AI that sees, understands words, and can perform actions, often controlling robots.
Vision Language Action models, or VLAs, are a type of artificial intelligence that combines several abilities. They can "see" and interpret images or video, understand spoken or written commands, and then translate that understanding into physical actions.
Think of a robot assistant. You could show it a mess on the floor and say, "Please clean that up." A VLA would process the image of the mess, understand your instruction, and then direct the robot's arms and tools to pick up the debris. This allows AI to interact with and manipulate the physical world.
Vision Language Action (VLA) models integrate perception, language understanding, and action generation. They process visual inputs (images, video) and natural language commands to produce a sequence of actions, typically for robotic control. This involves mapping multimodal inputs to a policy that outputs motor commands or high-level task instructions.
These models are crucial for embodied AI, enabling robots to perform complex tasks in unstructured environments. Tradeoffs often involve the complexity of visual scenes, the nuance of language instructions, and the precision required for physical actions. Current research focuses on improving generalization across tasks and environments, and enabling more sophisticated interaction with tools and objects.
Recent advancements in large multimodal models have enabled more sophisticated integration of vision, language, and action. Google's Gemini Robotics announcements highlight the push to apply these VLAs to real-world robotic tasks, showing progress in embodied reasoning and instrument reading.

The concept of integrating vision, language, and action has been a long-standing goal in AI and robotics research. The specific term "Vision Language Action models" has emerged more recently with the rise of powerful foundation models capable of handling these multiple modalities.
While direct VLA interaction might require specialized hardware, you can explore similar concepts. Try using a multimodal AI assistant like Google Gemini or ChatGPT with image input and ask it to describe the actions needed to achieve a goal, like "What steps should I take to assemble this furniture based on the picture?" This demonstrates the vision-language understanding part of a VLA.

Questions people ask
- What is the main difference between a VLA and a VLM?
- VLAs can generate actions for physical tasks based on vision and language, while VLMs primarily focus on understanding and describing visual content using language.
- Are VLAs only used for robots?
- While robots are a primary application, the principles of VLAs could potentially be applied to other systems that need to perceive, understand instructions, and then perform actions in a physical or simulated environment.
