What is Aria
Aria is the world's first open-source multimodal native Mixture of Experts (MoE) model launched by the Rhymes AI team, capable of understanding and processing multiple input modalities such as text, code, images, and video. The model demonstrates best-in-class performance on multimodal and language tasks, competing with proprietary models while remaining lightweight and fast. Aria has a long context window capability of 64K tokens, enabling efficient processing of complex long video and document data. The model weights, codebase, and technical report have all been open-sourced. Aria's innovative architecture and training methods support developers and researchers in exploring new possibilities in the field of multimodal AI.
Aria's Main Features
- Multimodal Understanding: Simultaneously processes and understands multiple types of data such as text, code, images, and video.
- High-Performance Task Processing: Demonstrates excellent performance in multimodal tasks, language understanding, and coding tasks.
- Long Context Processing Capability: Has a long context window of 64K tokens, effectively processing long videos and long documents.
- Open-Source Extensibility: With the model weights and codebase open-sourced, Aria can be widely adopted and further developed.
Aria's Technical Principles
- Mixture of Experts (MoE): Based on a fine-grained MoE architecture, each text token activates a large number of parameters, achieving efficient parameter utilization and computational efficiency.
- Vision Encoder: A lightweight vision encoder is designed to process visual inputs of different lengths, sizes, and aspect ratios, encoding visual information into tokens that the model can understand.
- Four-Stage Training Pipeline: Includes language pre-training, multimodal pre-training, long context pre-training, and multimodal post-training, progressively enhancing the model's capabilities on different modal tasks.
- Expert Parallelism and Data Parallelism: During training, expert parallelism and ZeRO-1 data parallelism techniques optimize the model's performance and training efficiency.
