Let's discuss what Jarvis knows and what you can expect of him as he generates content for you!
The underlying AI model that powers Jarvis was trained by reading about 10% of the published internet, with the goal of understanding how people write. Jarvis has read millions of blog posts, Reddit threads, websites, newspapers, and more. This gives Jarvis an unbelievable grasp of imitating human language and creating content most find exceptional.
The base training was completed at the end of 2019. That means Jarvis doesn't know about current events from January 2020 and beyond. Jarvis doesn't know COVID-19 happened.
This is the point some will say, "Jarvis can't help me then! I write topics that are new since 2019!"
While Jarvis may not know about COVID-19 or that the Lakers won the 2020 NBA Championship, he does know vast amounts about coronaviruses, pandemics, Wuhan, SARS, Lebron James, Basketball, The Lakers, and NBA. By feeding Jarvis updated information about the topic you're writing about, you'll see Jarvis can typically do a great job of writing about it.
For example, if I wanted Jarvis to write about COVID-19, I would include up-to-date information in the content description.
If I wanted to write about the Lakers winning the 2020 NBA championship I would provide information like this.
As with all text Jarvis writes, it's likely that he will still make up some facts that you'll want to correct, but seeding him with correct information will greatly increase the chances of him writing true information.
Keep in mind that the content description should be changed throughout the writing of a document. Because what is in the content description impacts the content Jarvis writes each time you hit compose, Jarvis will tend to repeat that information over and over if you don't update the content description box.
Rather, you should think of the content description box inside a document as the information you want Jarvis to use each time he composes text. You could be updating that for each paragraph of a document you're writing.
