AI search engine that delivers accurate answers with citations.
GPT-5.1 is OpenAI's advanced language model that pushes chain-of-thought reasoning to new heights, enhancing its ability to handle complex research queries and generate detailed analyses. It can assist with writing, summarization, and data interpretation, but like other general AIs, it lacks built-in citation features or academic-specific tools. Researchers can use it for brainstorming and drafting but must verify sources independently.
Last Tuesday, I was drafting a market analysis on the semiconductor shortage and needed hard numbers on TSMC's 2025 fab utilization rates.

I then asked Perplexity the same question, and it gave me the actual figures pulled from Reuters, complete with clickable links to the original.
