OpenAI GPT-5.6 Models launch after US security review, introducing new AI capabilities while addressing concerns over cybersecurity risks

OpenAI is set to release its latest artificial intelligence models, the GPT-5.6 series, to the public after completing security discussions with US authorities over concerns surrounding advanced AI capabilities and potential cyber risks.

The ChatGPT maker announced that GPT-5.6, alongside its new Sol, Terra and Luna model tiers, would be launched globally on Thursday, 9 July 2026, following a period of restricted access granted to selected US-based partners.

OpenAI said the limited preview was provided in late June after requests from Washington for additional assessment of the technology’s capabilities before a wider rollout.

“GPT-5.6 Sol, along with Terra and Luna, will launch publicly this Thursday. We’re expanding preview access globally now,” OpenAI said in a statement shared on X.

The new model family has attracted attention because of concerns that highly advanced AI systems could identify weaknesses in computer code that malicious actors might exploit.

Security experts and policymakers have increasingly focused on the potential risks associated with powerful AI tools capable of complex reasoning and technical analysis.

US technology outlet Axios reported that the administration of President Donald Trump had approved the broader release following technical evaluations and meetings between OpenAI representatives and government officials.

OpenAI, the White House and the US Department of Commerce had not publicly confirmed details of the report at the time of publication.

GPT-5.6 will be available in three versions designed for different user needs. Sol will serve as the company’s flagship model, Terra will target everyday professional and business applications, while Luna will offer a faster and lower-cost option for users seeking efficient AI assistance.

The release follows similar developments involving Anthropic, OpenAI’s major competitor in the artificial intelligence sector.

Anthropic recently announced plans to restore access to some of its most advanced models after restrictions on their availability were eased by Washington.

The US government has been developing new criteria for determining which AI systems may require additional security controls under an executive order focused on artificial intelligence risks.

OpenAI has previously raised concerns about extensive government involvement in AI releases, arguing that long-term restrictions could limit access to important technologies for businesses, researchers and everyday users.

The company said it was working with US officials to develop a cybersecurity framework and a consistent process for evaluating future AI model launches.

The release of GPT-5.6 comes as competition intensifies among leading AI companies, including OpenAI, Anthropic and Google, as they race to develop more capable artificial intelligence systems.

OpenAI has also indicated that Terra will be priced below its predecessor, GPT-5.5, as the company seeks to expand adoption among businesses and consumers.

The growing commercial importance of artificial intelligence has pushed major AI firms towards ambitious expansion plans, with reports indicating that OpenAI and Anthropic have filed confidential documents with US regulators ahead of possible public listings at valuations approaching $1 trillion.
