In prompt engineering, boundary constraints, requiring source citations, and specifying "say you don't know if you don't know" can reduce the probability of hallucination, but cannot be eradicated at the mechanism level.

UnverifiedRelying on prompt constraints to prevent dangerous operations is inherently unreliable, because the model may be jailbroken, make misjudgments, or forget constraints during long conversations.75% similarUnverifiedEnterprise AI products should have anti-hallucination mechanisms built in at the architecture level, including mandatory source citation, confidence threshold settings, and explicit refusal to answer questions that cannot be determined.75% similarUnverifiedFor Q&A requirements that involve ambiguous rules, subjective judgment, or exploratory queries, the deterministic rules engine becomes a constraint and is not suitable for the Adjudicated Query pattern.75% similarUnverifiedForced abstention means the system proactively outputs 'I don't know' when valid evidence is lacking, and this gating is decided by code rather than by the model.74% similarUnverified约束驱动提示（明确告知AI不应做什么）往往比目标驱动提示更能减少幻觉输出74% similar
