OpenAI Announces, But Is Blocked From Releasing, New GPT-5.6 Models

OpenAI yesterday:

We’re beginning a limited preview of the GPT‑5.6 series: Sol, our flagship model; Terra, a balanced model for everyday work; and Luna, a fast and affordable model. Terra has competitive performance to GPT‑5.5 while being 2× cheaper and Luna brings strong capability at our lowest cost.

GPT‑5.6 Sol launches with our most robust safety stack to date. We strengthened protections for higher-risk activity, sensitive cyber requests, and repeated misuse, and spent multiple weeks finding weaknesses, pressure-testing our system, and hardening it against real-world attacks.

We believe in broad access, and we plan to make GPT‑5.6 Sol, Terra, and Luna generally available in the coming weeks. As part of our ongoing engagement with the U.S. government, we previewed our plans and the models’ capabilities ahead of today’s launch. At their request, we are starting with a limited preview for a small group of trusted partners whose participation has been shared with the government, before releasing more broadly.

Stephanie Palazzolo, reporting for The Information (and posted to X) regarding an internal Q&A hosted by CEO Sam Altman:

The reason for the staggered release, Altman explained: The federal government asked it to do so. Altman said that this was the best path for widely releasing the model as soon as possible, said one of the people. In a Thursday memo, Altman told staff that the government would be “approving access customer by customer during this preview period” for GPT 5.6. He added that he hoped there would be a more general release a “couple of weeks later” if all went well. [...]

Even so, after OpenAI had shared its plans for the limited release with top government officials earlier this week, Altman still received a call from Commerce Secretary Howard Lutnick cautioning the company against launching without receiving approvals from other agencies, according to a person familiar with the call.

It is perfectly reasonable to believe that the U.S. government should have regulatory approval over frontier AI models. It’s absurd to think this should be run by an apparatchik with zero AI expertise like Commerce Secretary Howard Lutnick.

AI regulation should be thoughtful, measured, consistent, objective, and deeply informed. It should not be impulsive, impetuous, petty, uninformed, subjective, inconsistent, and transactional. The latter, however, is what we’re getting.
