Devin

03 Creation

Worth a real trial on a free account first — Cognition replaced the old $20-plus-ACU Core plan with a Free/Pro/Max ladder on July 7, so 'assign a ticket to an AI' now costs nothing to test before you commit to Pro. It shines on well-specified, bounded tasks (migrations, test coverage, dependency bumps) and still wanders on vague ones. Spec tightly, review everything.

The job in the stack

The delegated-engineering seat: an agent that takes whole tickets — bugfixes, migrations, small features — and returns pull requests.

Pricing

PlanPriceNotes
Free$0Light quota, limited model access — former Core users were migrated here
Pro$20/moFull model access (SWE 1.6, Claude, Gemini), cloud agents; overage billed in dollars past quota
Max$200/moSame feature set as Pro, significantly higher quota
Teams$80/mo + $40/seatUsage-based; former $500/mo Team plan migrated here at a lower entry point
EnterprisecustomVPC, SSO, dedicated support

Models & versions

  • Devin (Cognition)Autonomous ticket-to-PR workflow: plans, codes, tests, opens the pull request; SWE 1.6 is the current flagship model on Pro/Max

The honest read

What works

  • +Whole-ticket delegation: it returns PRs, not suggestions
  • +Excellent at grind work — migrations, coverage, upgrades — that stalls human queues
  • +Free tier now lets you evaluate before paying anything

What breaks

  • Vague tickets produce expensive wandering — specification quality is the leverage
  • Every PR still needs human review; autonomy isn't correctness
  • No more pay-as-you-go-only option — ongoing use past Free now requires a paid plan

Use it for

  • Engineering teams with backlogs of well-defined maintenance work
  • Framework migrations and dependency upgrades at scale
  • Test-coverage sprints nobody wants to staff

Skip it if

  • ×You want interactive pair-programming — Cursor and Claude Code are that
  • ×Your tickets are one-line vibes — fix the specs before hiring an agent

Questions operators ask

?Devin or Claude Code?

Claude Code works with you in the terminal — interactive, steerable, immediate. Devin works without you — assign the ticket, get a PR. Interactive depth versus asynchronous throughput; mature teams end up using the pattern, not the brand: supervised agents for hard problems, delegated agents for grind.

?What happened to Devin's ACU pricing?

Cognition dropped the $20-plus-$2.25-per-ACU Core plan and the flat $500/mo Team plan in favor of Free, Pro ($20/mo flat), Max ($200/mo), and Teams ($80/mo base plus $40/seat) — a lower, simpler entry point than the old structure.

What changed

  1. Released from staging. Cognition retired the Core/ACU plan for a Free/Pro ($20)/Max ($200)/Teams ($80+$40 per seat) ladder — corrected before release; the ACU-billed Core plan no longer exists.
  2. Added to the stack (delegated-engineering seat).
