Two European models on Workers AI
As part of its Birthday Week, Cloudflare announced it is adding two European open models to its Workers AI platform. Both were built by public universities and research institutions, and access requests are open starting today.
EuroLLM: all 24 official EU languages
EuroLLM supports 35 languages, including all 24 official EU languages, many of which are underserved by existing open models. Developed with support from Horizon Europe, the European Research Council and EuroHPC, it was trained on the MareNostrum 5 supercomputer. According to the consortium, it outperforms similar-sized models on EU multilingual benchmarks and machine translation.
Apertus: Switzerland's fully open model
Apertus (Latin for "open") is Switzerland's first large-scale, fully open, multilingual language model. It was trained on more than 15 trillion tokens across more than 1,500 languages, with 40% of training data in languages other than English. It was developed by ETH Zurich, EPFL and the Swiss National Supercomputing Centre (CSCS). Its architecture, weights, training data and methods are all published.
Why it matters
Cloudflare frames the move around the argument that AI sovereignty is not zero-sum. According to the company, open models prevent a country or organization from depending on a single provider. Cloudflare is also launching hands-on workshops for government cyber agencies and critical infrastructure operators to build AI defenses that work with any model; the first runs in Singapore in October.
