OpenAI released GPT-5.6 Sol, Terra, and Luna models broadly on Thursday following initial limited deployment. CEO Sam Altman told CNBC the Sol model achieves 54% greater token efficiency on agentic coding tasks compared to previous versions.

OpenAI will release its GPT-5.6 model family on July 9, 2026, following a delay for U.S. government review. The release includes three capability tiers: Sol (flagship), Terra (balanced), and Luna (fast and affordable).

OpenAI will publicly release its GPT-5.6 Sol, Terra and Luna models on Thursday, two weeks after restricting access to select partners at U.S. government request. The release follows Anthropic's restoration of its Claude Fable 5 and Mythos 5 models after a similar government review process.

OpenAI is releasing GPT-5.6 to the public on July 9 following government security review under a Trump administration AI cybersecurity order. The release includes three variants: Sol (strongest), Terra (GPT-5.5 performance at half the cost), and Luna (lowest cost option).

The Trump administration is close to allowing Anthropic to restore access to its Fable 5 model, which has been offline for 15 days due to national security concerns. Insiders expect restrictions could be lifted as soon as next week, though Pentagon and NSA approval is still required.

OpenAI released its GPT-5.6 model lineup to a limited group of "trusted partners" after the U.S. government requested restrictions on the rollout. The company released three models—Sol ($5/$30 per million tokens), Terra ($2.50/$15), and Luna ($1/$6)—but said the government-mandated preview "shouldn't become the long-term default."

OpenAI released GPT-5.6, a three-model suite consisting of Sol (flagship), Terra (medium-tier), and Luna (fast/affordable). Sol is priced at $5 input/$30 output per million tokens—nearly half the cost of Anthropic's Claude Fable 5. The release follows Trump administration involvement in approval process.
