Bridging the Know-Act Gap via Task-Level Autoregressive Reasoning

📰 ArXiv cs.AI

Researchers propose task-level autoregressive reasoning to bridge the know-act gap in LLMs, where models can recognize flawed inputs but fail to reflect this in generative responses

advanced Published 25 Mar 2026
Action Steps
  1. Identify the know-act gap in LLMs, where models can recognize flawed inputs but fail to reflect this in generative responses
  2. Develop task-level autoregressive reasoning to bridge this gap
  3. Evaluate the effectiveness of this approach in various settings, such as math word problems or question answering
  4. Refine and fine-tune the approach to improve the performance of LLMs
Who Needs to Know This

AI engineers and ML researchers can benefit from this research as it provides a new approach to improve the performance of LLMs in generating valid and accurate responses, and product managers can apply this to develop more reliable AI-powered products

Key Insight

💡 The know-act gap in LLMs can be addressed by developing task-level autoregressive reasoning, which enables models to reflect their recognition of flawed inputs in generative responses

Title: Bridging the Know-Act Gap via Task-Level Autoregressive Reasoning

Abstract:
arXiv:2603.22619v1 Announce Type: new Abstract: LLMs often generate seemingly valid answers to flawed or ill-posed inputs. This is not due to missing knowledge: under discriminative prompting, the same models can mostly identify such issues, yet fail to reflect this in standard generative responses. This reveals a fundamental know-act gap between discriminative recognition and generative behavior. Prior work largely characterizes this issue in narrow settings, such as math word problems or quest
