AI_dev: Open Source GenAI & ML Summit Europe 2025

EVE (Earth Virtual Expert) is an open-source domain-specific large language model designed to democratize access to Earth Observation (EO) and Earth Science (ES) knowledge. Backed by the European Space Agency and developed by Pi School and Imperative Space, EVE bridges AI and EO through domain-adaptive pre-training, instruction tuning, and Retrieval-Augmented Generation. It supports multiple user groups—from scientists and students to journalists and decision-makers—by enabling factual, source-grounded, and explainable interactions with EO content. This talk outlines EVE’s training pipeline, data compliance approach, performance benchmarks, and open-source contributions, including models, datasets, and legal compliance guides. We'll also share lessons from human evaluations, infrastructure challenges, and our roadmap toward an EO digital assistant.
