OpenAI announced on June 26, 2026 that it is limiting the release of its newest GPT-5.6 model lineup to a “small group of trusted partners” following a request from the U.S. government. The company said the preview is restricted to partners “whose participation has been shared with the government,” and made clear it views the arrangement as temporary.
The GPT-5.6 lineup includes three models: Sol, the flagship; Terra, a balanced option for everyday use; and Luna, a faster, lower-cost alternative. Sol is described as OpenAI’s most capable model to date, with improved agentic capabilities in coding, biology, and cybersecurity. It introduces a “max” reasoning effort mode and an “ultra” mode that uses coordinated subagents to tackle complex tasks. Pricing runs $5 per million input tokens and $30 per million output tokens for Sol; Terra costs half that; and Luna is priced at $1 and $6, respectively.
The restrictions stem from broader U.S. government pressure on AI companies to limit access to advanced models. A recent executive order asks certain AI companies to voluntarily submit their most advanced models for government review up to 30 days before release. Dean Ball, a former White House AI adviser and incoming OpenAI employee, has argued this has created a de facto involuntary licensing regime. He warned that without clearly defined safety standards, the process could cause endless launch delays, potentially ceding ground to China in AI development and threatening billions in infrastructure investment.
The situation echoes a recent incident involving Anthropic, whose Fable 5 model was ordered pulled after the administration directed the company to remove access for any foreign nationals — prompting Anthropic to take the model down entirely.
OpenAI did not stay silent on the matter. “We don’t believe this kind of government access process should become the long-term default,” the company wrote in a Friday blog post. “It keeps the best tools from users, developers, enterprises, cyber defenders, and global partners who need them.”
OpenAI called the restricted preview a “short-term step” and said it is working with the administration on a new cybersecurity executive order framework and a “repeatable process for future model releases.” The company plans to make GPT-5.6 more broadly available through ChatGPT, Codex, and its API in the coming weeks.
