So far I have found Bard to be significantly worse at some basic tasks. A simple request to give me the text of the opening scene of King Lear met with a badly comical rewrite in modern prose that got basic things wrong (all the daughters professed their love for their father a and received equal shares of land & dowry) I point out the inaccuracy and reinforced my request for the exact verbatim text. And then proceeded to give— still— a rewritten version albeit slightly closer to the true text. Bing and ChatGPT both complied on the first try.
On the other hand, bard performed much better at a more complex task: I provided fake data spanning six years and a few rows of different categories. I left the sixth year blank. Without prompting it, reformatted the from comma do you limited into a nice table. It also gave a brief summarization and analysis of the trends. When I asked follow-up questions he gave detailed responses that were moderately insightful for anyone that would be familiar with the data domain given a few minutes to review the data set. Finally, I asked it to give a projection of what the values would be for the final column, which I had left blank. It did so, with an explanation of the trend it observed, as well as a description of the linear regression model. It used it and apologized for not being able to give more complex modeling due to the Small data set.
GPT-4 provided answers and analysis that were comparable in quality, but required additional rounds of prompting and clarification.
