OpenAI Launches GPT-5.6 Broadly After US Government Approval
OpenAI has made GPT-5.6 broadly available after the U.S. government approved a wide release. The model family consists of three tiers: Sol, Terra, and Luna. According to Artificial Analysis benchmarks, the top tier Sol scores 59 points on the Intelligence Index, one point behind Anthropic's Claude Fable 5, while costing roughly $1.04 per task compared to Fable 5's $2.75. Sol also leads the Coding Agent Index. GPT-5.6 introduces cache-write pricing for the first time. Before the public launch, the model was available to about 20 government-approved partners following a voluntary pre-release review led by the Commerce Department - a precedent OpenAI views with unease. Overall, the release positions OpenAI at near-frontier performance for significantly lower cost, while the approval process may set the template for future U.S. frontier model launches.
First U.S. frontier model to require formal government pre-release approval; near-frontier performance at roughly 60% lower cost could reshape AI economics and set a regulatory precedent for future model releases.
