“Today” columns compare the as-of value with the current record; “same” means no recorded change. Click any as-of value for the claim behind it (source, tier, valid from → to).
Only models with a context-length claim valid on that date are listed (sorted by context). Models without a dated claim are omitted rather than guessed.
Shareable: this URL reproduces the view. Per-entity: every entity page has a History tab with the same as-of reconstruction. What changed since? Diff 11 Sept 2026 → today. Methodology →
