AI Roundup: Wharton's crash course in generative AI


Wharton's crash course on generative AI. This five-video series from Wharton Interactive’s Ethan Mollick and Lilach Mollick is less than an hour long, but it packs in a ton of information: What is generative AI, anyway? What are the best AI tools available today? How can you prompt AI most effectively? (If you're pressed for time, you can skip the last two videos, which are targeted at students and teachers … but aren't we all learning or teaching something?)

Score a win for 'Dr. ChatGPT.A young boy's painful symptoms baffled 17 doctors across three years … until his mom entered his symptoms into ChatGPT. The AI immediately proposed a diagnosis of tethered cord syndrome, which was later confirmed by a neurosurgeon. Despite this success story, experts warn that ChatGPT remains error-prone and has not been validated in a clinical setting.

  • Previously: A study in JAMA found that GPT-4 performed well, if imperfectly, in diagnosing complex clinical case studies.

Should you ask your AI to 'take a deep breath'? If you've read about prompt engineering, you know that the exact words you use in prompting AI can make a big difference in the quality of its response. For this new paper, researchers used AI models to, well, optimize AI prompts (yes, this all feels very Inception-y). Some of the best-performing prompts were downright weird: One advised the AI to "take a deep breath" before replying.

  • Analysis: It's striking that AI is already optimizing its own prompts. I suspect that, in a few years, most users won't need to bother with "prompt engineering" at all, since AI will be able to translate even clunky requests into well-specified prompts.

How to get the best AI-written summaries? Just. Keep. Asking. This intriguing working paper proposes a method called "chain of destiny" prompting to help AI create information-packed content summaries. It asks the AI to work through an iterative series of steps:

(1)    Draft a summary of a document.

(2)    Identify several elements from the source document that are missing in the draft summary.

(3)    Integrate the missing elements without adding any words to the summary.

(4)    Repeat steps 2 and 3 again … and again … and again.

The resulting summaries are quite rich and information-dense (perhaps too information-dense for comfortable reading). But what mostly interests me here is the approach: Rather than treating AI's first output as a finished product, the researchers treat it as an early draft that the AI can independently critique and improve upon. It’s a method that holds promise for many, many use cases.
