Several former Google AI researchers such as Andy, Srinivas, Yarats, Ho have founded a startup Perplexity AI which is responsible for chatbot Perplexity Co-pilot. This has the potential to be a market leader in web search combining web index and chatbot interface. It can affect the market leader Google’s position. It has also released its LLMs-pplx-7b-online and pplx-70b-online where the digits indicate their parameter sizes. They are fine-tuned and augmented versions of open-source models from Mistral and Mela. Parameters refer to the number of connections between model’s artificial neurons. They indicate how ‘intelligent’ and powerful the modes are. The higher the parameters, the more knowledgeable the model.

They have Perplexity API so that others can use and build their own apps.

They also offer helpful, factual and uptodate information.
