**What it does not test.** It does not establish that JUPITER has yet reached full exascale performance, which needs around 207 more petaflops.

**How this item counts.** This item is dated before the index starts on 1 January 2026, so it does not count in the [European Sovereignty Index](https://sovereigntymonitor.eu/sovereignty-index/).

**How this item was made.** Drafted by an AI system (Claude (Anthropic)) from the source cited above; read and approved by the editor on 2026-10-20\. [How the record is made](https://sovereigntymonitor.eu/method/#how-the-record-is-made)
