Muse connects GPT-5.6 models to your personal AI assistant, so GPT-5.6 Sol, GPT-5.6 Terra, and GPT-5.6 Luna can help turn connected context into research, slides, reports, documents, and real work outcomes—with your permission.
Sol, Terra, and Luna give Muse a flexible model family for deep reasoning, balanced everyday work, and fast high-volume execution.
GPT-5.6 Sol is positioned as the flagship model in the family, designed for complex coding, knowledge work, research, cybersecurity, science, computer use, and design judgment. In Muse, it is best used when a task needs deeper reasoning and careful output quality.
GPT-5.6 Terra is described as a balanced model for everyday work, offering a practical mix of capability, speed, and cost. In Muse, Terra can support recurring work such as meeting briefs, document drafts, file summaries, and project updates.
GPT-5.6 Luna is described as the fastest and lowest-cost model in the GPT-5.6 family. In Muse, Luna is useful for lighter, high-volume tasks such as summarization, extraction, triage, and repeated workflow steps.
Muse is not just a place to chat with a model. It connects model capability with your chosen context, your preferences, and Muse skills for creating slides, reports, documents, websites, images, research briefs, and structured files.
Muse can route tasks conceptually across Sol, Terra, and Luna depending on depth, speed, and workflow needs.
Use Sol when the work is complex, multi-step, or quality-sensitive: research synthesis, product strategy, software planning, analytical reports, design review, and complex document generation.
Best for
Use Terra when the task needs reliable reasoning but should still feel fast and practical: meeting prep, file summaries, weekly updates, email drafts, and operational planning.
Best for
Use Luna when speed and scale matter: extracting action items, summarizing long threads, cleaning structured notes, classifying feedback, and preparing first-pass drafts.

Use this as a practical guide for choosing the right GPT-5.6 tier inside Muse workflows.
| GPT-5.6 Sol | GPT-5.6 Terra | GPT-5.6 Luna | Best used in Muse for | |
|---|---|---|---|---|
| Primary role | Flagship model for the most demanding work | Balanced model for everyday work | Fast model for scalable tasks | Match the model tier to the complexity and urgency of the deliverable. |
| Reasoning depth | Best fit for deep reasoning, coding, research, and complex analysis | Balanced capability and efficiency | Prioritizes speed and cost | Use Sol for strategy, technical planning, and high-stakes reports; Terra or Luna for recurring workflows. |
| Knowledge work outputs | Strong fit for polished documents, presentations, spreadsheets, and interface review | Everyday knowledge work | Lighter repeated outputs | Create decks, reports, briefs, summaries, and structured documents from connected context. |
| Cost and speed orientation | Highest-capability tier | Balanced tier | Fastest and lowest-cost tier | Use Luna for high-volume summarization or extraction, Terra for daily work, and Sol for complex deliverables. |
Model availability, routing, and performance may depend on Muse product implementation, user plan, and connected context. This table is a practical workflow guide, not benchmark or pricing advice.
Choose a personal AI assistant, connect the tools you want Muse to use, and turn GPT-5.6 capability into research, slides, reports, documents, and real workflow outcomes.
