# Ollama
[](https://discord.gg/ollama)
Get up and running with large language models locally.
### macOS
[Download ](https://ollama.ai/download/Ollama-darwin.zip )
### Windows
Coming soon!
### Linux & WSL2
```
curl https://ollama.ai/install.sh | sh
```
[Manual install instructions ](https://github.com/jmorganca/ollama/blob/main/docs/linux.md )
### Docker
The official [Ollama Docker image ](https://hub.docker.com/r/ollama/ollama ) `ollama/ollama` is available on Docker Hub.
## Quickstart
To run and chat with [Llama 2 ](https://ollama.ai/library/llama2 ):
```
ollama run llama2
```
## Model library
Ollama supports a list of open-source models available on [ollama.ai/library ](https://ollama.ai/library 'ollama model library' )
Here are some example open-source models that can be downloaded:
| Model | Parameters | Size | Download |
| ------------------ | ---------- | ----- | ------------------------------ |
| Mistral | 7B | 4.1GB | `ollama run mistral` |
| Llama 2 | 7B | 3.8GB | `ollama run llama2` |
| Code Llama | 7B | 3.8GB | `ollama run codellama` |
| Llama 2 Uncensored | 7B | 3.8GB | `ollama run llama2-uncensored` |
| Llama 2 13B | 13B | 7.3GB | `ollama run llama2:13b` |
| Llama 2 70B | 70B | 39GB | `ollama run llama2:70b` |
| Orca Mini | 3B | 1.9GB | `ollama run orca-mini` |
| Vicuna | 7B | 3.8GB | `ollama run vicuna` |
> Note: You should have at least 8 GB of RAM to run the 3B models, 16 GB to run the 7B models, and 32 GB to run the 13B models.
## Customize your own model
### Import from GGUF
Ollama supports importing GGUF models in the Modelfile:
1. 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
```
2. Create the model in Ollama
```
ollama create example -f Modelfile
```
3. Run the model
```
ollama run example
```
### Import from PyTorch or Safetensors
See the [guide ](docs/import.md ) 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 `llama2` model:
```
ollama pull llama2
```
Create a `Modelfile` :
```
FROM llama2
# set the temperature to 1 [higher is more creative, lower is more coherent]
PARAMETER temperature 1
# set the system prompt
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 ](examples ) directory. For more information on working with a Modelfile, see the [Modelfile ](docs/modelfile.md ) documentation.
## CLI Reference
### Create a model
`ollama create` is used to create a model from a Modelfile.
### Pull a model
```
ollama pull llama2
```
> This command can also be used to update a local model. Only the diff will be pulled.
### Remove a model
```
ollama rm llama2
```
### Copy a model
```
ollama cp llama2 my-llama2
```
### Multiline input
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.
```
### Pass in prompt as arguments
```
$ ollama run llama2 "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.
```
### 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
Install `cmake` and `go` :
```
brew install cmake go
```
Then generate dependencies and build:
```
go generate ./...
go build .
```
Next, start the server:
```
./ollama serve
```
Finally, in a separate shell, run a model:
```
./ollama run llama2
```
## REST API
Ollama has a REST API for running and managing models.
For example, to generate text from a model:
```
curl http://localhost:11434/api/generate -d '{
"model": "llama2",
"prompt":"Why is the sky blue?"
}'
```
See the [API documentation ](./docs/api.md ) for all endpoints.
