TL;DR
OpenAI released Sol, its most powerful model, to about 20 government-approved partners under Trump's AI order.
OpenAI has released GPT-5.6 Sol, its most powerful model, to roughly 20 partners whose names were individually approved by the US government. The release is the first time an American AI company has launched a frontier model under a government-managed access list, a step beyond the voluntary pre-release review framework Trump's AI executive order established on June 2.
Sol is the most capable model in a new three-tier series that also includes Terra, a mid-range option, and Luna, which is optimized for speed and cost. OpenAI described Sol as excelling at coding, biology, and cybersecurity, and introduced a new “max reasoning effort” mode that gives the model extended time to work through complex problems. The company plans to add an “ultra” mode that splits tasks among multiple sub-agents.
The limited preview follows a direct request from the Trump administration to stagger the release, with the government approving access customer by customer during the preview period, according to Bloomberg. OpenAI said in a blog post that it does not believe “this kind of government access process should become the long-term default,” but agreed to participate.

The arrangement is the first practical test of the executive order Trump signed earlier this month, which asks AI companies to voluntarily give the government up to 30 days of pre-release access to models deemed to have advanced cyber capabilities. The order explicitly rejects mandatory licensing, but the Anthropic precedent gave it teeth. Two weeks ago, Washington ordered Anthropic to shut down Fable 5 and Mythos 5 after a reported jailbreak, the first time the government forced a commercial AI model offline.
OpenAI's decision to cooperate contrasts with Anthropic's experience. Anthropic complied with the shutdown order but publicly called the action disproportionate, warning it would halt all frontier model deployments if applied across the industry. OpenAI appears to be taking the opposite approach, framing voluntary compliance as a way to avoid a more coercive outcome while preserving its ability to push back on the principle.
Sol is also available through Amazon Bedrock, making it the first model in the new series accessible on a competing cloud platform. OpenAI said it plans to make all three tiers generally available in the coming weeks, though it has not set a public date.
The broader question is whether government-gated releases become the template for every frontier model that follows. OpenAI clearly wants to prevent that, and said so publicly. But with Anthropic's models still offline and the executive order's voluntary framework already producing mandatory-looking outcomes, the line between cooperation and compliance is getting harder to draw.
