问题

Managing API rate limits while running a multi-agent debate application.

结果

The app demonstrates a resilient multi‑agent debate system that automatically switches LLM providers on rate‑limit errors, maintaining continuous operation and providing a polished UI with transcript export and usage monitoring.

工作流

• Configure multiple LLM providers in llm_factory.py
• Wrap providers with FallbackLLMWrapper
• Run debate agents via LangGraph state machine
• If a 429 error occurs, wrapper routes prompt to next provider
• Continue debate until verdict is generated
• Export transcript as PDF or Markdown
• Display real‑time API call counter in sidebar

证据

If the primary LLM throws a 429 Too Many Requests error, the wrapper catches it and immediately routes the prompt to the next available provider in the list.
