Note: we’ve temporarily stopped development on the open-source version of OpenPipe to integrate some proprietary third-party code. We hope to make the non-proprietary parts of the repository open again under an open core model once we have the bandwidth to do so!

OpenPipe

Open-source fine-tuning and model-hosting platform.

Demo - Running Locally - Docs

Features

• Easy integration with OpenAI's SDK in both Python and TypeScript.

Running Locally

1. Install Postgresql.
2. Install NodeJS 20 (earlier versions will very likely work but aren't tested).
3. Install pnpm: npm i -g pnpm
4. Clone this repository: git clone https://github.com/openpipe/openpipe
5. Install the dependencies: cd openpipe && pnpm install
6. Create a .env file (cd app && cp .env.example .env) and enter your OPENAI_API_KEY.
7. If you just installed postgres and wish to use the default DATABASE_URL run the following commands:

psql postgres
CREATE ROLE postgres WITH LOGIN PASSWORD 'postgres';
ALTER ROLE postgres SUPERUSER;

8. Update DATABASE_URL if necessary to point to your Postgres instance an
