Perplexity AI is an AI chatbot-powered research and conversational search engine that answers queries using natural language predictive text.[2][3] Launched in 2022, Perplexity generates answers using sources from the web and cites links within the text response.[4] Perplexity works on a freemium model; the free product uses Anthropic's Claude 3 Haiku model combined with the company's standalone large language model (LLM) that incorporates natural language processing (NLP) capabilities, while the paid version Perplexity Pro has access to GPT-4, Claude 3, Mistral Large, Llama 3 and an Experimental Perplexity Model.[3][4][1] As of early 2024, it has about 10 million monthly users.

Perplexity - Wikipedia

In information theory, perplexity is a measure of uncertainty in the value of a sample from a discrete probability distribution. The larger the perplexity, the less likely it is that an observer can guess the value which will be drawn from the distribution.

rust-free concrete: Fiberglas Rebar | Owens Corning

Concrete: A Ticking Time Bomb. Can We Fix It? - YouTube

reinforced concrete has one dark secret, RUST, which we're taking a look at in this video, alongside multiple other problems. Is there a way to use concrete in better ways?

Fiberglas™ Rebar | Owens Corning

Leave the rust and weight of traditional steel behind for a lighter weight, stronger, rustproof concrete reinforcement.

Designed with DOTs (Department of Transportation), engineers and contractors in mind, Fiberglas™ Rebar by Owens Corning Infrastructure Solutions is setting a new bar in concrete reinforcement.

PINKBAR® Fiberglas™ Rebar vs. Steel

Fiberglass Rebar – also known as FRP, GFRP or Composite Rebar – is a more durable, proven and successful reinforcing alternative to steel.


2X the tensile strength compared to steel


Up to 7x lighter in concrete flatwork applications

4x lighter compared to the same size diameter


Fiberglass rebar will never rust, enabling more durable structures
