How this list is built
Generated from the dataset on every refresh. Nobody picks the order by hand.
Every OpenAI model on the overall index, ordered by the LLMBenchmark Index, highest first. The index is our own 0 to 100 composite of our five skill indexes, the Artificial Analysis Intelligence Index and the LMArena text Elo, with a 90% margin.
