Perplexity's default model, used as thefoundation modelfor its standard search, is an in-house modification of Meta's Llama 3 called Sonar. But Perplexity also offers access to several other LLMs for more advan
Perplexity AI is an AI-driven search engine and chatbot that uses large language models (LLMs) to answer user queries by drawing information from the web and providing cited sources within its responses. Similar to ChatGPT Search, the model combines a traditional search engine with an AI assist...

simulation of human intelligence processes by machines, especially computer systems. It includes learning, reasoning, and self-correction. Examples of AI applications includeexpert systems, natural language processing (NLP),speech recognition,machine vision, and generative tools like ChatGPT and Perplexity....
Once a model is trained, it is important to evaluate its performance using metrics like perplexity, accuracy, and loss functions. Tools that assist these evaluations help developers refine the model and assess its readiness for deployment.
However, it was noted that the quality of information is occasionally conveyed using complex language. LLMs have considerable potential as assistive tools in the management of urolithiasis; however, their limitations necessitate expert supervision, especially in complex cases. In the future, it is ...
1). Token- level probability (TokenProbs for short), proposed in (Manakul et al., 2023), measures the response’s likelihood and the average of the token probabilities is used as the confidence score; 2). Perplexity, the reciprocal of the (normalized) language model probability, is used...
