🧠FIDES is a training-free decoder that improves how language models handle conflicts between retrieved evidence and internal knowledge by applying selective, token-level corrections rather than uniform adjustments. The method achieves up to 92-94% context fidelity across multiple model scales, demonstrating that targeted intervention at critical decoding points outperforms existing contrastive decoding approaches.

🧠A comprehensive audit of three major AI models reveals that personalized user contexts significantly reshape brand recommendations in commercial AI assistants, with mid-market brands experiencing up to 75% recommendation volatility while category leaders maintain 80% consistency across personas. The study demonstrates that AI recommendation bias is strongly correlated with model architecture and retrieval strategies, with implications for fair evaluation and brand perception measurement.

🧠Researchers present a comprehensive framework comparing RAG (Retrieval-Augmented Generation) variants—including GraphRAG, Modular RAG, and Agentic RAG—across 9 standardized scenarios. They introduce a novel context optimization method that reduces token usage by 19-53% while identifying a retrieval-generation gap suggesting advanced retrieval methods may not proportionally improve output quality.

🧠Researchers introduce Critic-R, a framework that improves agentic search systems by creating a feedback loop between reasoning agents and retrieval models. The approach uses a critic model to evaluate whether retrieved context supports reasoning steps and includes two mechanisms: Critic-R-Zero for query refinement at inference time, and Critic-Embed for training retrievers without manual annotations, demonstrating significant improvements on multi-hop question-answering benchmarks.

🧠Researchers propose Video Retrieval Augmented Generation (VRAG) to address fundamental challenges in interactive world models for long-form video generation, specifically tackling compounding errors and spatiotemporal incoherence. The work establishes that autoregressive video generation inherently struggles with error accumulation, while explicit global state conditioning significantly improves long-term consistency and interactive planning capabilities.
