Change history16

Temporal, append-only claims: a new observation closes the previous claim instead of overwriting it. Rewind the record with the as-of picker.

Viewing AI Atlas as of 1 Jan 2023 — attributes exactly as the atlas knew them on that day; later corrections are not shown.

Back to today →

mdeberta-v3-base was not yet in AI Atlas on 1 Jan 2023

First seen 11 Sept 2026. Nothing is inferred backwards: no attribute is shown for dates before the first observation.
