# Local LLM Guide with Ollama server

Ensure that you have the Ollama server up and running.
For detailed startup instructions, refer to the [here](https://github.com/ollama/ollama)

This guide assumes you've started ollama with `ollama serve`. If you're running ollama differently (e.g. inside docker), the instructions might need to be modified.

## 1. Pull Models

Ollama model names can be found [here](https://ollama.com/library). For a small example, you can use
the `codellama:7b` model. Bigger models will generally perform better.

```bash
ollama pull codellama:7b
```

you can check which models you have downloaded like this:

```bash
~$ ollama list
NAME                            ID              SIZE    MODIFIED
codellama:7b                    8fdf8f752f6e    3.8 GB  6 weeks ago
mistral:7b-instruct-v0.2-q4_K_M eb14864c7427    4.4 GB  2 weeks ago
starcoder2:latest               f67ae0f64584    1.7 GB  19 hours ago
```

## 2. Start OpenDevin

Use the instructions in [README.md](/README.md) to start OpenDevin using Docker.
But when running `docker run`, you'll need to add a few more arguments:

```bash
--add-host host.docker.internal=host-gateway \
-e LLM_API_KEY="ollama" \
-e LLM_BASE_URL="http://host.docker.internal:11434" \
```

For example:

```bash
# The directory you want OpenDevin to modify. MUST be an absolute path!
export WORKSPACE_BASE=$(pwd)/workspace

docker run \
    --add-host host.docker.internal=host-gateway \
    -e LLM_API_KEY="ollama" \
    -e LLM_BASE_URL="http://host.docker.internal:11434" \
    -e WORKSPACE_MOUNT_PATH=$WORKSPACE_BASE \
    -v $WORKSPACE_BASE:/opt/workspace_base \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -p 3000:3000 \
    ghcr.io/opendevin/opendevin:main
```

You should now be able to connect to `http://localhost:3000/`

## 3. Select your Model

In the OpenDevin UI, click on the Settings wheel in the bottom-left corner.
Then in the `Model` input, enter `ollama/codellama:7b`, or the name of the model you pulled earlier.
If it doesn’t show up in a dropdown, that’s fine, just type it in. Click Save when you’re done.

And now you're ready to go!
