Even with the ongoing enhancements in the performance and cost-efficiency of large-scale models, three significant challenges continue to plague their practical implementation in business settings: the vague articulation of requirements, the indistinct delineation of model capabilities, and the complexities involved in dynamically adjusting to contextual changes. To tackle these issues head-on, Volcano Engine has rolled out the PromptPilot platform. This innovative solution leverages a systems engineering methodology that integrates "data-driven strategies with interactive collaboration" to cultivate three fundamental capabilities: guided exploration of requirements, automated refinement of prompts, and a closed-loop analysis of problematic cases. The platform presents a structured functional architecture that spans the entire spectrum of requirements, catering to a wide array of scenarios and ensuring compatibility across various models. Real-world application scenarios have shown that it can markedly boost efficiency and diminish the hurdles faced by both business professionals and AI developers. Moving forward, Volcano Engine is poised to propel the platform's capabilities in multiple directions, nurturing an ecosystem conducive to the widespread adoption of large-scale model applications.
