SafeView

A terminal application to view safetensors files. SafeView provides a clean, interactive terminal interface for exploring safetensors files and Hugging Face models.

Features

• Interactive terminal UI for browsing tensors
• Detailed tensor information including shape, data type, and size
• Statistical information about tensor values including min, max, mean, standard deviation, quantile analysis (1st, 10th, 25th, 50th/median, 75th, 90th, 99th percentiles), and sparsity percentage - loaded on demand when a tensor is selected
• Value distribution histogram visualization with toggle between linear and logarithmic scales
• Support for local safetensors files and Hugging Face model repositories with automatic downloading
• Real-time search and filtering by tensor name
• Clean and intuitive Textual-based interface with tabbed view (Details and Histogram)
• Optimized loading - only metadata is loaded initially, tensor statistics shown when a tensor is selected
• Progress indicators when loading tensor statistics
• Data preview snippets for quick inspection
• File-level information including total size, tensor count, and total parameter count
