SDK Reference

TrainLoop Evals provides SDKs for multiple languages to instrument your LLM applications with zero-touch instrumentation.

Installation​

Choose your language:

# Python
pip install trainloop-sdk

# TypeScript/Node.js
npm install @trainloop/sdk

# Go
go get github.com/trainloop/sdk-go

Quick Start​

All SDKs follow the same pattern - initialize once, then your LLM calls are automatically instrumented:

# Python
import trainloop
trainloop.init(endpoint="http://localhost:8000")
// TypeScript
import trainloop from '@trainloop/sdk';
trainloop.init({ endpoint: 'http://localhost:8000' });
// Go
trainloop.Init(trainloop.Config{
    Endpoint: "http://localhost:8000",
})

Core Features​

All SDKs provide the same functionality:

  • Zero-touch instrumentation: Automatically capture LLM requests and responses
  • HTTP-based collection: Simple HTTP endpoint to collect traces
  • Framework agnostic: Works with any LLM library or framework
  • Minimal overhead: Designed for production use with minimal performance impact
