Devin

Meet Devin, the groundbreaking AI software engineer that's changing how we think about software development. Created by Cognition AI, a startup founded by competitive programming champions, Devin represents a major leap forward in autonomous coding technology.

Unlike traditional coding assistants that just help with snippets, Devin can handle entire software projects from start to finish. It reads your instructions in plain English, creates detailed plans, writes complete applications, tests them, fixes bugs, and even deploys them to production.

With its own development environment including a code editor, terminal, and web browser, Devin works just like a human developer would, but around the clock. This innovative tool is designed to work alongside development teams, handling routine tasks so human engineers can focus on creative problem-solving and strategic work.

Devin is an autonomous AI software engineer developed by Cognition AI that can independently handle complex software development tasks. Think of it as having a junior developer on your team who never gets tired, works 24/7, and can tackle coding projects with minimal supervision.

Devin uses advanced AI models combined with long-term reasoning capabilities to understand project requirements, create detailed implementation plans, write code, run tests, debug issues, and deploy applications. The system operates within its own sandboxed computing environment, complete with a shell, code editor, and web browser, giving it all the tools a human developer would need.

What makes Devin unique is its ability to learn and adapt over time, remembering context from previous tasks and improving its performance. It achieved a 13.86% success rate on the SWE-bench coding benchmark, significantly outperforming other AI coding tools. The AI can handle everything from simple bug fixes to complex migrations involving thousands of code changes.

Getting started with Devin is straightforward and designed for team collaboration. First, sign up for an account at app.devin.ai and choose your pricing plan. Devin integrates seamlessly with Slack, making it feel like chatting with a team member. Simply tag Devin in your Slack workspace and describe what you need in plain English.

Here's how to get the best results:

• Start small: Begin with clear, specific tasks like "Fix the login bug in the user authentication module" rather than vague requests

• Provide context: Share relevant code repositories, documentation, or examples to help Devin understand your project better

• Use the web interface: For complex projects, access Devin's full IDE environment through the web application where you can monitor progress and collaborate in real-time

• Break down large tasks: Split complex projects into smaller, manageable pieces for better success rates

• Review and iterate: Monitor Devin's work, provide feedback, and make adjustments as needed

Devin works best when treated as a junior team member who needs clear direction and regular check-ins. The tool remembers conversation context, so you can build on previous work and ask follow-up questions. Always review the output before deploying to production, as Devin performs best on well-defined, smaller-scope tasks.

Devin offers a comprehensive suite of autonomous development capabilities that go far beyond traditional coding assistants. The AI operates in its own cloud-based development environment, equipped with all the tools a human developer needs.

Core capabilities include:

• Autonomous development: Devin can plan, code, test, debug, and deploy complete applications without human intervention

• Multiple AI models: Access to advanced language models including GPT-4 and Claude for different coding scenarios

• Real-time collaboration: Work alongside Devin through Slack integration or the web-based IDE interface

• Learning and adaptation: The system improves over time, learning from your codebase patterns and team preferences

• Full-stack capabilities: Handle frontend, backend, databases, APIs, and deployment across various technologies

• Code migration: Excel at large-scale refactoring and migration projects, as demonstrated with major companies like Nubank

Advanced features:

• Interactive planning: Get detailed project plans before execution begins

• Devin Search: Code search capabilities across your entire codebase

• Devin Wiki: Automated documentation generation and knowledge management

• API access: Programmatic access for enterprise workflows and automation

• Custom fine-tuning: Available for enterprise clients to specialize Devin for specific use cases

The platform supports parallel processing, allowing multiple Devin instances to work on different tasks simultaneously, making it suitable for large development teams and complex projects.

Devin offers flexible pricing to accommodate different team sizes and usage patterns. The pricing is based on Agent Compute Units (ACUs), which measure the computing resources Devin uses during active work.

Pricing plans include:

• Core Plan: Starting at $20 minimum, pay-as-you-go model at $2.25 per ACU. Perfect for individuals and small teams wanting to try Devin without monthly commitments

• Teams Plan: Includes 250 ACUs monthly at $2.00 per ACU, then additional ACUs at the standard rate. Ideal for development teams with regular coding needs

• Enterprise Plan: Custom pricing with advanced features like fine-tuning, priority support, and dedicated account management

Each ACU represents approximately 15 minutes of active Devin work. The actual consumption depends on task complexity, codebase size, and session runtime. Devin only consumes ACUs when actively working on tasks, not during idle time. All plans include unlimited seats, API access for Teams and Enterprise users, and retain full intellectual property rights for your code.
