Plans, usage, and what an ACU actually is

Agent pricing is harder to reason about than seat pricing, because you are buying work rather than access. Here is what Cognition publishes — and, just as usefully, what it does not.

Self-serve plans

Re-verified against Cognition’s self-serve billing docs on 29 October 2026:

Plan	List price	Members
Free	$0/month	1
Pro	$20/month	1
Max	$200/month	1
Teams	$80/month minimum	Up to 200

Pro and Max are individual plans and are documented as not shareable. On Teams, the $80/month minimum can be met by any combination of full seats and on-demand credits. A full seat is $40/month. Flex seats are free, draw from the team’s shared on-demand credits, and do not include Devin Desktop access. The 200-member cap counts both kinds of seat.

Correction, 29 October 2026: an earlier version of this guide listed Teams as having unlimited members. Cognition’s docs cap Teams at 200 members.

How usage is metered

Usage, in the docs’ words, “accrues based on the work Devin actually performs in a session.” Pro and Teams full seats have a daily and a weekly allowance. Max has a “significantly larger weekly usage quota (with no daily cap).” Go past the included usage and you keep working on prepaid on-demand credits, which the docs say never expire.

One mechanic is worth knowing because it saves money quietly: when a session goes idle, Devin goes to sleep and stops consuming usage. By default that happens after 30 minutes of inactivity; Lite sessions and API-created sessions sleep after 5 minutes. Send a message and the session wakes up. Once it goes to sleep, a session you walked away from stops using your allowance.

Enterprise

Enterprise is billed in Agent Compute Units (ACUs) at a rate set in the order form, with pricing through sales rather than a public page. Enterprise customers can also ask their Cognition account team for a different idle-sleep timeout, between 5 and 120 minutes.

What an ACU is — and what Cognition won’t say

The documented definition is about work, not time. The Enterprise billing docs say ACUs “represent the work performed by Devin for customers on the Enterprise plan,” and they are documented as distinct from self-serve quota and on-demand credits. The usage docs add that virtual machine time is “typically a small fraction of total usage.”

Now the honest part. You will find blog posts and forum answers confidently converting ACUs into minutes — commonly around 15 minutes per ACU. That number is not in Cognition’s documentation. We could not source it, so we are not going to repeat it as fact. If your budgeting depends on a time conversion, get it from Cognition in writing rather than from a secondary source.

Three other things are also not publicly documented, and we flag them rather than guessing:

• the exact quota amounts for each plan
• a per-credit price for on-demand credits (the pricing page says only that extra usage is charged at API pricing)
• any published ACU-to-wall-clock conversion

What this means if you are evaluating Devin

Because usage tracks the work Devin performs, your effective cost depends on the task and how much the agent has to do — not a flat per-seat number. Two teams on identical plans can spend very differently.

That is an argument for the scoping discipline in Writing tasks Devin can actually finish: tight, verifiable tasks are not only more reliable, they are cheaper.

Prices and mechanics change. This guide records what the sources said on 29 October 2026 — check the pricing page before making a commitment.
