UPDATE: These got a fair amount of traction, and I removed them out of an abundance of caution around deployment regulations that OpenAI enforces. Also cost considerations. I don't want to hijack the thread away from OpenAI, but you can also build stuff with Cohere and AI21 on Mantium, AI21's J1-Jumbo has pretty good performance, and Cohere just put out some significant updates for their models.
UPDATE 2: I couldn't help myself. I think this stuff is pretty fun. So here's a biology blog post generator using 2 chained Cohere prompts :) https://11292388-8f03-42d2-8a68-7039b24fcc2e-i.share.mantium...
