Are you looking to enhance the capabilities of language models like the Nemomix by combining their strengths? If so, then you’ve landed in the right place! This guide will walk you through the process of merging models using MergeKit, ensuring that your AI system operates smoothly and efficiently.

What You Need Before You Start

• Access to Hugging Face for model files.
• The MergeKit library installed.
• Basic understanding of YAML configuration files.

Understanding the Merge Concept

Imagine you are a chef looking to create the best dish possible. You have several fantastic ingredients—each with its unique flavor. By combining them in the right proportions, you can create something that is not only delicious but far superior to any single ingredient. This is essentially what merging language models is all about. You’re taking various models, each with unique training and capabilities, and combining them to produce a more versatile and effective model.

Steps to Merge Language Models

1. Collect Your Models

Your first task is to gather the pre-trained models you intend to merge. According to the data provided, you will consider the following models:

• Nemomix V1
• Nemomix V2
• Nemomix V3
• Nemomix V4 (the best choice so far!)

2. Configure Your Merge

Creating a configuration file in YAML format is essential. This file guides how models are merged, similar to how a recipe tells you the steps to prepare a dish. Here’s a sample YAML configuration for your merge:

models:
  - model: F:mergekit/invisietch_Atlantis-v0.1-12B
    parameters:
      weight: 0.16
      density: 0.4
  - model: F:mergekit/mistralai/Mistral-Nemo-Instruct-2407
    parameters:
      weight: 0.23
      density: 0.5
  - model: F:mergekit/NeverSleep/Historical_lumi-nemo-e2.0
    parameters:
      weight: 0.27
      density: 0.6
  - model: F:mergekit/intervitens_mini-magnum-12b-v1.1
    parameters:
      weight: 0.34
      density: 0.8
merge_method: della_linear
base_model: F:mergekit/mistralai/Mistral-Nemo-Base-2407
parameters:
  epsilon: 0.05
  lambda: 1
  int8_mask: true
dtype: bfloat16

3. Execute the Merge

With your configuration ready, you can run the merge command through MergeKit. This process may take some time depending on the complexity and size of the models.

Tuning Your Merge

To optimize your new model, here are some recommended settings:

• Lower the temperature to about 0.35, which will give you more focused outputs.
• If you prefer creativity, try temperatures above 1.0 (1.0-1.2).
• Ensure a Min Probability setting between 0.01 and 0.1.

Troubleshooting Tips

While merging models can be an exciting adventure, you may face a few obstacles along the way. Here are some troubleshooting ideas:

• Model Not Merging Properly: Ensure all model links are valid and that the MergeKit library is properly installed and up to date.
• Configuration Errors: Double-check your YAML configuration for syntax errors. Even a small typo can lead to significant issues!
• Performance Issues: If your new model is sluggish, consider tweaking the weights and densities in your configuration file.
