Learn to build an intelligent conversational AI agent by leveraging LlamaIndex to dynamically orchestrate and route prompts between OpenAI and Anthropic APIs.
Prerequisites
- Python 3.10 or newer
- API keys for OpenAI and Anthropic
- Intermediate knowledge of Python and asynchronous programming
What We’re Building
In this tutorial, we will construct an agentic conversational AI companion using LlamaIndex. Instead of using primitive hardcoded logic to route user intent, we will use a ReAct (Reasoning and Acting) agent loop. This workflow allows the core engine to evaluate a user’s prompt and dynamically choose whether to delegate the task to OpenAI’s GPT-4o or Anthropic’s Claude 3.5 Sonnet.
