Hey, I'm Tanish from Langchain. Today I'm going to go through how to use Open Router's new broadcast feature with Langchain to send traces to Langmith. The cool thing about broadcast is it stores destination information, which in this case is Langmith server side.So the only thing that you need to worry about in your code is your open router API key. Let's go through how to set this up. So let me walk you through a quick code snippet.This uses lang chain's init chat model in order to initialize a model and ...

Data Security Incident - A DOGE staffer with access to Americans' personal data leaked a private xAI API key [1] Technology and Privacy - The incident highlights potential vulnerabilities in data security practices within organizations handling sensitive user information [1]

Langsmith Platform Overview - Langsmith is an observability and evaluation platform for AI applications, focusing on tracing application behavior [1] - The platform uses tracing projects to collect logs associated with applications, with each project corresponding to an application [2] - Langsmith is framework agnostic, designed to monitor AI applications regardless of the underlying build [5] Tracing and Monitoring AI Applications - Tracing is enabled by importing environment variables, including Langmouth tracing, Langmith endpoint, and API key [6] - The traceable decorator is added to functions to enable tracing within the application [8] - Langsmith provides a detailed breakdown of each step within the application, known as the run tree, showing inputs, outputs, and telemetry [12][14] - Telemetry includes token cost and latency of each step, visualized through a waterfall view to identify latency sources [14][15] Integration with Langchain and Langraph - Langchain and Langraph, Langchain's open-source libraries, work out of the box with Langsmith, simplifying tracing setup [17] - When using Langraph or Langchain, the traceable decorator is not required, streamlining the tracing process [17]
