OpenAI began this Thursday the general rollout of GPT-5.6 Sol, its new artificial intelligence model, after receiving authorization from the Donald Trump Administration, which had limited its access for several weeks while various federal agencies evaluated its capabilities.
Until now, the model was only available to about twenty partners selected by the US government. With the Executive's approval, OpenAI has begun its release to all users.
54% More Efficient
OpenAI CEO Sam Altman stated in an interview with CNBC that GPT-5.6 Sol achieves 54% higher efficiency in token usage for AI agent programming tasks, an improvement that, according to the company, places the model at or above its main competitors.
"All companies are thinking about how much they spend and what value they get from artificial intelligence. That's exactly what we want to improve," Altman said.
Three Models with Different Cost Levels
GPT-5.6 is presented as a family composed of three models:
-
Sol, the most advanced model with the greatest capabilities.
-
Terra, a version oriented towards enterprise workloads with a lower cost.
-
Luna, designed for high-volume tasks, being the fastest and most economical option in the range.
With this strategy, OpenAI seeks to adapt its models to the different needs of companies and developers.
Weeks Under Government Supervision
The launch of GPT-5.6 was conditioned by a review process driven by the Trump Administration. As Altman explained, the authorization was the result of joint work with government officials, including Secretary of Commerce Howard Lutnick, Secretary of the Treasury Scott Bessent, and National Cybersecurity Director Sean Cairncross.
The CEO described the process as a collaboration in which federal authorities raised various technical and security questions that OpenAI resolved before expanding access to the model.
During that period, the Center for Artificial Intelligence Standards and Innovation at the Department of Commerce specifically evaluated GPT-5.6's capabilities in areas such as programming, biology, and cybersecurity.
A Precedent for AI Regulation
The initial limitation of access went beyond the voluntary framework of prior review of artificial intelligence models promoted by President Donald Trump on June 2. On this occasion, the US Government restricted the use of the model to a specific list of authorized organizations while the evaluation concluded.
Altman acknowledged that OpenAI does not consider this restricted access system sustainable as a permanent formula for future releases, although he defended the need to ensure security before making increasingly powerful models available to the public.
The company also maintains conversations with the US Administration regarding possible government participation in its shareholding, negotiations that, as Altman himself confirmed, remain open.
