Header + metadata + tensors. mmap-friendly.
What you're seeing
Both formats are header + tensor index + raw bytes. GGUF embeds tokenizer + hyperparams.
★ KEY TAKEAWAY
Both GGUF and SafeTensors are mmap-friendly: header + tensor index + raw bytes. The whole file maps into virtual memory; pages fault in on access.
▶ WHAT TO TRY
- Switch between formats to see the layout differences.
- GGUF embeds tokenizer + hyperparams; SafeTensors needs separate config.
