The U.S. government has cleared OpenAI's most advanced model for public release, marking a new phase in how Washington oversees powerful AI systems.
The U.S. Department of Commerce approved a broad launch of OpenAI's GPT-5.6 model, Axios reported Tuesday, citing a person familiar with the matter. OpenAI expects to release the model widely this week after additional testing and meetings between the company and government officials, according to the report.
"The additional testing gave the government confidence that the model's capabilities can be deployed safely," a person familiar with the discussions told Axios.
GPT-5.6 Sol, the flagship model in OpenAI's new lineup that also includes Terra and Luna, delivers improvements in coding, biology and cybersecurity tasks, the company said. OpenAI described Sol as its strongest model yet, though it said the model does not cross its internal "Cyber Critical" threshold — a benchmark the company uses to assess whether an AI system could independently carry out cyberattacks. The company acknowledged that benchmark tests cannot predict every possible use when the model is combined with other tools.
The approval caps a weeks-long review process that began with a limited preview. OpenAI initially released GPT-5.6 Sol to a small group of trusted partners whose participation was shared with the U.S. government, at the administration's request. The model was not available in ChatGPT during that preview period, and the company had not announced a general availability date until now.
Government oversight takes shape
The Trump administration has been building a framework for AI cybersecurity oversight. A June executive order said advanced AI can strengthen the country but also creates national security concerns requiring coordination across federal agencies and private companies. The White House fact sheet described the framework as voluntary for covered frontier models, stating it does not authorize mandatory licensing, pre-clearance or permits for releasing AI models.
OpenAI is not the only AI company to face government scrutiny over powerful models. In June, the U.S. government directed Anthropic to suspend access to its Fable 5 and Mythos 5 models by foreign nationals, forcing the company to disable the models more broadly to comply. The Commerce Department later lifted those export controls after Anthropic agreed to strengthen safeguards, work with the government on model-release protocols and report malicious activity tied to the models. Fable 5 was back online as of July 1.
The parallel cases highlight a shifting dynamic: the question is no longer just what AI models can do, but how quickly they should be released, who gets early access and what role the government should play.
What the approval means for investors
The green light for GPT-5.6 removes a key regulatory overhang for OpenAI and its partners. Microsoft, OpenAI's largest investor with more than $13 billion committed, stands to benefit from broader deployment of the model through Azure and Copilot products. Nvidia, whose H100 and B200 GPUs power the training and inference of frontier models, could see sustained demand as OpenAI scales GPT-5.6 access.
The approval also sets a precedent for how future frontier models may be reviewed. Anthropic's experience — restricted, then cleared after additional safeguards — suggests the government is developing a playbook: limited initial access, security review, then broader release. That pattern could become the standard for any company training models above certain capability thresholds.
For now, OpenAI's GPT-5.6 rollout this week will test whether the market's appetite for cutting-edge AI matches the regulatory machinery built to contain it.
