating the company must not only identify risks but actively “build the solutions. Read more.

Google debuts updated Deep Research Agent amid GPT-5.2 release 

Gemini 3 Pro has leapt in real-world reliability, scoring 69 percent trust in the HUMAINE benchmark versus 16 percent for Gemini 2.5. Blind, multi-turn testing with 26,000 participants revealed gains in reasoning, adaptability, and ethics. Complementing this, Google and Kaggle’s FACTS suite shows AI factuality still caps near 70 percent, with Gemini 3 Pro leading. Gemini 3 now powers AI Mode in Search, Stitch for interactive app prototypes, and TTS models that provide natural speech across multiple voices and languages.

Google launched an upgraded Deep Research Agent, on the same day OpenAI dropped GPT-5.2. The autonomous research agent is built on Gemini 3 Pro and accessible to developers via the new Interactions API. It has also integrated Anthropic’s Model Context Protocol (MCP) into its cloud, letting AI models natively access tools like Maps, BigQuery, Compute Engine, and Kubernetes without custom interfaces. On the web, Google rolled out Disco, which turn browser tabs into handy mini-apps for research, planning, and prototyping.

Meanwhile, Disney sent a cease-and-desist over alleged large-scale copyright infringement by Gemini AI, citing unauthorized reproduction of characters across Frozen, Star Wars, and Marvel franchises. Read more.
