Introduction
In the rapidly evolving landscape of natural language processing (NLP), the ability to effectively handle diverse languages has become a crucial frontier. Traditional NLP models often struggle to accommodate the nuances and complexities inherent in multilingual communication, hindering their widespread adoption. However, a new solution has emerged from the pioneering work of Cohere For AI – the Aya-23 family of multilingual language models.
Aya-23: Bridging the Multilingual Gap
Today, we launch Aya 23, a state-of-art multilingual 8B and 35B open weights release.

Cohere For AI, the non-profit research arm of the Canadian enterprise AI startup Cohere, has unveiled the Aya-23 models – a cutting-edge series of multilingual large language models (LLMs) that are poised to revolutionize the field of NLP. Aya-23 builds upon the success of the earlier Aya-101 model, which covered an impressive 101 languages, but with a strategic shift in focus.
Aya-23-8B: Efficiency and Accessibility
The Aya-23-8B model, featuring 8 billion parameters, is designed to strike a balance between performance and accessibility. By optimizing the model’s architecture and leveraging advanced techniques like grouped query attention and rotational positional embeddings, the Aya-23-8B delivers state-of-the-art multilingual capabilities without the need for extensive computational resources. This makes it an ideal choice for researchers and developers working with more modest hardware setups.
Aya-23-35B: Unparalleled Linguistic Prowess
For those with the computational power to harness its full potential, the Aya-23-35B model, boasting an impressive 35 billion parameters, offers unparalleled linguistic prowess. Building upon the foundation of Cohere’s Command R model, the Aya-23-35B incorporates a range of enhancements that elevate its performance in complex multilingual tasks, including natural language understanding, summarization, and translation.
Aya’s Multilingual Ecosystem
The Aya-23 models are not mere standalone achievements; they are the culmination of Cohere For AI’s broader Aya initiative – a collaborative effort involving over 3,000 independent researchers from 119 countries. This global initiative has yielded a rich ecosystem of resources, including the Aya Collection, a massive multilingual dataset of 513 million prompts and completions spanning 114 languages.
The Aya Collection: Fueling Multilingual Advancement
The Aya Collection serves as the foundation for the Aya-23 models, providing a diverse and high-quality training dataset that enables the models to excel across a wide range of languages. By leveraging this extensive resource, the Aya-23 models demonstrate superior performance compared to other widely used multilingual models, such as Gemma, Mistral, and Mixtral.
Aya-101: Laying the Groundwork
While the Aya-23 models represent the latest iteration of Cohere For AI’s multilingual efforts, the groundbreaking Aya-101 model should not be overlooked. Aya-101, released in February 2024, was a pioneering achievement in its own right, covering an unprecedented 101 languages and setting new benchmarks in massively multilingual language modeling.
Aya-23’s Performance Advantages
The Aya-23 models have undergone rigorous evaluation, showcasing their remarkable capabilities in multilingual tasks. Compared to their predecessor, Aya-101, the Aya-23 models demonstrate significant improvements across a range of discriminative and generative tasks, with the 8-billion parameter version achieving best-in-class multilingual performance.
Outperforming the Competition
When benchmarked against other widely used open-source models, such as Gemma, Mistral, and Mixtral, the Aya-23 models consistently outperform their counterparts. The researchers report improvements of up to 14% in discriminative tasks, 20% in generative tasks, and a remarkable 41.6% increase in multilingual mathematical reasoning compared to Aya-101.
Consistent Quality Across Languages
One of the standout features of the Aya-23 models is their ability to maintain a high level of consistency and coherence in the text they generate, regardless of the target language. This is a crucial advantage for applications that require seamless multilingual support, such as translation services, content creation, and conversational agents.
Accessibility and Open-Source Commitment
Cohere For AI’s commitment to advancing multilingual AI research extends beyond the technical achievements of the Aya-23 models. The company has made a concerted effort to ensure that these powerful tools are accessible to a wide range of researchers and developers.
Open Weights Release
Cohere For AI has released the open weights for both the Aya-23-8B and Aya-23-35B models, empowering the research community to further explore, fine-tune, and build upon these state-of-the-art multilingual models. This open-source approach aligns with the company’s mission to democratize access to cutting-edge AI technology.
Empowering the Research Community
By providing the open weights, Cohere For AI aims to inspire and empower researchers and practitioners to push the boundaries of multilingual AI. This gesture not only facilitates the advancement of the field but also fosters a collaborative spirit, where the global research community can collectively work towards addressing the challenges of language barriers in technology.
The Aya Initiative: A Paradigm Shift in Multilingual AI
The Aya-23 models are not merely the latest products of Cohere For AI’s research efforts; they are part of a broader initiative that is reshaping the landscape of multilingual AI. The Aya project, which has garnered the participation of over 3,000 independent researchers from 119 countries, represents a paradigm shift in how the machine learning community approaches the challenges of multilingual language modeling.
Democratizing Multilingual AI
By leveraging the diverse perspectives and expertise of researchers from around the world, the Aya initiative has created a rich tapestry of knowledge and resources that are now accessible to the broader community. This collaborative approach has enabled the development of models like Aya-23, which cater to the linguistic needs of nearly half the global population.
Empowering Underserved Languages
“In our evaluation, we focus on 23 languages that are covered by the new Aya model family. These 23 languages are: Arabic, Chinese (simplified & traditional), Czech, Dutch, English, French, German, Greek, Hebrew, Hindi, Indonesian, Italian, Japanese, Korean, Persian, Polish, Portuguese, Romanian, Russian, Spanish, Turkish, Ukrainian and Vietnamese.”
you can read in Cohere’s paper.
One of the key drivers behind the Aya initiative is the recognition that the field of AI has historically been dominated by a handful of languages, leaving many others underrepresented and underserved. The Aya-23 models, with their support for 23 languages, including rare and low-resource ones, represent a significant step towards addressing this imbalance and ensuring that more languages are treated as first-class citizens in the rapidly evolving world of generative AI.
The Future of Multilingual AI: Aya-23 and Beyond
The introduction of the Aya-23 models marks a pivotal moment in the ongoing journey of multilingual AI research and development. As the field continues to evolve, the Aya-23 models and the broader Aya initiative stand as beacons of progress, inspiring researchers and practitioners to push the boundaries of what is possible in the realm of natural language processing.
Driving Continuous Improvement
Cohere For AI’s commitment to the Aya project ensures that the journey of multilingual AI advancement will not end with the Aya-23 models. The company’s continued investment in research and development, coupled with the collaborative efforts of the global Aya community, will undoubtedly lead to further refinements, enhancements, and breakthroughs in the years to come.
