OpenAI will launch the GPT-5.6 model, previously postponed at the request of the US government due to security concerns.

OpenAI has received approval from U.S. authorities for the wide-scale launch of GPT-5.6, after a period during which access to the model was limited for national security reasons.

The decision comes in the context of the technological competition between the U.S. and China and concerns regarding the use of highly advanced AI models in sensitive areas, such as cybersecurity, according to Hotnews.

The new GPT-5.6 family includes three variants: Sol, the most powerful model, Terra, a balanced version for everyday use, and Luna, optimized for cost and speed.
