OpenAI's GPT-5.6 Models Launch with Restricted Access for Government Vetting

OpenAI has commenced the rollout of its highly anticipated GPT-5.6 series, introducing three new artificial intelligence models: Sol, Terra, and Luna. Sol is positioned as the flagship model, designed for advanced capabilities, while Terra is a balanced model for everyday tasks, and Luna offers a faster and more affordable option. However, the initial availability of these powerful new AI systems is not for the general public. OpenAI has confirmed that access is currently limited to a small group of "trusted partners" who have received approval from the U.S. government. This unprecedented restriction is a direct response to a request from the Trump administration. The government's involvement stems from an executive order signed earlier in June by President Trump, which established a framework for federal review of advanced AI models. The aim is to assess potential national security risks, particularly those related to cybersecurity, before these technologies are widely released. Concerns have been heightened following previous incidents, such as Anthropic's Mythos model demonstrating capabilities in finding software flaws that could be exploited by malicious actors. OpenAI stated that while it believes in broad access to its tools, it is complying with the government's request as a temporary step. The company views this limited preview period as a necessary phase for testing and coordination with partners, with a broader public release expected in the coming weeks. The company also expressed a sentiment that such government approval processes should not become the long-term default, as it could hinder wider adoption and innovation. This move by OpenAI follows similar actions taken against rival AI developer Anthropic, which had to pull two of its new AI models, Fable 5 and Mythos 5, from public access earlier this month due to a Trump directive. The current situation highlights a growing trend of government oversight and scrutiny over the development and deployment of cutting-edge AI technologies, especially those with significant potential impact on national security and critical infrastructure.
