OpenAI is preparing to launch its most advanced artificial intelligence model, GPT-5.6, following a month-long delay linked to national security reviews by the United States government. The highly anticipated release is expected to mark another major step in the rapidly evolving AI industry.
The company is scheduled to introduce the flagship GPT-5.6 Sol model along with two more affordable versions named Terra and Luna. The announcement was made by the ChatGPT developer, which confirmed the public rollout after completing the required review process.
The launch had originally been planned earlier but was postponed after US officials requested additional time to evaluate the technology. The government wanted to assess whether advanced AI systems could pose national security risks or be misused for harmful purposes.
Before the wider release, OpenAI provided access to GPT-5.6 only to a limited number of approved partners. This restricted rollout allowed testing while government agencies examined the model’s potential impact.
US authorities have increased oversight of advanced artificial intelligence systems due to concerns that they could be used to conduct sophisticated cyberattacks against critical infrastructure. Officials have also expressed concerns about the possible military and intelligence applications of next-generation AI models.
The delay reflects the growing global competition in artificial intelligence, particularly between the United States and China. Both countries continue investing heavily in AI technologies as they compete for leadership in one of the world’s fastest-growing industries.
Reports suggest Chinese authorities are also considering tighter controls on overseas access to their future AI models. These discussions show how AI has become an important geopolitical issue beyond its commercial applications.
The latest development comes as governments around the world introduce stronger regulations for advanced AI technologies. Policymakers are attempting to balance innovation with safety by ensuring powerful models are deployed responsibly.
OpenAI is not the only AI company facing increased regulatory scrutiny. Rival AI developer Anthropic recently experienced restrictions on two of its advanced models following a US export control order.
Anthropic later restored broader access to one of its AI systems after introducing stronger safety measures. However, another cybersecurity-focused model remains restricted because of concerns it could be used to identify and exploit software vulnerabilities.
According to reports, the Trump administration approved the wider release of OpenAI’s new AI models after extensive discussions with company executives and government officials. The approval followed detailed testing and safety evaluations.
The decision also aligns with a recent executive order introducing a voluntary 30-day government review period for advanced AI models before they become publicly available. The policy aims to strengthen oversight while allowing innovation to continue.
Competition within the AI sector is also intensifying. Billionaire Elon Musk announced that his AI company, SpaceXAI, plans to release its flagship Grok 4.5 model, adding further momentum to the race among leading AI developers.
