OpenAI's New AI Model: US-Only Preview & Security Concerns

OpenAI has launched a U.S.-only preview of its new AI model series to a limited group of partners. This action comes at the request of the U.S. government. This follows a White House order two weeks ago for OpenAI's rival, Anthropic, to ban all foreign nationals from accessing its Fable 5 and Mythos 5 models due to national security concerns. Anthropic shut down access, stating it could not reliably comply. These new AI models, like Anthropic's Mythos series and now OpenAI's GPT-5.6, raise concerns about their ability to identify software vulnerabilities. OpenAI briefed the U.S. government on its new models' capabilities before the launch. The company stated it is uncomfortable with this process, saying it keeps powerful tools from users and partners who need them. OpenAI is taking this short-term step for broader availability soon. The GPT-5.6 series includes three new models: Sol, Terra, and Luna. This situation highlights the growing tension between AI development and national security concerns.
