What is Magika AI?
Magika is an open-source AI-powered file type detection tool developed by Google's Security Team, released in February 2024. It uses a custom-trained deep learning model to identify file types from binary content with ~99% accuracy in under 5 milliseconds per file — far more accurate than traditional magic-byte-based tools like the Unix file command.
It's released under the Apache 2.0 license, free for any commercial use.
Why Magika Is Trending in 2026
Magika is used internally at Google for scanning billions of files in Gmail, Drive, and Safe Browsing. Its public release made enterprise-grade file type detection available to everyone — critical for malware detection, forensics, and content-management systems.
Key Features and Capabilities
Magika supports 200+ file types including PDFs, executables, archives, images, code files, and obscure formats. It runs as a Python library, command-line tool, or web service via onnxruntime for cross-platform deployment.
Who Should Use Magika?
Magika is built for security engineers, malware researchers, digital forensics teams, content moderation systems, file storage services, and DevOps engineers.
Top Use Cases
Real-world applications include malware detection (catching disguised executables), email attachment scanning, content management systems, digital forensics, file conversion pipelines, and content moderation workflows.
Where Can You Run It?
Magika runs on any system with Python (Linux, macOS, Windows), Node.js (via WASM), and even browsers. The tiny ONNX model is ~1 MB.
How to Use Magika (Quick Start)
Install: pip install magika. Use the CLI: magika suspicious_file.dat. Programmatically: from magika import Magika; m = Magika(); print(m.identify_path('file.dat').output.label).
When Should You Choose Magika?
Choose Magika whenever you need accurate, fast file-type detection, especially when content might be disguised. It's far superior to magic-byte tools for security-critical applications.
Pricing
Magika is completely free under Apache 2.0.
