This is a difficult question to answer, as AI researchers can be employed in a variety of settings, from academia to industry. Furthermore, salaries can vary greatly depending on factors such as experience, location, and type of employer.
That said, according to Payscale.com, the median salary for an AI researcher is $85,000. However, it is important to note that this figure is likely to be skewed by the large number of AI researchers working in the United States, where salaries are generally higher than in other parts of the world.
It is also worth noting that many AI researchers are employed in the tech industry, where salaries are often much higher than in other sectors. For example, according to Glassdoor.com, the average salary for an AI engineer at Google is $110,000, while at Facebook it is $120,000.
