  • Abstract:
  • Modern artificial intelligence applications rely heavily on large-scale generative language models (LLMs), however these models can still suffer from representational distortions, hallucinations, and systemic biases, which make them unreliable, unsafe, and untrustworthy. In this paper, a conceptual-theoretical framework combining mechanisms of bias reduction, hallucination detection architecture, and safe-generation protocol is suggested to fit modern LLMs. Based on the progress in the parameter of model alignment, dataset curation, uncertainty quantification, retrieval-augmented generation, reinforcement learning based on human feedback, and constraint-based decoding the paper posits hallucination mitigation as a design priority that is deeply embedded into the training pipeline. It builds on the idea that bias and hallucination are scale-dependent emergent properties of model design, dynamical strategies of statistical learning, and distributional discrepancies, so to avert them, multi-level interventions such as pre-training data control to post-processing verification cycles will be necessary. Suggestions are made on conceptual indicators that can be used to assess model integrity, factual consistency, contextual grounding and fairness strength.
