Clément Delangue posted that APIs from companies like Anthropic and OpenAI are treated differently from open weights because the three layers require distinct rules. He compared weights to raw steel. Replies from Gary Marcus, Helen Toner, Andreas Kirsch, and others noted agreement on regulating at the layer where risks appear, such as finished apps, and referenced analogies to car manufacturing and commodity standards. Delangue replied that the approach makes sense and thanked participants. The conversation centers on his clarification of the original post.
