Model Hallucination
A phenomenon in which large language models generate content that is factually incorrect or unverifiable with high apparent confidence. It represents one of the primary reliability challenges in current LLMs and affects model trustworthiness in high-stakes scenarios.
Core Facts
Strategies for mitigating LLM hallucination include retrieval-augmented generation (RAG), chain-of-thought prompting, and requiring the model to output confidence scores.
In multi-step automation scenarios, single-step errors caused by model hallucinations are amplified exponentially along the task chain.
Model hallucination refers to models generating outputs that appear plausible but are actually incorrect, requiring robust rollback, retry, and human intervention mechanisms to address.
Timeline (last 90 days)
Hallucination is not a program bug, but an inherent byproduct of the model's working mechanism of probabilistically predicting the next word.
Large model projects face engineering issues such as hallucinated data fabrication, outputting pseudo-tool tags, and using outdated training knowledge to override the latest data returned by tools.
In code generation scenarios, models may call non-existent APIs, modify functions that should not be touched, or break existing logic without proactively reporting the changes
AI hallucinations in government information services are compounded by an authority halo effect, as users tend to trust information from official channels more, making error correction more difficult.
Engineering approaches to mitigating hallucinations include adding a result validation layer to tool calls, introducing RAG retrieval-augmented generation, setting confidence thresholds to trigger human review, and using prompts to constrain the model to proactively declare when it does not know something.
