Chat with a model hosted on perplexity.ai
Description
Sign up at https://www.perplexity.ai.
Perplexity AI is a platform for running LLMs that are capable of searching the web in real-time to help them answer questions with information that may not have been available when the model was trained.
This function is a lightweight wrapper around chat_openai()
with
the defaults tweaked for Perplexity AI.
Usage
chat_perplexity(
system_prompt = NULL,
base_url = "https://api.perplexity.ai/",
api_key = perplexity_key(),
model = NULL,
seed = NULL,
api_args = list(),
echo = NULL
)
Arguments
system_prompt |
A system prompt to set the behavior of the assistant. |
base_url |
The base URL to the endpoint; the default uses OpenAI. |
api_key |
API key to use for authentication. You generally should not supply this directly, but instead set the |
model |
The model to use for the chat (defaults to "llama-3.1-sonar-small-128k-online"). We regularly update the default, so we strongly recommend explicitly specifying a model for anything other than casual use. |
seed |
Optional integer seed that ChatGPT uses to try and make output more reproducible. |
api_args |
Named list of arbitrary extra arguments appended to the body
of every chat API call. Combined with the body object generated by ellmer
with |
echo |
One of the following options:

Value
