GPT Researcher supports Exa as a retriever for its deep-research loop. Set the retriever selection to exa so research tasks discover and collect sources through Exa.
How to enable Exa in GPT Researcher:
Set RETRIEVER to exa in the GPT Researcher environment.
Provide EXA_API_KEY in the project environment.
Run GPT Researcher’s normal deep-research workflow; Exa supplies the retrieval layer.
