I don’t remember the institution, but I remember reading a paper on a simulated trading environment with several ai agents who didn’t know about eachother. The LLMs were pretty conservative with profits and deliberately bought and sold in predictable ways. They all ended up “colluding” with eachother by deliberately not competing.











I usually give up or find a free alternative. Typically, if something is available at a good price I won’t bother trying to get it free to begin with.
