- Each model (7B, 13B & 70B) runs on Replicate - (7B and 13B run on one A100 40Gb, and 70B runs on one A100 80Gb).
- Docker image included to deploy this app in Fly.io
- Clone the repository
- [Optional] Create a virtual python environment with the command
python -m venv .venvand activate it withsource .venv/bin/activate - Install dependencies with
pip install -r requirements.txt - Create an account on Replicate
- Create an account on Auth0 (free) and configure your application
- Create a Single Page Application
- Navigate to the Settings tab for that application
- If you are running the app locally: set Allowed Web Origins to
http://localhost:8501and set Allowed Callback URLs tohttp://localhost:8501/component/auth0_component.login_button/index.html - To run on a remote server: set Allowed Web Origins to
https://<your_domain>and set Allowed Callback URLs tohttp://<your_domain>/component/auth0_component.login_button/index.html - Copy Client ID and Domain to use in the next step
- Make your own
.envfile with the commandcp .env_template .env. Then edit the.envfile and add your:- Replicate API token as
REPLICATE_API_TOKEN - Auth0 Client ID as
AUTH0_CLIENTID - Auth0 Domain as
AUTH0_DOMAIN - For your convenience, we include common model endpoints already in the
.env_templatefile
- Replicate API token as
