HuggingFace Model Weight Inspector

Inspect specific parameter tensors from any HuggingFace model without downloading the entire model.

Features

• List available keys: View all parameter names in a model
• Fetch specific tensors: Download only the shard containing your parameter
• Tensor statistics: View shape, dtype, min/max/mean/std values
• Memory efficient: Uses safetensors memory-mapped loading

Usage

1. Enter a HuggingFace model ID (e.g., meta-llama/Llama-2-7b-hf)
2. Click "List Available Keys" to see all parameters
3. Enter a parameter key (e.g., model.embed_tokens.weight)
4. Click "Fetch Parameter" to view tensor info
