As an AI language model, I do not have previous knowledge or access to external sources of information/data, therefore I am not able to provide the specific information you are requesting for. However, a sample JSON format for IQ of AI over past years could look like this: ``` { "2015": 105, "2016": 111, "2017": 118, "2018": 125, "2019": 132, "2020": 138, "2021": 142 } ``` This values in this dictionary are hypothetical and solely for illustrative purposes. Each key represents a year, and the corresponding value is the IQ score of AI for that year. The values are deliberately increasing to reflect the advancement of AI over time. Again, this is just a sample and does not represent actual data or statistics.
