Saving to Ollama

See our guide below for the complete process on how to save to Ollama:

🦙Tutorial: How to Finetune Llama-3 and Use In Ollama

Saving on Google Colab

You can save the finetuned model as a small 100MB file called a LoRA adapter like below. You can instead push to the Hugging Face hub as well if you want to upload your model! Remember to get a Hugging Face token via: https://huggingface.co/settings/tokens and add your token!

After saving the model, we can again use Unsloth to run the model itself! Use FastLanguageModel again to call it for inference!

Exporting to Ollama

Finally we can export our finetuned model to Ollama itself! First we have to install Ollama in the Colab notebook:

Then we export the finetuned model we have to llama.cpp's GGUF formats like below:

Reminder to convert False to True for 1 row, and not change every row to True, or else you'll be waiting for a very time! We normally suggest the first row getting set to True, so we can export the finetuned model quickly to Q8_0 format (8 bit quantization). We also allow you to export to a whole list of quantization methods as well, with a popular one being q4_k_m.

Head over to https://github.com/ggerganov/llama.cpp to learn more about GGUF. We also have some manual instructions of how to export to GGUF if you want here: https://github.com/unslothai/unsloth/wiki#manually-saving-to-gguf

You will see a long list of text like below - please wait 5 to 10 minutes!!

And finally at the very end, it'll look like below:

Then, we have to run Ollama itself in the background. We use subprocess because Colab doesn't like asynchronous calls, but normally one just runs ollama serve in the terminal / command prompt.

Automatic Modelfile creation

The trick Unsloth provides is we automatically create a Modelfile which Ollama requires! This is a just a list of settings and includes the chat template which we used for the finetune process! You can also print the Modelfile generated like below:

We then ask Ollama to create a model which is Ollama compatible, by using the Modelfile

Ollama Inference

And we can now call the model for inference if you want to do call the Ollama server itself which is running on your own local machine / in the free Colab notebook in the background. Remember you can edit the yellow underlined part.
