Yi: Open Foundation Models by 01.AI Revealed


Core Concepts
The author introduces the Yi model family, highlighting its strong multi-dimensional capabilities achieved through data quality and engineering efforts. The performance of Yi models is attributed to scalable super-computing infrastructure and classical transformer architecture.
Abstract
The Yi model family, developed by 01.AI, showcases advanced language and multimodal capabilities through various models like chat models, vision-language models, and more. The models achieve high performance on benchmarks like MMLU and demonstrate strong human preference rates. Data quality plays a crucial role in the success of Yi models, with extensive data processing and cleaning pipelines ensuring high-quality training data. Pretraining involves constructing a massive corpus of English and Chinese tokens, while finetuning focuses on meticulously curated instruction datasets. The architecture of Yi models follows standard Transformer implementations with unique modifications for improved performance. The capability extension includes long context modeling, vision-language adaptation, and depth upscaling to enhance model performance further.
Stats
Our base models achieve strong performance on benchmarks like MMLU. For pretraining, we construct 3.1 trillion tokens of English and Chinese corpora. Finetuning involves polishing a small-scale instruction dataset over multiple iterations. The Yi model uses byte-pair encoding (BPE) with a vocabulary size of 64,000. Model configurations include hidden sizes, Q-heads, KV-heads, layers, pretrain sequence length, and max learning rates.

Deeper Inquiries

How does the scalability of the Yi model family compare to other AI models in the industry?

The scalability of the Yi model family is quite impressive when compared to other AI models in the industry. The Yi model series, particularly the 6B and 34B language models, have been pretrained on a massive amount of data totaling 3.1 trillion tokens in English and Chinese corpora. This extensive pretraining data allows for strong multi-dimensional capabilities and performance across various benchmarks like MMLU. In terms of model size, Yi-34B stands out as a large-scale language model that strikes a balance between complexity and feasibility for inference on consumer-grade hardware like RTX 4090 GPUs with limited memory capacity. The choice of using a smaller but still powerful model like Yi-34B showcases an optimal performance-cost balance compared to larger models like Falcon-180B. Furthermore, the scalability of the Yi models is evident in their ability to continually improve through lightweight continual pretraining methods that extend context length up to 200K tokens. This approach demonstrates an understanding of how scaling up both data quality and quantity can lead to stronger frontier models. Overall, the scalability of the Yi model family sets it apart from other AI models by showcasing advancements not only in size but also in performance across various tasks and benchmarks.
