Abstract:

With the rapid iteration of artificial intelligence technology, model training has shifted from the stage of general-scale expansion to a new stage driven by industrial applications and supported by high-quality data. The type, quality and supply capacity of data directly determine the industry adaptability and practical effectiveness of models. Data demands vary across the full life cycle of large models, and there are still shortcomings in the supply of high-quality datasets for industrial scenarios. Based on this, the focus is placed on the full stages of large model pre-training, supervised fine-tuning, reinforcement alignment, and engineering application. This paper sorts out the data demands of each stage and the evolutionary trend from “scale-oriented” to “quality-oriented”. The evolving trends of data needs at each stage are analyzed, the disparities in high-quality data supply between international and domestic standards are compared, and the shortcomings of China’s utilization of public data, data openness, and annotation ecosystems are examined. Consequently, targeted measures are proposed to optimize data supply, aiming to break through the bottleneck of training data for large models and support the advancement of the artificial intelligence industry.
