Other Aya models
Aya Vision is a research model advancing in multilingual multimodal AI through innovative synthetic data generation, cross-modal model merging, and a comprehensive benchmark suite. It achieves state-of-the-art performance across 23 languages, surpassing larger models while efficiently addressing data scarcity and catastrophic forgetting by reducing computational overhead up to 40% via optimized training techniques.
Aya Expanse redefines multilingual AI as a research model mastering 101 languages through innovative instruction tuning and cross-lingual transfer techniques. By combining a curated open-source dataset with compute-efficient pretraining, it achieves unparalleled performance across low- and high-resource languages while reducing infrastructure costs by up to 30%—setting a new benchmark for scalable, inclusive language modeling.
Aya 101 is a groundbreaking research model delivering instruction-tuned proficiency across 101 languages, developed through a global collaborative effort involving 3,000+ researchers. As the cornerstone of Cohere Labs’ multilingual initiative, it establishes a new standard for inclusive AI by achieving state-of-the-art performance on diverse benchmarks while maintaining efficiency across low- and high-resource languages—all released as an open-source framework to accelerate equitable language technology worldwide.
Aya began as the largest open science collaboration in ML, bringing together a community of researchers from around the world to create a powerful foundation for future innovation. This initial effort laid the groundwork for subsequent research initiatives and the development of additional models, pushing the boundaries of what is possible and expanding the world that AI sees.
