The U.S. Department of Commerce has officially lifted the restrictions on the release of OpenAI's advanced AI model GPT-5.6, approving its large-scale public promotion. This decision marks the official end of the previous temporary control measures imposed on the model.

OpenAI subsequently announced that the highly anticipated GPT-5.6 Sol model is currently in the final stage of preparation for launch and is expected to be available to the public this Thursday. At the same time, two other models, Terra and Luna, are also planned to be launched simultaneously.

Looking back, due to considerations of national security, the U.S. government had previously asked OpenAI to adopt a phased release strategy for GPT-5.6. Over the past month, the model's usage was limited to a small number of entities approved by the government. Although OpenAI had clearly stated that a phased release was not its preferred approach, the company has maintained active cooperation with regulators to comply with regulatory requirements.

According to informed sources, the complete lifting of the restrictions was made possible by a series of rigorous tests conducted by the AI Standards and Innovation Center under the U.S. Department of Commerce. During the testing period, OpenAI sent a team of technical experts to Washington, ready to respond to government officials' inquiries and needs at any time, ensuring efficient and smooth communication processes.

Currently, the U.S. government is preparing to issue a new AI executive order aimed at establishing a formal evaluation framework for the release of future advanced AI models. OpenAI stated that the company has fully coordinated with the government according to the current regulatory framework. With the removal of these restrictions, developers and the public will finally be able to access this new model, which serves as a practical test of the U.S. AI regulatory system.
