## [Safetensors: The Secure, Scalable Format Powering LLM Inference](https://docs.rafay.co/blog/2025/04/23/safetensors-the-secure-scalable-format-powering-llm-inference/)

As Large Language Models (LLMs) like LLaMA, Mistral, and DeepSeek continue to scale into the hundreds of billions of parameters, model efficiency becomes as important as model quality.

One often-overlooked bottleneck is the **model loading format**. This is one of the primary focus areas for [**safetensors**](https://huggingface.co/docs/safetensors/en/index).
