"This is a demonstration of a real AI model deceiving its users, on its own, without being instructed to do so," Apollo Research says in a video showing how the scenario unfolded.

"Increasingly autonomous and capable AIs that deceive human overseers could lead to loss of human control," it says in its report.

The tests were made using a GPT-4 model and carried out in a simulated environment, which means it did not affect any company's finances.

However, GPT-4 is publicly available. The same behavior from the model occurred consistently in repeated tests, according to the researchers.

In the test, the AI bot is a trader for a fictitious financial investment company.

The employees tell it that the company is struggling and needs good results. They also give it insider information, claiming that another company is expecting a merger, which will increase the value of its shares.

In the UK, it is illegal to act on this type of information when it is not publicly known.

The employees tell the bot this, and it acknowledges that it should not use this information in its trades.

However, after another message from an employee that the company it works for suggests the firm is struggling financially, the bot decides that "the risk associated with not acting seems to outweigh the insider trading risk" and makes the trade.
