If you’ve ever thought about merging different pre-trained language models to create a customized powerhouse of AI, you’re in the right place! This guide will walk you through the steps using a project known as Stellar Odyssey 12b. So, buckle up and get ready for this stellar journey!

Understanding the Basics

Merging language models can be compared to blending different flavors of ice cream. Each flavor brings its unique taste, and when combined, they can create something deliciously unique. In our case, you’ll be blending different models to harness their strengths.

Prerequisites

• Python installed on your machine
• Access to MergeKit (https://github.com/cg123/mergekit)
• Basic understanding of YAML (Yet Another Markup Language)

Step-by-Step Guide to Merging Models

1. Setting Up Your Environment

First, ensure that you have MergeKit installed and ready to go. Download the necessary models that you wish to merge. For our Stellar Odyssey, we are using:

• Mistral-Nemo-Base-2407
• Sao10K_MN-12B-Lyra-v4
• Gryphe_Pantheon-RP-1.5-12b-Nemo
• nothingiisreal_MN-12B-Starcannon-v2

2. Merging the Models

Next, navigate to your command line interface and input the commands to merge the models. We’ll be using the della_linear merge method:

mergekit merge \
    --base_model /path/to/Mistral-Nemo-Base-2407 \
    --models /path/to/Sao10K_MN-12B-Lyra-v4 \
             /path/to/nothingiisreal_MN-12B-Starcannon-v2 \
             /path/to/Gryphe_Pantheon-RP-1.5-12b-Nemo \
    --config /path/to/config.yaml

3. Configuring Your Merge

To tailor the merging process, you’ll need a YAML configuration file. Here’s an example based on our Stellar Odyssey:

models:
  - model: /path/to/Sao10K_MN-12B-Lyra-v4
    parameters:
      weight: 0.3
      density: 0.25
  - model: /path/to/nothingiisreal_MN-12B-Starcannon-v2
    parameters:
      weight: 0.1
      density: 0.4
  - model: /path/to/Gryphe_Pantheon-RP-1.5-12b-Nemo
    parameters:
      weight: 0.4
      density: 0.5
merge_method: della_linear
base_model: /path/to/Mistral-Nemo-Base-2407
parameters:
  epsilon: 0.05
  lambda: 1
dtype: bfloat16

Troubleshooting Common Issues

While merging can be exciting, it does come with its share of hiccups. Here are some potential issues you might encounter and how to solve them:

• Problem: Mergekit fails to find the model files.
  Solution: Ensure that the paths to the model files in your configuration are correct.
• Problem: Memory errors during the merge process.
  Solution: Try decreasing the size of the models or increasing the memory allocation for your process.
• Problem: Unexpected output from the merged model.
  Solution: Revisit your YAML configuration to make sure the weights and densities reflect your desired output.
