Overview of Langtrace

Langtrace: Open Source Observability and Evaluations Platform for AI Agents

What is Langtrace?

Langtrace is an open-source platform designed to provide observability and evaluation capabilities for AI agents, particularly those powered by Large Language Models (LLMs). It helps developers and organizations measure performance, improve security, and iterate towards better and safer AI agent deployments.

How does Langtrace work?

Langtrace works by integrating with your AI agent's code using simple SDKs in Python and TypeScript. It then traces and monitors various aspects of the agent's operation, including:

  • Token usage and cost: Track the number of tokens used and the associated cost.
  • Inference latency: Measure the time taken for the agent to generate responses.
  • Accuracy: Evaluate the accuracy of the agent's outputs using automated evaluations and curated datasets.
  • API Requests: Automatically trace your GenAI stack and surface relevant metadata

This data is then visualized in dashboards, allowing you to gain insights into your agent's performance and identify areas for improvement. Key Features

  • Simple Setup: Langtrace offers a non-intrusive setup that can be integrated with just a few lines of code.
  • Real-Time Monitoring: Dashboards provide real-time insights into key metrics like token usage, cost, latency, and accuracy.
  • Evaluations: Langtrace facilitates the measurement of baseline performance and the creation of datasets for automated evaluations and fine-tuning.
  • Prompt Version Control: Store, version control, and compare the performance of prompts across different models using the playground.
  • Enterprise-Grade Security: Langtrace provides industry-leading security protocols and is SOC2 Type II certified.
  • Open Source: The open-source nature of Langtrace allows for customization, auditing, and community contributions.

Supported Frameworks and Integrations

Langtrace supports a variety of popular LLM frameworks and vector databases, including:

  • CrewAI
  • DSPy
  • LlamaIndex
  • Langchain
  • Wide range of LLM providers
  • VectorDBs

Deploying Langtrace

Deploying Langtrace is straightforward. It involves creating a project, generating an API key, and installing the appropriate SDK. The SDK is then instantiated with the API key. Code examples are available for both Python and TypeScript.

Why is Langtrace important?

Langtrace is important because it helps address the challenges of deploying AI agents in real-world scenarios. By providing observability and evaluation capabilities, Langtrace enables organizations to:

  • Improve performance: Identify and address performance bottlenecks.
  • Reduce costs: Optimize token usage and minimize expenses.
  • Enhance security: Protect data with enterprise-grade security protocols.
  • Ensure compliance: Meet stringent compliance requirements for data protection.

Who is Langtrace for?

Langtrace is for any organization or individual developing and deploying AI agents, including:

  • AI developers
  • Machine learning engineers
  • Data scientists
  • Enterprises adopting AI
