It seems that GPT-4 Turbo, the most recent incarnation of the Large Language Model (LLM) from OpenAI, winds down for the winter and gives worse answers to questions in much the same way that people who are winding down for the December holidays seem to do.
We all get those end of year holiday season chill vibes and, after a new study, that appears to be why GPT-4 Turbo seems to be giving worse answers because when it’s been trained on datasets from December it seems to have “learned” that humans do worse work and then “adopted” those same behaviours. Weird I know right!?
The Future of AI and Generative AI, by Keynote Matthew Griffin
As Wccftech highlighted, the interesting observation on the AI’s behavior was made by an LLM enthusiast, Rob Lynch, on X (formerly Twitter).
The claim is that GPT-4 Turbo produces shorter responses, to a statistically significant extent, when the Artificial Intelligence (AI) believes that it’s December, as opposed to May, with the testing done by changing the date in the system prompt.
So, the tentative conclusion is that it appears GPT-4 Turbo learns this behaviour from us, an idea advanced by Ethan Mollick who’s an Associate Professor at the Wharton School of the University of Pennsylvania who specializes in AI.
Apparently GPT-4 Turbo is about 5% less productive if the AI thinks it’s the Holiday season. This is known as the ‘AI winter break hypothesis’ and it’s an area that is worth exploring further. Because not only is it odd but, yet again, it shows how oddly and unexpectedly AI’s can behave …
What it goes to show is how unintended influences can be picked up by an AI that we wouldn’t dream of considering, although some researchers obviously did notice and consider it, and then test it. But still, you get what I mean, and there’s a whole lot of worry around these kinds of unexpected developments.
As AI progresses, its influences, and the direction that the tech takes itself in, need careful watching over, hence all the talk of safeguards for AI being vital. We’re rushing ahead with developing AI, or rather, the likes of Google, Microsoft, and OpenAI certainly are, caught up in a tech arms race, with most of the focus on driving progress as hard as possible, with safeguards being more of an afterthought.
At any rate, regarding this specific experiment, it’s just one piece of evidence that the winter break theory is true for GPT-4 Turbo, and Lynch has urged others to get in touch if they can reproduce the results, and we do have one report of a successful reproduction so far. Still, that’s not enough for a concrete conclusion yet, watch this space.
What this means for your organisation
Unseen habits can shape outputs.
Tests found GPT-4 Turbo wrote shorter answers when the system prompt said December instead of May. The gap was about 5% in productivity. Large language models can pick up traits from their training data that nobody planned for.
Treat the finding as a hypothesis.
This is one experiment, with one reported reproduction so far. Rob Lynch has asked others to try to repeat it. Run your own checks and record the date and prompt settings used, so odd drops in quality can be traced.
Safeguards still trail the race.
Google, Microsoft and OpenAI are caught in a tech arms race, and safeguards are often an afterthought. 311 rates large language models as Act now, with wide use from 2024. Leaders should set their own monitoring rules before relying on them at scale.
Three questions for your next leadership meeting
- Do we test our AI tools at different times of year?
- Who checks our AI outputs for drops in length or quality?
- What safeguards do we require before an AI tool is used at scale?
