Frequently Asked Questions

Sdk vs Cognition AI: which should you choose?

Choose Cognition AI if you're an enterprise team needing an autonomous software engineer to handle bug triage, legacy modernization, and end-to-end production coding with a financial guarantee. Choose Sdk if you're a developer building automated video generation pipelines with multiple AI models and want a free, open-source, declarative API. They solve completely different problems—pick based on whether you need code engineering or video creation.

What does Cognition AI's productivity guarantee cover?

Cognition offers up to $10M AI Productivity Guarantee, meaning they will compensate enterprises if Devin doesn't deliver measurable productivity gains as agreed.

Is Sdk truly free?

Yes, Sdk is open-source under Apache 2.0 and free to use, but you need to provide your own API keys for the AI providers (e.g., ElevenLabs, fal.ai) which have their own costs.

Can Devin run on Windows?

Yes, Devin supports native Windows VM for building and testing, as well as Android emulator integration, making it suitable for cross-platform development.

Does Sdk require React?

No, though it uses React-like JSX syntax, it does not require React as a dependency. It runs on Node.js/Bun with a server-side renderer.

What integrations does Cognition AI support?

Devin integrates with GitHub, Slack, Windsurf IDE, Android Emulator, Windows VM, VS Code, Jira, Linear, and Datadog.

What AI models does Sdk support?

Sdk supports fal.ai, ElevenLabs, OpenAI, Replicate, Higgsfield, Kling, Flux, and Veed for video, image, voice, music, and lipsync generation.

Is Cognition AI suitable for small teams?

Devin is designed for enterprise engineering teams with large production codebases and may be overkill for small projects or individual developers due to its enterprise pricing and complexity.

Can Sdk be used for real-time video?

No, Sdk is not optimized for real-time or low-latency applications; it's designed for batch or pipeline-based video generation with server-side FFmpeg rendering.
