PromptBase news and media highlights

The wild world of PromptBase, the eBay for generative AI prompts

The old saying is that the best person to be in a gold rush is the one selling the shovels. Well, what about the person who owns the shovel store? It’s not far off from what developer Ben Stokes is currently doing within the booming world of generative artificial intelligence right now. Stokes didn’t make another AI tool. Instead, he’s running a marketplace for the prompts that go into the AI. It’s called PromptBase, and according to Stokes, there’s been a lot of early interest.

A startup is charging $1.99 for strings of text to feed to DALL-E 2

Figuring out the right text prompts to yield the best results with AI systems like OpenAI’s DALL-E 2 has become a science in its own right. Now a startup is looking to let “prompt engineers” cash in with an online marketplace that sells these finely tuned phrases. PromptBase, launched in June, allows users to sell strings of words that net predictable results with particular systems. Priced at $1.99 — PromptBase takes a 20% cut — the content that the prompts generate range from “viral” headlines to pictures of sports team logos, knitted dolls and animals wearing suits.
