GPT-5.6 Launch: OpenAI Addresses US Security Concerns

OpenAI is set to launch its most advanced AI model, GPT-5.6 Sol, along with new Terra and Luna models. This comes after a delay due to US government national security concerns. Experts have warned that advanced AI models could speed up sophisticated cyberattacks. Washington has been increasing its scrutiny of powerful AI releases. Axios reported that the Trump administration approved the broad release of GPT-5.6 after more testing and discussions between OpenAI and government officials. Competitor Anthropic had temporarily disabled its Mythos 5 and Fable 5 models following a US government export control order. That order was lifted once safeguards were put in place. Previously, OpenAI gave a small group of vetted partners access to GPT-5.6, and their details were shared with authorities. This ongoing situation highlights the tension between AI development and national security.
