OpenAI Limits GPT-5.6 Rollout After US Government Request, Releases Three-Tier Model Suite
Tags AI · Infrastructure · Enterprise
OpenAI released GPT-5.6 as a limited preview in three versions — Sol (flagship), Terra (medium-tier), and Luna (fast/everyday) — after the Trump administration requested staggered release with government-approved customers. Priced at $5/$30 per million input/output tokens for Sol, the model excels at coding, cybersecurity, biology, and agentic tasks. Over 100 companies and agencies are authorized, including non-American employees. OpenAI stated this access process 'should not become the long-term default.'
Technical significance
This is the first time a US AI model release has been subject to government pre-approval. The tiered model (Sol/Terra/Luna) establishes a new pattern for differentiated AI deployment based on security clearance levels, which could become standard practice for frontier model releases.
