Reasoning Engines

MIRA ships with two reasoning engines. The active engine is shown in the status bar at the bottom of the window. Switch between them in Settings → Engine (⌘,).

​

Engine comparison

Switching engines resets the active session — context from one engine is not transferred to the other.

​

Engine status

The active reasoning engine is always visible in the status bar at the bottom of the MIRA window. Switch engines any time in Settings → Engine (⌘,). Switching resets the active session.

​

Switching engines

Switching engines resets the active session — context, history, and document context from one engine are not carried over to the other. This is intentional: the two engines maintain fundamentally different internal state. To switch:

1. Open Settings (⌘,)
2. Go to the Engine tab
3. Click the engine you want to activate
4. A confirmation dialog appears if there is an active session
5. The status bar updates immediately

Your engine choice is persisted across restarts.

​

Configuration

Each engine has its own configuration panel in Settings → Engine:

• NAE Settings Reference — provider, model, context budget, multi-agent mode, MCP timeout
• RLM Settings Reference — provider, model, temperature, iteration limits, chunking strategy
