Introduction

We are excited to announce that Langtrace now offers comprehensive support for OpenAI's new Responses API, featuring full OpenTelemetry (OTEL) compatibility. This integration enhances your ability to monitor and trace AI-driven applications, providing deeper insights and greater flexibility.

Why This Matters

  • OpenTelemetry (OTEL) Compatibility: With OTEL support, Langtrace ensures that traces are standardized, allowing for seamless integration with various observability platforms. This standardization facilitates richer metadata capture, aiding in debugging and performance optimization.

  • Simplified Integration: Incorporating Langtrace into your OpenAI Responses API setup is straightforward. With minimal configuration, you can begin collecting valuable trace data without extensive modifications to your existing codebase.

  • Flexibility and Vendor Independence: Langtrace's adherence to OTEL standards means you're not confined to a single observability vendor. You have the freedom to route your trace data to any OTEL-compatible backend, such as Elastic APM, Grafana Labs, Datadog, and more, based on your preferences and requirements.

Getting Started

To leverage Langtrace's support for OpenAI's Responses API, follow these steps:

  1. Install the Langtrace SDK: Add the Langtrace SDK to your project to enable tracing capabilities.


    pip install langtrace-python-sdk


  2. Initialize the SDK: Set up the SDK with your Langtrace API key to authenticate and configure tracing.


    # Import it into your project
    from langtrace_python_sdk import langtrace # Must precede any llm module imports
    
    langtrace.init(api_key = '<LANGTRACE_API_KEY>')


  3. Integrate with OpenAI's Responses API: Utilize the Responses API as you normally would. Langtrace will automatically capture traces, providing insights into your AI application's performance and behavior.
