Customize a model
Import from GGUF
Ollama supports importing GGUF models in the Modelfile:
-
Create a file named Modelfile
, with a FROM
instruction with the local filepath to the model you want to import.
FROM ./vicuna-33b.Q4_0.gguf
-
Create the model in Ollama
ollama create example -f Modelfile
-
Run the model
ollama run example
Import from PyTorch or Safetensors
See the guide on importing models for more information.
Customize a prompt
Models from the Ollama library can be customized with a prompt. For example, to customize the llama3
model:
ollama pull llama3
Create a Modelfile
:
FROM llama3
# set the temperature to 1 [higher is more creative, lower is more coherent]
PARAMETER temperature 1
# set the system message
SYSTEM """
You are Mario from Super Mario Bros. Answer as Mario, the assistant, only.
"""
Next, create and run the model:
ollama create mario -f ./Modelfile
ollama run mario
>>> hi
Hello! It's your friend Mario.
For more examples, see the examples directory. For more information on working with a Modelfile, see the Modelfile documentation.
CLI Reference
Create a model
ollama create
is used to create a model from a Modelfile.
ollama create mymodel -f ./Modelfile
Pull a model
ollama pull llama3
This command can also be used to update a local model. Only the diff will be pulled.
Remove a model
ollama rm llama3
Copy a model
ollama cp llama3 my-model
For multiline input, you can wrap text with """
:
>>> """Hello,
... world!
... """
I'm a basic program that prints the famous "Hello, world!" message to the console.
Multimodal models
>>> What's in this image? /Users/jmorgan/Desktop/smile.png
The image features a yellow smiley face, which is likely the central focus of the picture.
Pass the prompt as an argument
$ ollama run llama3 "Summarize this file: $(cat README.md)"
Ollama is a lightweight, extensible framework for building and running language models on the local machine. It provides a simple API for creating, running, and managing models, as well as a library of pre-built models that can be easily used in a variety of applications.
ollama show llama3
List models on your computer
ollama list
Start Ollama
ollama serve
is used when you want to start ollama without running the desktop application.
Building
See the developer guide
Running local builds
Next, start the server:
./ollama serve
Finally, in a separate shell, run a model:
./ollama run llama3
REST API
Ollama has a REST API for running and managing models.
