Compare Aya vs. Llama 2 vs. LongLLaMA

Aya represents a cutting-edge, open-source generative language model that boasts support for 101 languages, significantly surpassing the language capabilities of current open-source counterparts. By facilitating access to advanced language processing for a diverse array of languages and cultures that are often overlooked, Aya empowers researchers to explore the full potential of generative language models. In addition to the Aya model, we are releasing the largest dataset for multilingual instruction fine-tuning ever created, which includes 513 million entries across 114 languages. This extensive dataset features unique annotations provided by native and fluent speakers worldwide, thereby enhancing the ability of AI to cater to a wide range of global communities that have historically had limited access to such technology. Furthermore, the initiative aims to bridge the gap in AI accessibility, ensuring that even the most underserved languages receive the attention they deserve in the digital landscape.

Introducing the next iteration of our open-source large language model, this version features model weights along with initial code for the pretrained and fine-tuned Llama language models, which span from 7 billion to 70 billion parameters. The Llama 2 pretrained models have been developed using an impressive 2 trillion tokens and offer double the context length compared to their predecessor, Llama 1. Furthermore, the fine-tuned models have been enhanced through the analysis of over 1 million human annotations. Llama 2 demonstrates superior performance against various other open-source language models across multiple external benchmarks, excelling in areas such as reasoning, coding capabilities, proficiency, and knowledge assessments. For its training, Llama 2 utilized publicly accessible online data sources, while the fine-tuned variant, Llama-2-chat, incorporates publicly available instruction datasets along with the aforementioned extensive human annotations. Our initiative enjoys strong support from a diverse array of global stakeholders who are enthusiastic about our open approach to AI, including companies that have provided valuable early feedback and are eager to collaborate using Llama 2. The excitement surrounding Llama 2 signifies a pivotal shift in how AI can be developed and utilized collectively.

This repository showcases the research preview of LongLLaMA, an advanced large language model that can manage extensive contexts of up to 256,000 tokens or potentially more. LongLLaMA is developed on the OpenLLaMA framework and has been fine-tuned utilizing the Focused Transformer (FoT) technique. The underlying code for LongLLaMA is derived from Code Llama. We are releasing a smaller 3B base variant of the LongLLaMA model, which is not instruction-tuned, under an open license (Apache 2.0), along with inference code that accommodates longer contexts available on Hugging Face. This model's weights can seamlessly replace LLaMA in existing systems designed for shorter contexts, specifically those handling up to 2048 tokens. Furthermore, we include evaluation results along with comparisons to the original OpenLLaMA models, thereby providing a comprehensive overview of LongLLaMA's capabilities in the realm of long-context processing.
