Ant Group Digital Technologies has officially launched its decision model LingDT-Decision-1.0, available in 4B and 27B parameter versions on the company's DTMaaS platform. Designed for rapid decision-making tasks, the model shifts from a "generate first, then parse" approach to "directly judging among limited options," reducing token consumption by over 90% and improving response speed by up to 10x in real business tests across customer service, risk control, and finance. In intelligent customer service scenarios, risk identification accuracy rose from 76% to 89%, while hallucination recall in financial scenarios increased from 44% to 70%. LingDT-Decision-1.0 is the world's first decision model featuring native multi-select and sequential decision-making (DAG) capabilities, enabling it to identify multiple requests simultaneously and complete multi-step decisions based on task dependencies. In evaluations across 23 mainstream open-source benchmarks, the 27B version ranked first in overall score, surpassing Microsoft-Decision-1, Jev 1.13.0, and Fastino/GLiDE models of comparable parameter scale.
