FastGPT was launched by Kagi Search today. Kagi says FastGPT is a proof of concept built to answer the question, “What is the fastest possible AI answering engine that runs a full search engine underneath?”. The AI appears to be using Claude by Anthropic.
Typically, FastGPT will start outputting answers in 900ms. FastGPT is best used to retrieve a general topic summary from the web. The processing is optimized for speed, not necessarily the maximum possible accuracy (which would require more processing time).
