# Requirements
I\'ve recently started playing with large language models (LLMs), mostly
in the popular chatbot form, as part of my job and have decided to see
if there\'s a consistent and reliable way to interact with these models
on Apple devices without sacrificing privacy or requiring in-depth
technical setup.
My requirements for this test:
- Open source platform
- On-device model files
- Minimal required configuration
- Preferably pre-built, but a simple build process is acceptable
I tested a handful of apps and have summarized my favorite (so far) for
macOS and iOS below.
> TL;DR - Here are the two that met my requirements and I have found the
> easiest to install and use so far:
- macOS: [Ollama](https://ollama.ai/)
- iOS : [LLM Farm](https://llmfarm.site/)
# macOS
[Ollama](https://ollama.ai/) is a simple Go application for macOS and
Linux that can run various LLMs locally.
For macOS, you can download the pplication on the [Ollama download
page](https://ollama.ai/download/mac) and install it by unzipping the
`Ollama.app` file and moving it to the
`Applications` folder.
If you prefer the command line, you can run these commands after the
download finished:
```sh
cd ~/Downloads && \
unzip Ollama-darwin.zip && \
mv ~/Downloads/Ollama.app /Applications/
```
After running the app, the app will ask you to open a terminal and run
the default `llama2` model, which will open an interactive
chat session in the terminal. You can startfully using the application
at this point.
If you don\'t want to use the default `llama2` model, you can
download and run additional models found on the
[Models](https://ollama.ai/library) page.
To see the information for the currently-used model, you can run the
`/show info` command in the chat.
## Community Integrations
I highly recommend browsing the [Community
Integrations](https://github.com/jmorganca/ollama#community-integrations)
section of the project to see how you would prefer to extend Ollama
beyond a simple command-line interface. There are options for APIs,
browser UIs, advanced terminal configurations, and more.
# iOS
While there are a handful of decent macOS options, it was quite
difficult to find an iOS app that offered an open source platform
without an extensive configuration and building process. I found LLM
Farm to be decent enough in quality to sit at the top of my list -
however, it\'s definitely not user friendly enough for me to consider
using it on a daily basis.
[LLM Farm](https://llmfarm.site/) is available on TestFlight, so
there\'s no manual build process required. However, you can view the
[LLMFarm repository](https://github.com/guinmoon/LLMFarm) if you wish.
The caveat is that you will have to manually download the model files
from the links in the
[models.md](https://github.com/guinmoon/LLMFarm/blob/main/models.md)
file to your iPhone to use the app - there\'s currently no option in the
app to reach out and grab the latest version of any supported model.
Once you have a file downloaded, you simply create a new chat and select
the downloaded model file and ensure the inference matches the
requirement in the `models.md` file.
See below for a test of the ORCA Mini v3 model:

[Enchanted](https://github.com/AugustDev/enchanted) is also an iOS for
private AI models, but it requires a public-facing Ollama API, which did
not meet my \"on device requirement.\" Nonetheless, it\'s an interesting
looking app and I will likely set it up to test soon.
