Claude
4 reportsThe key evidence surrounding Claude comes from model architecture; training data and compute; and benchmark behavior. Conclusions concerning model architecture remain tied to real-world error analysis, documented evaluations, and transparent methods; any broad claim must allow for the fact that closed data, changing versions, and prompt sensitivity can make comparisons difficult.
