anthropic/claude-opus-4-0 · fresh source comparison run

The author explicitly calls this a fresh new pelican: a new same-day Opus 4 run, not a replacement for earlier Opus 4 works. Model attribution is source-reported, not independently authenticated. The date uses the response timestamp in the original log; the article publication date is recorded separately. Generation time is not independently authenticated. Original bytes archived without redrawing or improving.
