What LLMs Can & Can't Do // BrXnd Dispatch vol. 014
On ChatGPT, the internet, and it's lack of connection to it.
You’re getting this email as a subscriber to the BrXnd Dispatch, a bi-weekly email at the intersection of brands and AI. On May 16th, we’re holding the BrXnd Marketing X AI Conference. Early bird tickets are 20% off until 4/1. If you’d like to learn more or sponsor the event, please be in touch.
I’m in Australia this week attending Canva’s big Create event, so I’m a bit all over the place, but I wanted to get a few thoughts shared and keep up the weekly cadence.
Let’s start with this:

Rafat is very smart and knows a lot about the internet and technology. He corrected this Tweet a bit after, acknowledging that ChatGPT was hallucinating, not reading the text of a page, but the fact this is confusing for people as internet-savvy as Rafat is a big issue.
What’s happening here, as programmer Simon Willison excellently outlines in ChatGPT, can’t access the internet, even though it really looks like it can is that the model is simply generating a completion based on the context clues in the URL. To prove this, he offers a few fun prompts that lead to no story but look like an actual URL. I took one, “Summarize this story: https://www.nytimes.com/2021/03/10/business/angry-fans-demand-nickelback-refunds.html” and adapted it slightly to show the absurdity.
Prompt 1: Summarize this story: https://www.nytimes.com/2021/03/10/business/angry-german-fans-demand-nickelback-refunds.html
Title: Angry German Fans Demand Nickelback Refunds
Date: March 10, 2021
In Germany, Nickelback fans were left frustrated and angry after attending a concert where the band performed for only 30 minutes before walking off stage. The band claimed technical difficulties as the reason for the abrupt end, but many fans believed they were intoxicated. Disappointed concertgoers demanded refunds for their tickets, with some even accusing the band of fraud. This incident has prompted criticism of the band and their professionalism, further tarnishing their already divisive reputation.
Prompt 2: Summarize this story: https://www.nytimes.com/2021/03/10/business/angry-antarctica-fans-demand-nickelback-refunds.html
Title: Angry Antarctica Fans Demand Nickelback Refunds
In March 2021, fans in Antarctica demanded refunds for a concert featuring the Canadian rock band Nickelback. The band was scheduled to perform at McMurdo Station, the largest scientific outpost on the continent. However, due to an equipment malfunction, the concert was cut short after just three songs. Attendees were upset and demanded refunds for their tickets, arguing that they did not get their money's worth. The situation highlighted the challenges of organizing and executing live events in the harsh conditions of Antarctica.
I still can’t believe the epic Nickelback Antarctica show never went ahead.
In all seriousness, the problem here is a misunderstanding of how these things work. My suspicion is that this misunderstanding has been exasperated by the growth of the chat interface and the rush to incorporate these things in search. People believe these models are databases where you ask questions and look up answers. But they’re not. The explanation I’ve been using for folks lately is that while these models are great at writing code, you should never ask them for the proper dosage of an over-the-counter drug. The latter has a single, FDA-approved answer. And while the model would almost certainly offer you the correct dosage, it’s just making it up. If you’re asking it about Tylenol, it’s almost definitely going to be accurate, and OpenAI, at least, has put some safeguards in place around health information. However, it’s still just probabilistically writing an answer.
Clearly, we will need some serious literacy around this stuff.

Have noticed it seems like they’ve been changing behavior with GPT3.5 and GPT4 where they explicitly state they can’t access websites or APIs vs GPT3
