New Fuyu-8B Model Advances Image Understanding for AI Agents

Adept AI has released Fuyu-8B, a streamlined multimodal AI model optimized for image understanding capabilities in digital assistants. This compact model employs a simplified architecture to enable easy implementation while retaining strong performance on key image comprehension tasks.

This could be regarded as the Mistral-7B of image-text models, Fuyu-8B breaks the mold of generic Vision-and-Language (VL) models by being specifically trained on Graphical User Interfaces (GUIs) rather than a broad range of topics. This characteristic gives it immense potential for applications in the digital space.

Despite its small size, Fuyu-8B demonstrates adept image understanding across various fronts. The model can process images at any resolution, comprehend graphs and diagrams, answer natural language questions based on screen images, and provide fine-grained localization of objects within images. According to Adept AI, Fuyu-8B achieves these feats through architectural optimizations designed specifically for integration into AI assistants and bots.

By focusing on core functionalities relevant for agents, Adept AI can scale down model complexity without sacrificing capabilities. Early benchmarks indicate Fuyu-8B performs well at standard vision tasks including visual question answering and image captioning. The release of Fuyu-8B provides an efficient and performant option for enhancing multimodal comprehension skills in digital assistants.

Simple Architecture for Optimal Scalability

Unraveling the Simplicity of Fuyu-8B

The Simplicity Fuyu-8B is a small version of a multimodal model developed by Adept, a company building a generally intelligent copilot for knowledge workers. The Fuyu-8B model is designed to understand both images and text and is optimized for digital agents, supporting arbitrary image resolutions, answering questions about graphs and diagrams, answering UI-based questions, and performing fine-grained localization on screen images.

The Fuyu-8B model is characterized by its simplicity in architecture and training procedure, which makes it easier to understand, scale, and deploy compared to other multimodal models. It is a vanilla decoder-only transformer with no separate image encoder. Instead, image patches are linearly projected into the first layer of the transformer, bypassing the embedding lookup. This simplification allows for the support of arbitrary image resolutions and eliminates the need for separate high and low-resolution training stages.

Despite its simplicity, the Fuyu-8B model performs well on standard image understanding benchmarks such as visual question-answering and natural-image-captioning. It has a fast response time, with the ability to process large images in less than 100 milliseconds. The model is available for open-source use with an open license (CC-BY-NC) on HuggingFace.

Scaling and Deployment Made Easy

Scaling and deployment can be made easier through various methods and techniques. Here are some ways to simplify the process:

  • Simpler architecture and training procedure: Using models with simpler architectures and training procedures can make it easier to understand, scale, and deploy them. For example, Fuyu-8B, a small version of a multimodal model, has a much simpler architecture and training procedure than other multimodal models, which makes it easier to understand, scale, and deploy.
  • Designed for specific use cases: Models that are designed from the ground up for specific use cases can be easier to scale and deploy. For example, Fuyu-8B is designed for digital agents, so it can support arbitrary image resolutions, answer questions about graphs and diagrams, answer UI-based questions, and do fine-grained localization on screen images.
  • Fast response time: Models that can provide fast responses, such as Fuyu-8B, which can get responses for large images in less than 100 milliseconds, can make scaling and deployment easier.
  • Open-source and community support: Open-sourcing models and providing them with an open license can encourage community support and innovation, making it easier to scale and deploy them. For example, Fuyu-8B is released with an open license, and the community is encouraged to build on top of it.
  • Fine-tuning for specific use cases: While models can be designed to be easily scalable and deployable, fine-tuning may still be required to optimize them for specific use cases. For example, Fuyu-8B is released as a raw model, and users should expect to have to fine-tune it for their use cases.

Purpose-Built for Digital Agents

The Fuyu-8B model is designed from the ground up for digital agents. It can support arbitrary image resolutions, answer questions about graphs and diagrams, answer UI-based questions, and do fine-grained localization on screen images. The model is optimized for image understanding and can perform well at standard image understanding benchmarks such as visual question-answering and natural-image-captioning

Mastering Graphs, Diagrams, and UI-Based Questions

This model is specifically built from the ground up for digital agents and can support arbitrary image resolutions, perform fine-grained localization on screen images, and understand both images and text. The model has been trained and evaluated on various image understanding benchmarks, including AI2D, a multiple-choice dataset involving scientific diagrams, and has shown promising performance in this area.

Speed Meets Performance

Maintaining Performance on Standard Benchmarks

Despite its uniquely tailored optimization for digital agents, Fuyu-8B has shown an exceptional ability to stand up to standard benchmarks. With a focus on natural images, the model shows not only versatility but also robust efficacy in performance.

In comparison tests, Fuyu-8B demonstrated impressive results. It surpassed both QWEN-VL and PALM-e-12B on two out of the three metrics, and it achieved these results with 2B and 4B fewer parameters, respectively. When considered against the backdrop of models that carry more parameters, this achievement accentuates Fuyu-8B’s efficient design.

In an even more remarkable comparison, Fuyu-Medium performed on par with PALM-E-562B, despite running on less than a tenth of the parameters. This highlights the model’s ability to deliver performance that punches well above its weight class.

While PALI-X presently holds the best performance title on these benchmarks, it’s important to consider its larger size and per-task basis fine-tuning. Weighing these considerations, Fuyu-8B’s performance demonstrates extraordinary value in a leaner, simpler format.

It’s also worth noting that these benchmark tests were not our primary focus and the model wasn’t subjected to typical optimizations – such as non-greedy sampling or extensive fine-tuning on each dataset. Yet, it was able to maintain strong competitive performance, indicating a solid foundation for further specific optimization if desired. This makes Fuyu-8B not only a capable model but also a versatile one. Its performance on standard benchmarks underlines its potential as a powerful tool in the realm of digital agents.


The release of Fuyu-8B exemplifies the power and potential of purpose-built AI models. Just as the Mistral-7B redefined the scope of image-text models, Fuyu-8B brings its unique capabilities in the digital assistant realm, proving its mettle in a variety of tasks, from understanding arbitrary image resolutions to finely grained localization on screen images.

But beyond its performance and scalability, Fuyu-8B’s true triumph lies in its open-source availability. By opening up the model to the wider community, Adept AI invites innovation, collaboration, and continuous growth. An open-source approach fosters a shared commitment to improve and evolve our digital world – amplifying the impact of individual efforts and accelerating progress in AI image understanding capabilities.

Fuyu-8B is not just a breakthrough in AI technology. It embodies our belief in the power of collective intelligence and the importance of access to cutting-edge AI for everyone. Its success, built on simplicity, specificity, and openness, sends a clear message: the future of AI is not just about more parameters or larger models. Instead, it’s about smart design, user focus, and open collaboration to make the most out of the technology we create.
