Two European open models (EuroLLM: 35 languages; Apertus: 1,500 languages) now available via Workers AI for sovereign, multi-language inference without vendor lock-in.
Summary
Developers can now build multilingual applications on non-US infrastructure without frontier model dependencies. Apertus notably supports rare/regional languages (Romansh, Swiss German, low-resource Asian/African languages) where closed models underperform, unlocking new use cases for underserved regions.

Implementation verdict
Replaces dependency on closed frontier models for EU/multilingual workloads. Requires requesting access via Workers AI platform; no code changes if already using Workers AI inference APIs. Ready now—both models published with full weights/training data. Apertus explicitly designed for GDPR/EU AI Act compliance, reducing legal friction in regulated environments.
