OpenAI to Roll Out Top AI Model Globally After Limited Preview — Government Limits Lifted

What happened

OpenAI on July 8 confirmed that GPT-5.6 Sol — the flagship model in the GPT-5.6 family — will be globally available from Thursday July 10, 2026, after US government restrictions were lifted.

Context and impact

GPT-5.6 Sol was halted after its late-June preview under pressure from Washington, which demanded security vetting before wide release. Sam Altman announced the unblock with 'Happy building.' The GPT-5.6 family covers three pricing tiers.

Details

• Sol: flagship — coding, biology, cybersecurity
• Terra: mid-range, ~50% of GPT-5.5 price
• Luna: lightweight, budget-friendly
• Limited preview ran since late June with vetted partners
• Global release from July 10 with no geographic restrictions
