For about 20 years, chess fans would hold "centaur" tournaments. In those events, the best chess computers, who routinely trounced human grandmasters, teamed up with those same best-in-the-world humans and proceeded to wipe both humans and computers off the board. Nicholas is describing in detail how he pairs up with LLMs to get a similar result in programming and research.
Sobering thought: centaur tournaments at the top level are no more. That's because the computers got so good that the human half of the beast no longer added any meaningful value.
