How to Use a VLM to Control a PC

A vision language model (VLM) like Qwen 3.5 enables PCs to be controlled through visual inputs and plain-language instructions, effectively automating tasks without needing an API or predefined scripts. This approach involves capturing a screenshot, sending it to the VLM with a command such as "click the train button," and executing the action based on the model's response, which is typically a screen coordinate. This method allows for the automation of repetitive tasks, testing, and quality assurance across various applications, even those not initially designed for automation. The recent integration of vision, language, and coding capabilities into a single VLM, as demonstrated in a Roboflow webinar by engineer Matvei Popov, highlights the model's ability to manage complex tasks like starting a model training job without human intervention, showcasing its potential for broader applications beyond desktop environments.
