Example of integration with [mckaywrigley/chatbot-ui](https://github.com/mckaywrigley/chatbot-ui). |
||||
|
||||
 |
||||
|
||||
## Setup |
||||
|
||||
```bash |
||||
# Clone LocalAI |
||||
git clone https://github.com/go-skynet/LocalAI |
||||
|
||||
cd LocalAI/examples/chatbot-ui |
||||
|
||||
# (optional) Checkout a specific LocalAI tag |
||||
# git checkout -b build <TAG> |
||||
|
||||
# Download gpt4all-j to models/ |
||||
wget https://gpt4all.io/models/ggml-gpt4all-j.bin -O models/ggml-gpt4all-j |
||||
|
||||
# start with docker-compose |
||||
docker compose up -d --build |
||||
``` |
||||
|
||||
Open http://localhost:3000 for the Web UI. |
