# bitsandbytes - LLM Quantization

Fit a bigger model onto the card you already have

## What this does

The model you want will not fit in your GPU memory. This shrinks it to 8-bit or 4-bit so it does fit, with little cost to accuracy, and works with HuggingFace Transformers. It also covers QLoRA training and 8-bit optimizers. Reach for it when memory is the thing stopping you.

### Top 3 things it does for you

- Shrink a model to 8-bit or 4-bit
- Fit a larger model into limited GPU memory
- Run QLoRA training on a quantized model

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About bitsandbytes - LLM Quantization

This quantizes LLMs to 8-bit or 4-bit, cutting memory use substantially while keeping accuracy loss minimal. It supports INT8, NF4 and FP4 formats and works with HuggingFace Transformers.

Beyond inference it covers QLoRA training and 8-bit optimizers, so the same memory savings apply while you are fine-tuning.

Use it when GPU memory is limited, when you want to fit a larger model than you otherwise could, or when you are after faster inference.

## Questions

### Is bitsandbytes - LLM Quantization safe to install?

AIR scanned this exact version of bitsandbytes - LLM Quantization and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 28f2d29236f2, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/quantizing-models-bitsandbytes.

### How do I install bitsandbytes - LLM Quantization?

Open https://airmarket.ai/app/quantizing-models-bitsandbytes on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/orchestra-research/ai-research-skills/tree/28f2d29236f2bade2eb92cadb2585189589a5828/10-optimization/bitsandbytes. Install from that link, not the branch.
