From the livestream video, the tax part was incredibly impressive. After ingesting the entire tax code and a specific set of facts for a family and then calculating their taxes for them, it then was able to turn that all into a rhyming poem. Mind blown. Here it is in its entirety:

---

In the year of twenty-eighteen, Alice and Bob, a married team, Their income combined reached new heights, As they worked hard day and night.

Their son Charlie was their joy, A little baby, a lovely boy, A household they maintained together, Yet lived apart, without a tether.

To calculate their tax, it's true, A standard deduction we must construe, For married folks who file jointly, Twenty-four thousand dollars, quite pointy.

Their income sum, seventy-eight thousand nine eighty-one, Minus the standard deduction, the math's begum With exemptions being zero, the next line we trace, A taxable income of fifty-four thousand nine eighty-one takes place.

Now to the tax table, a liability we seek, For married couples, the outlook's not bleak, In range of thirty-six thousand nine to eighty-nine thousand one fifty, The formula's set, no longer shifty.

Five thousand five hundred thirty-five, it starts, Plus twenty-eight percent of the excess imparts, Eighteen thousand eighty-one, the difference we find, Multiplied by point two eight, the tax liability's designed.

Ten thousand five hundred ninety-seven dollars and sixty-eight cents, A tax liability for Alice and Bob, a sum quite dense, In this world of numbers, a story unfolds, Their financial journey, in a poem it's told.
