Magika is Google's AI-powered file content-type detection library, now available as open source. Unlike traditional magic-byte heuristics (like libmagic), Magika uses a small custom deep learning model that runs in milliseconds on CPU and identifies 200+ file types with approximately 99% accuracy — a significant improvement over rule-based alternatives, especially on binary formats and polyglot files. Available as a CLI (Rust), Python package, and JavaScript/TypeScript library, Magika integrates cleanly into build pipelines, security scanners, and file-processing backends. Google deploys it internally to route hundreds of billions of files per week across Gmail, Drive, and Safe Browsing. It's also integrated with VirusTotal and abuse.ch for malware triage. A research paper was published at ICSE 2025. The practical use cases are broad: malware analysis, upload validation, content pipelines, archival systems, and anywhere you need to trust a file's actual type rather than its extension. The model footprint is small enough to ship with a CLI or embed in a serverless function — no GPU required.
Reviewer scorecard
“Perfect for prototyping. I described a dashboard and had a working app in 3 minutes. Not production-ready, but unbeatable for speed-to-demo.”
“Drop-in replacement for libmagic with dramatically better accuracy on edge cases — and since Google uses this on billions of files per week, I trust the production validation more than most OSS libraries. The JS/TS package makes it easy to add file validation to web APIs without a sidecar process.”
“Impressive demo, but the generated code is messy and you'll rewrite most of it. If you can't code, you can't fix what it breaks. Know what you're getting into.”
“Most developers don't need 99% accuracy on file detection — libmagic or a simple extension check handles 95% of real-world cases just fine. And adding an ML model to your file processing pipeline is complexity that most projects don't need to take on.”
“As a creator who needs quick landing pages and MVPs, this is a game-changer. I built a waitlist page with email capture in under 5 minutes.”
“As a creator, I rarely need to detect file types programmatically — my tools handle that. This is genuinely impressive engineering but it's squarely a developer and security-team tool, not something that changes my creative workflow.”
“As AI-generated files become harder to classify by structure alone — synthetic audio, AI-written code, hybrid media formats — learned file detection becomes a security primitive. Magika is the right architecture for a future where file types are increasingly adversarially crafted.”
