AI Atlas

The temporal knowledge graph of the AI ecosystem. Every number links back to its source, tier and observation time; history is never discarded; conflicts are shown, never averaged.

Category (lane)Event typeFilters the loaded events (the API has no type filter on /timeline).OrganizationFamilyOrganization and family scope the timeline to that entity (one at a time).Min importanceInclude historical backfillBackfill = history imported when a source is first crawled (release dates, past prices). Off by default so the timeline shows what AI Atlas observed happening; on, it shows the reconstructed history.

Semantics

occurred_at: coalesce(effective_at, observed_at) — when the change happened (effective date when a source states it)
observed_at: when AI Atlas first saw the change
recorded_at: when the row was written
is_backfill: true for history imported when a source is first crawled (never shown as 'today' in feeds)
group_key: one release / announcement seen through several documents shares a group_key

Times are UTC. Per-entity history: open any entity's History tab. Compare two dates in Diff; see the atlas as of a date in the Time machine.
