Models are inspected as read-only structures; inference, scripts, and custom operators are not executed.

How to use SafeTensors Viewer

SafeTensors avoids pickle code execution, but weight names alone do not prove architecture, licensing, or load compatibility.

  1. Choose a .safetensors file.
  2. Read header length and validate tensor data_offsets.
  3. Search names and inspect dtype, shape, element count, and expected bytes.
  4. Review metadata and separately verify config/tokenizer files.

What this tool helps with

  • No pickle or model-code execution
  • Quick weight-key and dimension checks
  • Processing runs in this browser tab; the file is not uploaded to FreeTool to perform the task.

Compatibility and limitations

  • No complete architecture inference or config generation
  • No inference, LoRA merge, or weight conversion
  • Large tensors are not fully expanded into a table

Frequently asked questions

Is it safer than .pt?

SafeTensors has no arbitrary-code mechanism, but file provenance and model content still matter.

Can it identify the model?

Metadata and key names provide clues but are not reliable architecture identification.

Are weights uploaded?
