OpenAI to launch GPT-5.6 model series globally on Thursday after US government clearance
OpenAI will make its GPT-5.6 model family publicly available on Thursday after the Trump administration lifted restrictions that had confined the system to a small group of vetted partners.
The announcement
OpenAI confirmed on Tuesday that its GPT-5.6 model family will be publicly available on Thursday, July 9. The company had previously restricted access to a small group of about 20 US-based partners at the request of the Trump administration. In a post on X, OpenAI said it is "expanding preview access globally now."
GPT-5.6 Sol launches Thursday! Happy building.
Three-tier model family
The GPT-5.6 series consists of three variants: Sol, the flagship model; Terra, a mid-tier option for everyday work; and Luna, a fast, low-cost alternative. Sol is described as strong in coding, biology, and cybersecurity, with a "max reasoning effort" mode for complex problems. Terra promises performance similar to the previous GPT‑5.5 at half the cost, while Luna is built for high-volume tasks where speed is paramount.

Government review and clearance
The public launch follows weeks of additional testing by the Commerce Department's Center for AI Standards and Innovation. OpenAI sent technical experts to Washington to address government questions. The review was conducted under a voluntary framework established by a June 2 executive order, but the GPT-5.6 case went further, with the government managing an access list of approved partners. OpenAI has expressed discomfort with the precedent, stating it does not believe such a process should become the long-term default, though it complied to expedite the release.
We don't believe this kind of government access process should become the long-term default.
Industry context and Anthropic
The clearance mirrors a similar path for rival Anthropic, which last week began restoring global access to its most advanced models, Fable 5 and Mythos 5, after Washington lifted restrictions. Those models had been blocked for foreign nationals under a White House directive. The back-and-forth reflects the Trump administration's evolving stance on AI regulation, balancing competitiveness with national security concerns over software vulnerability detection.
