• Notably, Claude Opus 4.1 and 4—the most recently released and most capable models of those that we test—perform the best in our experiments, suggesting that introspective capabilities may emerge alongside other improvements to language models.quote0.725
  Key finding about the relationship between capability and introspection.
• In every case, the process is straightforward, simple, and above all free: it allows the reality of the situation, the human needs, human joys, to find expression.claim0.724
