# Claude Opus 5.5 · medium original cycling animation

The original upper-left panel says medium - one prompt + use skills, matching the body’s medium label. The author uses pi and custom skills. Medium also received use the skills; no separate unnudged version is published, so none is invented. Four actual outputs count separately; the original medium represents the timeline, not the most polished later refinement. Model labels and attribution remain source-reported, not independently authenticated. The date is verifiable public posting, not inferred generation. Author costs, times and opinions are not museum scores or capability findings.
