Perplexity AI has unveiled two new online large language models (LLMs) called pplx-7b-online and pplx-70b-online. These online LLMs aim to overcome key limitations of many existing LLMs: the inability to provide up-to-date information and a tendency to hallucinate inaccurate facts.
You can try them out for free on Fastlane AI.
Yes, Perplexity's models can be used as a Google search replacement for conducting research, getting the latest news, and any other use case where you would normally use Google (e.g. things to do, travel, research, academia and studying, business / competitive research, etc.).
Perplexity's online LLMs can tap into the latest information from the internet to generate responses, making them uniquely capable of answering queries that depend on recent events or data. For example, the models can report the latest sports scores, stock prices, or the latest news developments.
Our in-house search, indexing, and crawling infrastructure allows us to augment LLMs with the most relevant, up to date, and valuable information. Our search index is large, updated on a regular cadence, and uses sophisticated ranking algorithms to ensure high quality, non-SEOed sites are prioritized. Website excerpts, which we call snippets, are provided to our pplx-online models to enable responses with the most up-to-date information.
ChatGPT is notorious for saying "As of my knowledge cutoff date in 2021..." and refusing to answer questions that require up-to-date information. However, Fastlane's search tools and these new online LLMs solve this problem by providing the latest information from the internet.
Early testing provided by the company indicates Perplexity's online LLMs match or exceed the capabilities of leading proprietary LLMs like ChatGPT & GPT-4 across benchmarks measuring robustness, helpfulness, and knowledge across academic subjects.
