About GGUF Inspector
What is GGUF Inspector?
GGUF Inspector is a free, browser-based tool for analyzing GGUF model files used by llama.cpp, Ollama, and other local LLM frameworks.
With GGUF Inspector, you can:
- View model metadata (name, architecture, context length, etc.)
- Inspect tensor layout and dimensions
- Analyze quantization distribution
- Estimate parameter counts
- Explore model architecture hierarchy
How It Works
GGUF Inspector is 100% client-side. Your files never leave your device.
The tool uses the File.slice() API to read only the header and metadata sections of your GGUF file (typically the first 10-30 MB), without loading the entire file into memory. This means you can inspect even 100GB+ models instantly.
All processing happens in your browser using vanilla JavaScript and the Web File API. No servers, no uploads, no privacy concerns.
