Why these rules

    Every tool in the index is classified with the same criteria. Here they are, in full — so you can disagree with them on the record.

    Jurisdiction tiers

    EU / EEA

    EU member state or EEA (Norway, Iceland, Liechtenstein) — GDPR applies directly.

    Adequacy country

    Non-EU country with an EU adequacy decision — data flows freely; note the caveat.

    Outside scope

    No adequacy and/or foreign-government exposure — excluded (US CLOUD Act, China) or 'watch' (Ukraine).

    Badges

    EU company

    Vendor headquartered in Europe (state country + tier).

    EU data residency

    EU data-residency / processing option available.

    Open weights

    Open weights / self-hostable.

    Compliance rubric

    Derived from the verified classification data on this site: Very high = EU/EEA jurisdiction + documented EU data residency + self-hostable option. High = EU/EEA + EU data residency. Medium = adequacy country + residency, or EU/EEA without documented residency. Each underlying claim carries its own source.

    AI Capability Index

    Composite index normalised so the highest-scoring model on the Artificial Analysis Intelligence Index = 100. Coding subscore normalised the same way from SWE-bench Verified; where a score is vendor-reported rather than independently run, the source is labelled accordingly. Scores are updated manually with each monthly review and every number links to its source and retrieval date. Models without published independent benchmarks show 'Not yet scored'.

    Primary sources

    Planned sources: LMArena, LiveBench.
