Devin usage resets on your monthly billing anniversary — the same date each month that you originally subscribed. Usage is measured in ACUs (Agent Compute Units), not messages or tokens, and your ACU allowance refreshes at the start of each new billing cycle. There is no daily reset; it's purely monthly.
What are ACUs and how does Devin measure usage?
ACUs (Agent Compute Units) are Cognition's proprietary unit for measuring Devin's compute consumption. Each task Devin runs — spinning up a sandbox, executing code, browsing the web, running tests — consumes ACUs based on the complexity and duration of the work. A short bug fix might use 1-3 ACUs; a longer multi-step feature build can consume 10+ ACUs. Your plan's monthly ACU cap is the core usage limit you need to track.
Unlike chat-based tools like Cursor or Claude Code that count messages or tokens, Devin charges by autonomous compute effort. This makes usage harder to predict in advance, since you won't know exactly how many ACUs a task will consume until it's done.
When does Devin usage reset exactly?
Devin resets your ACU balance on your monthly billing date. If you subscribed on the 8th of a given month, your usage resets on the 8th of every subsequent month. There is no weekly or daily rollover. Once you exhaust your ACU allocation before the billing date, Devin will either pause new tasks or prompt you to purchase additional ACUs, depending on your plan settings.
To find your exact reset date, check your billing settings in the Cognition dashboard under Account or Billing. The reset timestamp is tied to UTC, so if you're in a timezone significantly ahead or behind UTC, the reset may appear to happen the evening before or morning after your local billing date.
What are Devin's plan limits and ACU allocations?
As of mid-2026, Devin offers tiered plans based on ACU volume. The Starter plan includes a fixed monthly ACU allocation suitable for light experimentation, while Team and Enterprise tiers provide higher caps and the ability to purchase ACU top-ups. Unused ACUs generally do not roll over to the next billing cycle on standard plans.
| Plan | ACU Allocation | Reset Cadence | Rollover |
|---|---|---|---|
| Starter | Limited monthly ACUs | Monthly (billing date) | No |
| Team | Higher monthly ACUs | Monthly (billing date) | No |
| Enterprise | Custom / negotiated | Monthly or custom | Negotiable |
| ACU Top-ups | Pay-as-you-go | No reset (consumed on use) | Yes (until used) |
For the most current ACU numbers per plan, check Cognition's pricing page directly, as allocations have changed with product updates.
How do you check your current Devin usage?
You can monitor ACU consumption from the Cognition dashboard at app.cognition.ai. The usage panel shows ACUs consumed in the current billing period and your remaining balance. Individual sessions also display ACU cost after completion, so you can audit which tasks are burning the most compute.
Devin doesn't currently have a native menu bar widget or desktop monitor. If you work heavily with multiple AI coding tools and want a system-level view of usage across them, tools like Usagebar track Claude Code's 5-hour window and weekly caps directly in your macOS menu bar — useful if Devin is part of a broader AI dev stack.
What happens when Devin runs out of ACUs?
When your ACU balance hits zero mid-cycle, Devin stops accepting new autonomous tasks until you either purchase an ACU top-up or wait for the monthly reset. In-progress tasks at the time of depletion may pause or fail depending on the task state. You'll receive email notifications as you approach your limit — typically at usage thresholds like 80% and 100%.
If you're on a Team plan with multiple seats, ACU consumption is pooled across the team by default, meaning one heavy user can exhaust the budget for the whole group before month-end.
Does Devin have a free tier with usage limits?
Devin has historically offered trial or limited-free access during early availability periods, but as of 2026, it is primarily a paid product. Any free trial ACUs are one-time grants and do not reset monthly. Once a trial allocation is consumed, you need an active paid plan to continue using Devin.
How does Devin's reset cycle compare to other AI coding tools?
Most AI coding tools reset on different cadences, which matters when planning your workflow across multiple tools.
| Tool | Usage Unit | Reset Cadence |
|---|---|---|
| Devin | ACUs | Monthly (billing date) |
| Claude Code (Pro) | Messages / tokens | Every 5 hours + weekly cap |
| Cursor | Fast requests | Monthly (billing date) |
| OpenAI Codex | API tokens | Monthly (billing date) |
| GitHub Copilot | Completions / chat turns | Monthly (billing date) |
Claude Code is notably different because it uses a rolling 5-hour window rather than a clean monthly reset. If you use Claude Code alongside Devin, see when does Claude Code usage reset for details on how that window works.
For Codex billing cycles, Codex usage limit and reset time has a comparable breakdown. If you're deciding between the two for autonomous work, the Claude Code vs Devin comparison covers how their usage models affect day-to-day costs.
Tips for managing your Devin ACU budget
- Scope tasks tightly before sending to Devin. Vague instructions cause Devin to explore more paths, consuming extra ACUs. Clear specs reduce waste.
- Use the ACU estimate before confirming. Cognition's UI often shows a projected ACU cost before Devin starts. Review it and abort if it seems high for the task complexity.
- Audit completed sessions. The dashboard logs ACUs per session. Review weekly to spot expensive task types and handle those manually or with cheaper tools.
- Set team spending alerts. On Team plans, configure budget alerts so no single user drains the shared pool unexpectedly.
- Reserve ACUs for end-of-month. If your cycle ends on the 28th-31st and you've burned 90% of ACUs by the 20th, hold remaining credit for urgent tasks rather than running exploratory work.
Key takeaways
- Devin usage resets monthly on your billing anniversary date, not daily or weekly.
- Usage is measured in ACUs — compute units tied to task complexity, not message count.
- Unused ACUs generally do not roll over on standard plans.
- ACU top-ups are available if you exhaust your allocation before reset.
- Check your exact reset date and remaining balance in the Cognition dashboard.
- If you run Claude Code alongside Devin, its reset works differently — on a rolling 5-hour window.
