-## Customize your own model
+## Examples

-### Import from GGUF or GGML
+### Pull a public model

-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.
+```
+ollama pull llama2
+```

-1. Create a file named Modelfile, and add a `FROM` instruction with the local filepath to the model you want to import.
+> This command can also be used to update a local model. Only updated changes will be pulled.

-   ```
-   FROM ./vicuna-33b.Q4_0.gguf
-   ```
+### Run a model interactively

-3. Create the model in Ollama
+```
+ollama run llama2
+>>> hi
+Hello! How can I help you today?
+```

-   ```
-   ollama create name -f path_to_modelfile
-   ```
+For multiline input, you can wrap text with `"""`:

-5. Run the model
+```
+>>> """Hello,
+... world!
+... """
+I'm a basic program that prints the famous "Hello, world!" message to the console.
+```

-   ```
-   ollama run name
-   ```
+### Run a model non-interactively

-### Customize a prompt
+```
+$ ollama run llama2 'tell me a joke'
+ Sure! Here's a quick one:
+ Why did the scarecrow win an award? Because he was outstanding in his field!
+```

-Models from the Ollama library can be customized with a prompt. The example
+```
+$ cat <<EOF >prompts.txt
+tell me a joke about llamas
+tell me another one
+EOF
+$ ollama run llama2 <prompts.txt
+>>> tell me a joke about llamas
+ Why did the llama refuse to play hide-and-seek?
+ nobody likes to be hided!
+
+>>> tell me another one
+ Sure, here's another one:
+
+Why did the llama go to the bar?
+To have a hay-often good time!
+```
+
+### Run a model on contents of a text file
+
+```
+$ 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.

-```
-ollama rm llama2
-```
-
-### Copy a model
-
-```
-ollama cp llama2 my-llama2

-Model names follow a `model:tag` format. Some examples are `orca-mini:3b-q4_1` and `llama2:70b`. The tag is optional and, if not provided, will default to `latest`. The tag is used to identify a specific version.
