• Fanar-Sadiq: A Multi-Agent Architecture for Grounded Islamic QA \ Large language models (LLMs) can answer religious knowledge queries fluently, yet they often hallucinate and misattribute sources, which is especially consequential in Islamic settings where users expect grounding in canonical texts (Qur'a… \ Source • arXiv cs.CL • 16:35
• One Model Is Enough: Native Retrieval Embeddings from LLM Agent Hidden States \ LLM agents that retrieve external knowledge typically generate a search query as text, then run a separate embedding model to encode it into a vector. This two-model pipeline adds infrastructure complexity and latency, yet is redundant: th… \ Source • arXiv cs.CL • 15:25
