Risks and harms 🛑

Microsoft's Copilot chatbot has been criticised for perpetuating biases, and generating facilitating unethical or inappropriate content, including misinformation, amongst others.


Copilot is easily made to change personality; it also gets confused, repetitive, or prone to being provoked and belligerent if it is asked too many questions.

Mis- and disinformation

Like other generative AI systems, Copilot produces inaccurate, misleading, and false information.


Bing Chat has been criticised for its poor safety record. Amongst other things, the bot:  


Bing Chat/Microsoft Copilot have been found to be susceptible to jailbreaking so-called 'prompt injections'. 

Transparency 🙈

Microsoft acknowledged that Bing Chat had many limitations and posed many risks, and published regular updates on what it was doing to get Bing Chat behave more in line with users' expectations.

It appeared Microsoft may have surreptitiously tested a prototype of Bing Chat using OpenAI's GPT-4 large language model on users in India and some other countries in the wild without informing them in November 2022.
