# Feature Drop: GPT-5.6 Sol, Terra, and Luna Now Available

Published on July 9th, 2026

> **Update (July 14, 2026):** The GPT-5.6 family (Sol, Terra, and Luna) is now also available hosted in the EU.

OpenAI's latest GPT-5.6 model family is now available in Omnifact. This release introduces a three-tier model architecture—Sol, Terra, and Luna—designed to deliver stronger performance per dollar and more intelligence from every token.

Building on our recent [GPT-5.5 rollout](https://omnifact.ai/blog/feature-drop-introducing-gpt-5-5), the GPT-5.6 family solves the traditional compromise between capability and cost. You can now align the exact level of intelligence needed for your specific task, from advanced reasoning to high-volume data processing.

## The GPT-5.6 Tiers

-   **GPT-5.6 Sol:** OpenAI's new premium flagship model. It establishes a new standard for complex problem solving, coding, and knowledge work, outperforming previous generations while using fewer tokens.
-   **GPT-5.6 Terra:** A balanced choice for everyday professional work. It provides capabilities competitive with previous flagship models but operates at a significantly lower cost.
-   **GPT-5.6 Luna:** Their most efficient model for high-volume workloads. It delivers fast, reliable results for everyday assistance and rapid text processing.

## Stronger Performance

The GPT-5.6 family is built to handle long-horizon tasks and coordinate tools more effectively. These models process intermediate results and adapt their workflows as they progress. This means fewer steps, less manual guidance, and a faster path to ready-to-use results for your team.

For tasks that require heavy analysis, the new models provide a step change in design judgment, rendering, and logic, catching issues and applying finishing touches before handing the work back.
