Execution Modes

Every agent run uses one of three execution modes: Auto, Fast, or Deep.

Auto mode

Auto (default for Internal agents) lets Auteryn’s SmartRouter classify each incoming task and pick Fast or Deep automatically. Use Auto when you want the platform to balance speed and depth without manual tuning.

Fast mode

Fast is optimized for speed. It’s ideal for:

Short Q&A conversations
Simple lookups and retrievals
Quick summaries
Customer-facing chat where response time matters
High-volume interactions

Responses are typically returned in a few seconds. Fast mode uses fewer credits per run.

Deep mode

Deep is optimized for depth and accuracy. It’s ideal for:

Complex, multi-step tasks (“write a full test suite for this module”)
Long-form research and synthesis
Tasks that require planning and multiple integration calls
Code generation, debugging, architecture review
Anything where quality matters more than speed

The agent spends more time reasoning before and during the task. Deep mode uses more credits but produces significantly better results for complex work.

How mode is selected

Scenario	Mode used
Agent type is Customer-Facing	Always Fast
Agent type is Internal + Auto enabled	SmartRouter picks Fast or Deep per task
You set Fast or Deep in agent settings	The default every message starts on
You pick Auto, Fast or Deep on the pill in the message box	That message only

For Internal agents, set the default in Agent → Settings → Execution Mode, and change it for a single message with the Auto / Fast / Deep pill next to the send button. The pill starts on the agent’s default.

When to override

I want…	Use
Fast, snappy responses for end users	Fast
The best possible answer for a hard problem	Deep
Lower costs on a high-traffic agent	Fast (or set a credit limit)
A coding assistant that writes production-quality code	Deep
Let the platform decide per task	Auto
