model-merging SKILL.md skillA

model-merging from orchestra-research/ai-research-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add orchestra-research/ai-research-skills/model-merging@v1.0.0

Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Merge multiple fine-tuned models using mergekit to combine capabilities without retraining. Use when creating specialized models by blending domain-specific expertise (math + coding + chat), improving performance beyond single models, or experimenting rapidly with model variants. Covers SLERP, TIES-Merging, DARE, Task Arithmetic, linear merging, and production deployment strategies.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Model Merging: Combining Pre-trained Models

## When to Use This Skill

Use Model Merging when you need to:
- **Combine capabilities** from multiple fine-tuned models without retraining
- **Create specialized models** by blending domain-specific expertise (math + coding + chat)
- **Improve performance** beyond single models (often +5-10% on benchmarks)
- **Reduce training costs** - no GPUs needed, merges run on CPU
- **Experiment rapidly** - create new model variants in minutes, not days
- **Preserve multiple skills** - merge without catastrophic forgetting

**Success Stories**: Marcoro14-7B-slerp (best on Open LLM Leaderboard 02/2024), many top HuggingFace models use merging

**Tools**: mergekit (Arcee AI), LazyMergekit, Model Soup

## Installation

```bash
# Install mergekit
git clone https://github.com/arcee-ai/mergekit.git
cd mergekit
pip install -e .

# Or via pip
pip install mergekit

# Optional: Transformer library
pip install transformers torch
```

## Quick Start

### Simple Linear Merge

```yaml
# config.yml - Merge two models with equal weights
merge_method: linear
models:
  - model: mistralai/Mistral-7B-v0.1
    parameters:
      weight: 0.5

How to install

The exact contents, by fingerprint
mdr add orchestra-research/ai-research-skills/model-merging@sha256:dfbcc6d6dfef5748

The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
