Product Description

Fuyu is a multimodal model developed by Adept AI specifically designed for digital agents. Its unique architecture completely eliminates the use of an image encoder (ViT), instead directly projecting image patches linearly into the first layer of the Transformer, achieving a pure decoder-only architecture. This simplified design allows the model to support arbitrary image resolutions, with response times for large images under 100 milliseconds. Fuyu-Heavy even outperforms Gemini Pro in UI understanding.

Core Features/Characteristics

• No Image Encoder Architecture: Pure Decoder-only Transformer, images directly projected linearly
• Arbitrary Resolution Support: Not limited by fixed image sizes
• Leading UI Understanding: Surpasses Gemini Pro on MMMU benchmark, excels in UI comprehension
• Ultra-Fast Response: Processes large images in under 100 milliseconds
• 16K Context: Supports a context window of 16,000 tokens
• Chart and Graphic Understanding: Accurately answers questions about charts and data visualizations
• Fine-Grained Localization: Identifies fine-grained positions on screen images
• Long Conversation Capability: Supports coherent long-form human dialogues

Business Model

• Fuyu-8B Open Source: CC-BY-NC license (non-commercial)
• Fuyu-Heavy Not Open Source: Only available through Adept products
• Adept Acquired by Amazon: Team joined Amazon in 2024

Target Users

• Digital agent and RPA developers
• UI automation tool developers
• Applications requiring real-time image processing
• Screen understanding and assistive technology developers
• Multimodal AI architecture researchers

Competitive Advantages

• Simplified and efficient architecture without ViT, supports arbitrary resolutions
• Leading UI understanding among models of similar scale
• Ultra-fast 100ms response time
• Specifically designed for digital agents, naturally fits agent scenarios
• Architectural innovation has profound impact on subsequent models

Competitive Disadvantages

• Fuyu-8B is non-commercial licensed

Relationship with OpenClaw Ecosystem

Fuyu's ViT-free architecture and UI understanding capabilities are highly valuable for OpenClaw's digital agent scenarios. Its support for arbitrary resolutions and 100ms response time enable OpenClaw's AI agents to quickly understand screenshots of various sizes. Fuyu's architectural concept (directly projecting image patches) also provides technical reference for OpenClaw in building lightweight multimodal agents. Note the CC-BY-NC license restrictions; commercial use requires seeking alternatives.
