Google Magika adds 200+ file types

Google’s Magika is an open-source file content-type detector that uses a compact deep-learning model to classify files by bytes, not just extensions. The repo highlights millisecond inference on CPU, 200+ content types, and usage at Google scale across Gmail, Drive, and Safe Browsing.

// ANALYSIS

This is the kind of “AI-powered” tool that actually earns the label: it replaces brittle heuristics with content-aware classification and does it fast enough for real pipelines.

–The biggest value here is not novelty, it’s reliability; better file typing directly improves security scanning, routing, and downstream automation
–Magika’s Rust CLI plus Python, JS/TS, and Go bindings make it easy to slot into backend services, CI checks, and content pipelines
–The 200+ content-type coverage matters most for modern dev formats like notebooks, config files, and ML artifacts, where extensions are often misleading
–Google’s own production usage is the real signal: this is already battle-tested at scale, not just a demo repo
