# Model Merging

Combine what several fine-tuned models know, without training again

## What this does

You have several fine-tuned models, each good at a different thing, and you want one model that does all of it. Merging combines them directly instead of running another training job. Reach for it when you want to try combinations quickly, or build a specialized model out of parts you already have.

### Top 3 things it does for you

- Blend two or more fine-tuned models into one
- Combine math, coding and chat strengths in a single model
- Try out model variants quickly

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 Model Merging

This covers merging multiple fine-tuned models with mergekit, so their capabilities combine without retraining.

It applies when you are creating specialized models by blending domain expertise such as math, coding and chat, when you want performance beyond a single model, or when you want to experiment rapidly with variants.

Several merging approaches are covered, including SLERP, TIES-Merging, DARE, task arithmetic and linear merging, along with strategies for deploying the result.

## Questions

### Is Model Merging safe to install?

AIR scanned this exact version of Model Merging and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 773a52944ba4, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/model-merging.

### How do I install Model Merging?

Open https://airmarket.ai/app/model-merging 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/773a52944ba4747a18bd4ae9ade53fff041adcbc/19-emerging-techniques/model-merging. Install from that link, not the branch.
