OpenAI has introduced GPT-5.6, a new family of three artificial intelligence models that will initially be available to a limited group of trusted partners before a wider release.
The family includes Sol, OpenAI’s new flagship model, Terra, a lower cost alternative, and Luna, its fastest and most cost efficient option.
OpenAI said it discussed the models and their capabilities with the US government before the launch. At the government’s request, the company is beginning with a restricted preview involving partners whose participation has been disclosed to officials.
The company plans to make all three models generally available in the coming weeks. It did not disclose pricing, API access details or an exact public release date.
OpenAI classified Sol, Terra and Luna as high capability in both cybersecurity and biological and chemical risk under its Preparedness Framework. None of the models reached the high capability threshold for AI self improvement.
