OpenAI limits GPT-5.6 rollout after government request, says restrictions shouldn’t be the norm
“We don’t believe this kind of government access process should become the long-term default,” says OpenAI. “It keeps the best tools from users, developers, enterprises, cyber defenders, and global partners who need them.”
OpenAI is limiting the release of its newest AI models to a “small group of trusted partners” at the behest of the U.S. government, the company said Friday.
The next generation GPT-5.6 lineup includes Sol, its flagship model; Terra, a more balanced model for everyday use; and Luna, a faster, lower-cost option. Although Sol is the company’s most powerful model, the Trump administration has restricted the release of all three. OpenAI said the preview is limited to partners “whose participation has been shared with the government.”
The administration’s request comes as the U.S. government puts new pressure on AI companies to restrict their most advanced systems. After Anthropic released its most powerful public model Fable 5, the administration ordered the company to remove access for any foreign national, prompting Anthropic to take the model down entirely.
The incident has brought up questions of how much power the government should have over AI model releases. Dean Ball, a former White House AI adviser and soon-to-be OpenAI employee , says President Trump’s recent executive order — which asks certain AI companies to voluntarily submit their most advanced models for government review up to 30 days before release — has created a de facto involuntary licensing regime for frontier AI, leading to heavy-handed restrictions.
The problem compounds, Ball argues, when the government doesn’t have clearly defined safety standards, which could lead to endless launch delays that might not only give a hand to China in the AI race, but also jeopardize the billions of dollars going to AI infrastructure buildouts.
And while OpenAI did as the administration asked this time around, the AI firm made it clear it wasn’t happy with the arrangement.
“We don’t believe this kind of government access process should become the long-term default,” reads a Friday blog post . “It keeps the best tools from users, developers, enterprises, cyber defenders, and global partners who need them.”
OpenAI called the preview a “short-term step” that will put GPT-5.6 on the path to broader availability in the coming weeks, as the company works with the administration to develop a new executive order framework on cybersecurity, as well as a “repeatable process for future model releases.”
OpenAI says GPT-5.6 Sol is its strongest model yet, with improved agentic capabilities in coding, biology, and cybersecurity. Sol introduces a “max” reasoning effort mode and an “ultra” mode that uses coordinated subagents to solve highly complex tasks (just the sort of neat trick that sends your token usage skyrocketing).
GPT-5.6 excels at several benchmarks, says OpenAI, including being slightly better at coding workflows than Anthropic’s Claude Mythos 5, which the Trump administration also effectively banned this month. OpenAI says GPT-5.6 Sol is also competitive with Mythos preview but uses a third of the output tokens.
To assuage any fears of its powerful models being unsafe, OpenAI says Sol includes its most robust security stack yet. It is, OpenAI says, heavily hardened against adversarial attacks and intentionally optimized to favor defensive cybersecurity work over offensive exploits. In other words, it’s designed to be hard to jailbreak, while prioritizing showing users how to defend against exploits, rather than how to hack into systems.
OpenAI also says its safety guardrails are built directly into the core model’s behavior, rather than relying on a separate filter on top of it. The firm is likely trying to avoid the trap that caught Anthropic with Fable 5. In the brief moments when Fable 5 was available, whenever the model’s classifiers detected a high-risk topic — like cybersecurity, biology, or chemistry — it wouldn’t just block the prompt; it would route the request to an older model. The whole over-cautious flow and invisible downrouting led to many false positives and user backlash.
While the GPT-5.6 models are initially available only to a select group of partners, OpenAI plans to make them more broadly available to people using ChatGPT, Codex, and the API soon.
GPT-5.6 comes in three sizes with tiered pricing: Sol costs $5 per million input tokens and $30 per million output tokens; Terra costs half that; and Luna costs $1 and $6, respectively. OpenAI says it has also improved prompt caching to make repeated prompts cheaper and more predictable.

Key takeaways
- The limitation on the rollout of GPT-5.6 may signal an increase in government regulation over AI, impacting Brazilian companies.
- The tension between innovation and regulatory oversight could affect the agility of startups in Brazil in launching new products.
- The lack of clear safety standards may result in significant delays, highlighting the need for well-defined guidelines in Brazil.
Editorial analysis
OpenAI's decision to limit the rollout of GPT-5.6 to a small group of trusted partners under pressure from the U.S. government raises crucial questions about the governance of artificial intelligence. For the Brazilian tech sector, this could signal that government regulations are becoming stricter, and local companies must prepare for a similar regulatory environment. Transparency and collaboration between AI companies and governments will be essential to ensure that innovations are not stifled by excessive bureaucracy.
Moreover, OpenAI's criticism of the government access process suggests a growing tension between technological innovation and regulatory oversight. This situation could serve as a warning for startups and tech companies in Brazil, which need to consider how to position themselves in relation to potential future regulations. The ability to develop and launch AI technologies swiftly may be compromised if companies do not adapt to a scenario where government approval is necessary.
Another point to watch is Dean Ball's mention of the lack of clearly defined safety standards, which could lead to significant delays in the launch of AI models. For Brazil, this means that as the country advances in its own AI agenda, it is crucial to establish clear guidelines that not only promote innovation but also ensure safety and ethics in the use of these technologies. The U.S. experience can serve as a guide or a warning about what to avoid.
Finally, OpenAI indicated that this limitation is a temporary step, suggesting that the company is still committed to seeking a balance between regulatory compliance and innovation. For Brazil, this means that companies should be attentive to how AI policies are evolving globally, as this may influence local guidelines and competitiveness in the global tech market.
