This page explains how Devin’s work is metered. The mechanics are the same regardless of pricing model. The only difference is the unit:
  • Enterprise customers consume Agent Compute Units (ACUs) against the volume in their order form.
  • Self-serve customers consume their plan’s included quota first, then draw from prepaid on-demand credits.
Throughout this page, “usage” refers to whichever unit applies to your account.

​
What counts toward usage

Usage accrues based on the work Devin actually performs in a session, including:
  • Number and complexity of actions Devin takes (planning, context gathering, task execution, browser actions, code execution, and so on)
  • Virtual machine time and networking bandwidth (typically a small fraction of total usage)
Aside from the few units required to keep the Devin VM running, Devin will not consume usage when:
  • Waiting for your response
  • Waiting for a test suite to run
  • Setting up and cloning repositories

​
Sleep and idle behavior

When a session is idle, Devin goes to sleep. While sleeping, Devin does not consume usage. You can wake the session up at any time by sending another message. Devin typically sleeps automatically after roughly 0.1 ACUs (or the equivalent quota / on-demand credit) of inactivity.

​
Managing usage effectively

A number of variables affect how much Devin consumes:
  • Task complexity
  • Prompt quality (or specificity)
  • Size of context or codebase
  • Number of files being touched or modified
  • Session runtime
  • Length of conversation
  • Frequency of back-and-forth messaging
A few tips to keep usage under control:
  • Delegate clearly scoped tasks with a well-defined end goal
  • Keep prompts and sessions short
  • Avoid asking Devin to do a lot of different tasks in the same session
  • Split big projects into sub-tasks across sessions; there are no concurrent session limits, so take advantage of it
These tips also tend to improve the quality of Devin’s work, so it’s a win-win.

​
Frequently asked questions

No, Devin does not consume any usage while sleeping.
Devin typically sleeps automatically after roughly 0.1 ACUs (or the equivalent quota / on-demand credit) of inactivity, so awake-but-idle time generally adds up to very little.
Any user can see per-session usage from Session Insights, regardless of pricing model.
  • Self-serve: Current month’s usage, quota remaining, and on-demand credit balance live at Settings > Billing.
  • Enterprise: Enterprise and per-Organization ACU consumption are available from the Consumption and Consumption Analytics pages in Enterprise and Organization Settings respectively.
