eustella Launches Version 1.5, Boosts Open-Weight AI to Top
Vienna-based startup eustella has released version 1.5 of its AI platform, featuring improved open-weight models through proprietary post-training. The new model, based on Qwen 3.8 27B, outperforms the base model by an average of 5 points across 14 benchmarks, and rivals leading US models in coding and long-document comprehension. Notably, eustella claims a 16-fold reduction in political bias compared to Chinese base models, reducing responses reflecting Chinese government narratives from 30.4% to 1.9%. The company also introduces team and enterprise plans at €20 and €80 per user per month, respectively, offering a dedicated retrieval system, organization-wide search, and central administration. eustella now serves over 22,000 users and has granted early API access to 25 partners. The development is supported by the AI Factory Austria, part of the EuroHPC Joint Undertaking, underscoring European AI sovereignty efforts.
