Laminar is an open-source platform designed to provide observability, analytics, evaluations, and prompt chains for complex LLM (Large Language Model) applications. Essentially, it combines the functionalities of DataDog and PostHog but is tailored specifically for LLM applications. Written in Rust, Laminar promises to be fast, reliable, and insightful. The project is currently in progress and will see frequent updates.
Laminar Cloud
The easiest way to get started with Laminar is through the Laminar Cloud, which offers a generous free tier on its managed platform. You can access it at lmnr.ai.
Self-Hosting with Docker Compose
For those who prefer self-hosting, Laminar can be started locally using Docker Compose. This setup will spin up several containers necessary for running Laminar.
Instrumenting Python Code
To get started with instrumenting your Python code, you need to:
Create a project and generate a Project API Key.
Automatically instrument LLM calls of popular frameworks and LLM provider libraries by adding specific configurations.
Use the @observe() decorator to trace inputs and outputs of functions.
You can send events in two ways, and to run an evaluation event, you need to create an evaluator pipeline and a target version for it. Laminar processes background job queues of pipeline processes and records outputs as events.
Creating and Managing Pipelines
Laminar allows you to create pipelines in the UI and manage chains of LLM calls. Once your pipeline is ready, you can deploy it by selecting the target version. You can then call it from Python with just a few lines of code.
