# OpenAI Launches GPT-5.6 Lineup — But US Government Restricts Access to Trusted Partners Only

> OpenAI launched GPT-5.6 models Sol, Terra, and Luna but restricted access to trusted partners at the Trump administration's request, citing safety and cybersecurity review concerns.

OpenAI unveiled three new AI models under the GPT-5.6 family — Sol, Terra, and Luna — but rolled them out only to a "small group of trusted partners" at the Trump administration's explicit request. Sol is the company's most capable flagship, designed for advanced agentic tasks with state-of-the-art performance in coding, biology, and cybersecurity, priced at $5 per million input tokens. Terra is a mid-tier model for everyday use at half the cost, while Luna is a faster, lower-cost option at $1 per million input tokens.

The White House cited safety concerns and a need to assess cybersecurity implications before broad public access — a move that follows heightened scrutiny of frontier AI releases since Anthropic's Fable 5 debut. OpenAI said the restricted preview would expand to the general public in the coming weeks.

OpenAI pushed back against making such restrictions permanent: "We don't believe this kind of government access process should become the long-term default. It keeps the best tools from users, developers, enterprises, cyber defenders, and global partners who need them." The company says it is working with the administration to build a repeatable safety-assessment framework for future model releases.
