OpenAI Launches GPT

The artificial intelligence (AI) sector experienced an important shift this week, as OpenAI released its highly anticipated GPT-5.6 models (Sol, Terra, and Luna) alongside its brand-new enterprise application, ChatGPT Work. The rollout followed a rigorous 12-day White House security review, representing the first time that a U.S. model has launched behind a government-vetted customer preclearance list. For investors tracking the space, this transition from chat-based systems to autonomous execution signals tailwinds for software, hardware, and automation indexes.
