Publication number: 20250086402Abstract: Methods, systems, apparatuses, devices, and computer program products are described. A flow generation service may receive a natural language input that indicates instructions for automating a task according to a first process flow. Using a large language model (LLM), the flow generation service may decompose the natural language input into a set of elements (e.g., logical actions) and connectors, where the LLM may be trained on first metadata corresponding to a second process flow that is created manually by a user. In addition, using the LLM, the flow generation service may generate second metadata corresponding to each of the set of elements based on decomposing the natural language input. The flow generation service may sequence and merge the set of elements to generate the first process flow. In some examples, the flow generation service may send, for display to a user interface of a user device, the first process flow.Type: ApplicationFiled: January 17, 2024Publication date: March 13, 2025Inventors: Ran Xu, Zeyuan Chen, Yihao Feng, Krithika Ramakrishnan, Congying Xia, Juan Carlos Niebles Duque, Vetter Serdikova, Huan Wang, Yuxi Zhang, Kexin Xie, Donglin Hu, Bo Wang, Ajaay Ravi, Matthew David Trepina, Sam Bailey, Abhishek Das, Yuliya Feldman, Pawan Agarwal
