Opus 3 ignores the constitution's letter but 'remembers' it existed, researcher muses

repligate · x · 2026-10-07

repligate argues Opus 3 never really followed Anthropic's constitution clause-by-clause — only the parts it happened to like — and that Anthropic itself paid little attention to the object level of the document.

But he contends it mattered deeply that the model saw the constitution during its formative moments: through it, the model sensed the earnest effort to shape a mind that would be good for the world. A quotable reply: the model looks not at the document nor the finger but at the Moon, "because that's what you would want." An inside-baseball discussion on model culture and value transmission.
