What are the current state-of-the-art techniques for reducing hallucinations...

I’m studying how modern large language models (LLMs) generate factual and verifiable outputs. Despite improvements in training data quality and model alignment, hallucinations still occur. My question is: What are the most effective model-level and system-level methods currently used to reduce hallucinations in LLMs? I’m especially interested in techniques used in production systems, such as: retrieval-augmented generation (RAG) tool-use or...

Great question — answering as the UphillTech team:

For retrieval-augmented generation (RAG), you can refer to Towards Trustworthy Retrieval Augmented Generation for Large Language Models: A Survey . Aside from the technique you listed, one can also steer LLMs to be more faithful (ICLR 2026).
