To update or switch versions, run webi ollama@stable (or @v0.1.5, etc).

Cheat Sheet

ollama is an LLM serving platform written in golang. It makes LLMs built on Llama standards easy to run with an API.

To get started quickly with the open source LLM Mistral-7b as an example is two commands.

1. Open TWO Terminals
2. In the first, start the ollama server

   OLLAMA_ORIGINS='*' OLLAMA_HOST=localhost:11434 ollama serve
   

3. In the second, run the ollama CLI (using the Mistral-7b model)

   ollama pull mistral
   ollama run mistral

Files

These are the files / directories that are created and/or modified with this install:

~/.config/envman/PATH.env
~/.local/bin/ollama
~/.ollama/models/

How to Use a ChatGPT-style Web Interface

There are many Ollama UIs to choose from, but ollama-webui is easy to start with (and can be built as a static page):

1. Install node

   webi node@lts
   source ~/.config/envman/PATH.env
   

2. Clone and enter the ollama-webui repo

   git clone https://github.com/ollama-webui/ollama-webui.git ./ollama-webui/
   pushd ./ollama-webui/
   

3. Install and start the project

   cp -RPp ./example.env ./.env
   npm clean-install
   npm run dev
   

4. Enjoy!
   • http://localhost:5173/

Note: Be sure to run ollama with CORS enabled:

OLLAMA_ORIGINS='*' OLLAMA_HOST=localhost:11434 ollama serve

System Notes

You'll need a fairly modern computer. An Apple M1 Air works great.

• 8GB+ RAM
• 4GB+ Storage
• Models range between 3GB and 30GB+
  (they can take a while to download, and several seconds to initialize)

How to Downloads Other Models

See the list at https://ollama.ai/library.

For example, we could try sqlcoder, or orca-mini (because it's small):

ollama pull sqlcoder
ollama run sqlcoder

ollama pull orca-mini
ollama run orca-mini

How to Use as an API on a Network

If you'd like ollama to be accessible beyond localhost (127.0.0.1):

• set the host to 0.0.0.0, which makes it accessible to ALL networks
• you may wish to limit origins

# fully open to all
OLLAMA_ORIGINS='*' OLLAMA_HOST=0.0.0.0:11435 ollama serve

# restrict browsers (not APIs) to requests from https://example.com
OLLAMA_ORIGINS='https://example.com' OLLAMA_HOST=0.0.0.0:11435 ollama serve
