LangChain - Fundamentals

AUse LangGraph to deploy, LangServe to track runs, and LangSmith to visualize flow

BUse LangSmith to deploy, LangGraph to track runs, and LangServe to visualize flow

CUse LangServe to deploy, LangSmith to track runs, and LangGraph to visualize flow

DUse LangServe to track runs, LangGraph to deploy, and LangSmith to visualize flow

Step-by-Step Solution

Solution:

Step 1: Match each tool to its function and arrange tools in correct usage order
LangServe deploys apps, LangSmith tracks and logs runs, LangGraph visualizes the app's task flow. First deploy with LangServe, then track runs with LangSmith, and visualize with LangGraph.
Final Answer:
Use LangServe to deploy, LangSmith to track runs, and LangGraph to visualize flow -> Option C
Quick Check:
Deploy, track, visualize = Serve, Smith, Graph [OK]

Quick Trick: Deploy with Serve, track with Smith, visualize with Graph [OK]
