The passage around this formula
…of the weights , the harness , the sampling temperature T , the number of samples k and how they are aggregated, the prompt template , the date t a snapshot was queried, plus sampling noise . A citation that fixes and leaves the other five free has not specified a comparable quantity. OpenAI’s own simple-evals table makes the same point from a different angle: rows the lab ran itself under a disclosed zero-shot chain-of-thought protocol sit beside rows for…
