Nathan Lambert(@natolambert):With the external hack of OpenAI via Claude, closed models continue to be the tip of the iceberg on AI risks, not open models. They have been 1) easier to get started with, 2) more capable & 3) shipped w/ leaky safeguards. Finetuning open models to specific attacks is harder.
