Adaptive Reasoning with Gemini 3 Flash: A LangGraph MCP Agent for Cost-Optimized Analytics
This challenge focuses on building an intelligent agent system. You will design and implement a graph-based workflow using LangGraph that dynamically switches between Gemini 3 Flash (for speed and cost-efficiency) and Gemini 2.5 Pro (for deeper, more complex reasoning tasks). The system must employ MCP-enabled tool integration to access enterprise data sources and make informed decisions on model selection, ensuring optimal resource allocation for analytical tasks like market trend analysis or customer feedback summarization. The goal is to achieve high-quality insights while meticulously managing operational costs.
