Perplexity equips agents with a specialized tool for efficiently gathering source-backed information from the internet, ideal for scenarios requiring research, fact-checking, or contextual data to inform decisions and responses. Each response includes citations, which provide transparent references to the sources used for the generated answer, and choices, which contain the model's suggested responses, enabling users to access reliable information and diverse perspectives. This function may encounter timeout errors due to long processing times, but retrying the operation can lead to successful completion. [Response structure] - id: An ID generated uniquely for each response. - model: The model used to generate the response. - object: The object type, which always equals `chat.completion`. - created: The Unix timestamp (in seconds) of when the completion was created. - citations[]: Citations for the generated answer. - choices[]: The list of completion choices the model generated for the input prompt. - usage: Usage statistics for the completion request.
