OpenAI Launches GPT-5.6 'Sol' but the U.S. Government Gates Access Customer-by-Customer — Altman Tells Staff Washington Will Approve Each One
OpenAI·high signal
OpenAI previewed GPT-5.6 'Sol' but, at the request of the Office of the National Cyber Director and OSTP, limited it to roughly 20 government-vetted partners with the administration approving access 'customer by customer during this preview period,' per Sam Altman's note to staff. The move follows the export-control order that forced Anthropic to pull Mythos and Fable, and OpenAI frames it as a path to a public rollout 'in the coming weeks' absent any federal AI-release framework. For builders, frontier-model access is now a government allowlist, not a signup form.
