OpenAI gets green light for GPT-5.6 – rolling out Sol, Terra and Luna
After clearing a US safety review, OpenAI is rolling out the new GPT-5.6 model series on 9 July 2026. The series includes the flagship Sol, alongside the Terra and Luna variants.

What happened?
OpenAI has received the green light from the US government to begin a wider rollout of its new GPT-5.6 model series on 9 July 2026. The series consists of three variants: the flagship model Sol, the balanced everyday variant Terra, and the fast, cost-effective Luna. The release was previously delayed due to an extensive US safety review.
Key facts
Why it matters
The GPT-5.6 series marks a significant step forward for OpenAI, with improved performance in source code generation, scientific calculations, cybersecurity, and direct computer control. The tiered pricing model—where Sol costs $5.00 per million input tokens while Terra costs half that—allows companies to tailor their AI usage to their specific budget and performance requirements.
Who is affected?
The rollout primarily concerns developers and businesses in the US market using OpenAI’s API for programming, research, and cybersecurity applications. Global users and EU-based developers must wait for further announcements regarding local availability.
Impact on the EU
The models are being released initially in the US after passing a US safety review. At present, there is uncertainty regarding the exact timeline for availability within the EU and how the models will be adapted to meet the requirements of the EU AI Act.
What else you should know
Approval from US authorities was delayed due to extended safety reviews, particularly concerning the models' advanced capabilities in cybersecurity and autonomous computer control mechanisms.
