Devin is an autonomous AI software engineering agent from Cognition AI that independently plans, writes, tests, debugs, and ships pull requests for a given task, distinguishing it from developer-assist tools that require constant human guidance.
Cognition was founded in November 2023 by Scott Wu, Steven Hao, and Walden Yan, and launched Devin in March 2024 as what it called the 'world's first AI software engineer.' The company is headquartered in San Francisco and raised over $1 billion in May 2026 at a $26 billion post-money valuation.
Devin operates in a sandboxed development environment where it can browse documentation, write and execute code, run tests, use a shell, and manage version control autonomously across multi-step tasks.
The platform integrates via an IDE plugin and Slack, supports multiple parallel sessions, and uses a knowledge base/playbook system so teams can codify repository-specific conventions that Devin references on future tasks.
Devin is priced using Agentic Computing Units (ACUs), a normalized measure of compute and inference used per task, with roughly one ACU equal to 15 minutes of active work.
The Core plan starts at $20/month with pay-as-you-go billing at $2.25/ACU, the Team plan is $500/month with 250 included ACUs (~62.5 hours), and Enterprise offers custom, self-hosted deployment pricing.

An Agentic Computing Unit (ACU) is Devin's normalized measure of compute, model inference, and networking resources used while actively working on a task, with roughly one ACU equal to 15 minutes of active autonomous work.
Cognition AI was founded in November 2023 by Scott Wu, Steven Hao, and Walden Yan, and launched Devin in March 2024.
Enterprise customers reported to use Devin in production include Citi, Goldman Sachs, Mercedes-Benz, Dell, Santander, and branches of the US military including the Army and Navy.
Devin is designed for full task autonomy, taking a task from description through a shipped pull request, whereas Copilot and Cursor primarily assist a human engineer during active coding rather than owning tasks end to end.
