OpenAI Releases GPT-5.2, Google Powers US Military AI Platform

According to Last Week in AI’s newsletter #329, OpenAI has released GPT-5.2, described as the company’s “latest move in the agentic AI battle.” The publication positions this release within the competitive landscape of AI systems capable of autonomous task completion.

In parallel developments, Google is reportedly powering a new US military AI platform called GenAI.mil, according to the newsletter. This marks a significant intersection of commercial AI capabilities and defense applications.

Additionally, the newsletter reports that the Trump administration is taking steps to prevent states from independently regulating artificial intelligence. This federal action suggests an effort to centralize AI governance and could impact how AI development and deployment are overseen across different jurisdictions.

The newsletter, published by Last Week in AI, aggregates these three major developments in the AI industry spanning corporate product releases, military technology partnerships, and regulatory policy shifts. These stories collectively illustrate the diverse arenas—commercial, defense, and governmental—where AI technology continues to evolve and generate policy discussions.
