You may well ask, why did Google give this wonderful thing away freely? While big private research outfits have been criticized in the past for withholding their work, the trend over the last few years has been toward publishing. This is a prestige play and also a concession to the researchers themselves, who would rather their employer not hide their light under a bushel. There is likely an element of hubris to it as well: Having invented the tech, how could Google fail to best exploit it? The capabilities we see in ChatGPT and other large language models today did not immediately follow. It takes time to understand and take advantage of a new tool, and every major tech company got to work examining what the new era of AI might provide, and what it needed to do so.
