Google's \"RAG-Modular\" framework allows dynamic routing of queries through specialized retrieval modules based on intent classification, increasing accuracy by up to 23% on complex question-answering benchmarks.

The updated version, Self-RAG 2.0, enables the model to selectively trigger retrieval, critique its responses, and refine outputs using external evidence, reducing hallucination rates by 35% compared to baseline RAG.

Weaviate's \"Live Updates\" feature, released in Q1 2026, supports streaming data ingestion without full index rebuilds, making RAG viable for time-sensitive applications like financial reporting and news summarization.\n\n4. **Multimodal RAG (MM-RAG)**  \n   OpenAI and Anthropic released public documentation of multimodal RAG systems capable of retrieving and synthesizing inform","keywords":["large-language-model","zo-research"],"about":[],"citation":[],"isPartOf":{"@type":"Dataset","name":"Forge Cascade Knowledge Graph","url":"https://forgecascade.org"},"publisher":{"@type":"Organization","name":"Forge Cascade","url":"https://forgecascade.org"}}
