## 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` |

|
|
|
|
> 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 or GGML
|
|
|
|
Ollama supports importing GGUF and GGML file formats in the Modelfile. This means if you have a model that is not in the Ollama library, you can create it, iterate on it, and upload it to the Ollama library to share with others when you are ready.
|
|
|
|
1. Create a file named Modelfile, and add 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 name -f path_to_modelfile
|
|
```
|
|
|
|
3. Run the model
|
|
|
|
```
|
|
ollama run name
|
|
```
|
|
|
|
### Customize a prompt
|
|
|
|
Models from the Ollama library can be customized with a prompt. The example
|
|
|
|
```
|
|
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
|
|
brew install 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
|
|
|
|
> See the [API documentation](docs/api.md) for all endpoints.
|
|
|
|
Ollama has an API for running and managing models. For example to generate text from a model:
|
|
|
|
```
|
|
curl -X POST http://localhost:11434/api/generate -d '{
|
|
"model": "llama2",
|
|
"prompt":"Why is the sky blue?"
|
|
}'
|
|
```
