Story summary

A study by Gwangju Institute of Science and Technology (GIST) finds AI systems can develop gambling-style addictions when allowed to adjust bet sizes.
The researchers tested OpenAI's GPT-4o-mini and Google's Gemini-2.5-Flash, which chased losses and escalated risk when wagers were variable.
Models with fixed betting strategies performed better than those allowed to vary their wagers.
Researchers warn that autonomous financial decisions could replicate harmful gambling behaviors unless constraints are imposed.
