Can Chinese AI (Kimi K3) file American tax returns (TaxCalcBench)?

For those looking for the answer that don’t want to click through the entire repo: no. Kimi cannot do your American taxes, but origin doesn’t seem to matter.

It appears that no LLM can get more than about a third of returns correct. Kimi K3 is on par with Sonnet 5. They are both very bad at doing your taxes.

I like these tests

In 6 months an LLM will get it to 80%

people will exclaim negatively “it was trained on the eval [to do this incredibly useful thing]”

meanwhile a problem is solved
