OpenAI Lifts Hold on GPT-5.6 Model, Ending Weeks of Delay

After weeks of holding back its most powerful model, OpenAI is set to release the GPT-5.6 globally this Thursday. The company’s models, known as Luna, Sol, and Terra, will be available worldwide on the same day. This decision marks a significant shift in the company’s stance following concerns raised by the Trump administration about the potential for cyberattacks using these advanced AI systems.

The hold was initially imposed at the request of the White House, which had asked OpenAI to stagger its release due to fears over the model’s capabilities. The company complied with this request and offered GPT-5.6 to a small group of partners in collaboration with the government. This move came after the Trump administration introduced far more restrictive export controls on Anthropic, a competitor of OpenAI.

The restrictions imposed by the White House were part of an executive order signed by President Donald Trump establishing a voluntary vetting regime for AI systems. While initially praised by industry leaders, this move was met with criticism from AI safety advocates due to its light-touch approach. The critics argued that such measures would not be sufficient to address the risks associated with advanced AI models.

OpenAI’s decision to release GPT-5.6 widely comes after a month of previewing and testing the model with the White House and the Center for AI Standards and Innovation. This collaboration, though voluntary, reflects the company’s efforts to work closely with regulatory bodies on safety testing and reviews before deploying its models broadly.

A spokesperson for OpenAI emphasized that while government approval was not technically necessary, the company had been actively engaging with the administration on these matters. The White House has signaled its comfort with OpenAI’s plan to release GPT-5.6 more widely once this testing process is complete.

The recent developments in AI regulation have created uncertainty within the industry. The sweeping export controls placed on Anthropic’s Fable 5 and Mythos 5 models were lifted last week after two weeks of drama and debate over how to govern cutting-edge AI systems. OpenAI had initially stated its intention to comply with these regulations, but expressed concerns about making government access a long-term default.

In a June press release, the company noted that it would temporarily comply with the administration’s request for a staggered release in order to ensure broader availability of GPT-5.6 in the coming weeks. However, OpenAI also emphasized its reservations about this process becoming the standard approach for future model releases.
