The language models within AI-Public have been updated. As of today, employees and administrators have access to OpenAI’s latest GPT-5.6 generation. With the arrival of the new models GPT-5.6 Luna, GPT-5.6 Terra, and GPT-5.6 Sol, there is now a suitable level of support for every task within the public sector.
The three models are optimized for different types of work:
- GPT-5.6 Luna: The fast and cost-efficient standard for everyday office tasks. Luna is ideal for quickly writing public communications, summarizing emails, or preparing a first draft of an internal memo.
- GPT-5.6 Terra: This powerful model offers greater depth and enhanced intelligence for more complex challenges. Terra is particularly well suited to analyzing policy documents, structuring participation reports, and conducting complex text analyses.
- GPT-5.6 Sol: The most advanced flagship model is designed for demanding tasks that require in-depth reasoning, complex planning, or advanced programming assistance. For example, Sol can help review and write code for digital services or make sense of highly technical documentation.
Users can select the new models directly via the model selection menu in the chat environment. Administrators have full control over which models are available to the organization through the administrative environment. This means the flagship model GPT-5.6 Sol can be optionally enabled or disabled to help manage the budget, while employees can benefit from Luna’s speed and Terra’s analytical power by default.
With this update, AI-Public continues to support public-sector professionals with the most current, secure, and reliable technology for their daily work. Try out the new models today in your familiar working environment.
