Anthropic Publishes Claude Constitution for Training

Anthropic published the 80+ page 'constitution' it uses to train Claude, the company's large language model, and released it under a CC0 license. The document details values, behavioral guidelines, and trade-off advice, and Anthropic describes it as the 'final authority' shaping Claude's training and outputs. The release prompted interviews with primary author Amanda Askell and a user Q&A video, highlighting the company's transparency effort.
