evidence review on multimodal hallucination mitigation techniques

Current multimodal research suggests hallucination mitigation improves when generation is constrained by grounding signals from retrieved text, image metadata, or explicit verifier stages (arXiv).

evidence map

• Grounded decoding lowers fabricated entity rates in visual QA tasks.
• Verifier loops catch inconsistent cross-modal claims.
• Gains vary by domain and annotation quality.

practical boundary

Mitigation quality depends on verifier recall and calibration, not just adding an extra model step.

my take

Multimodal reliability improves when teams treat grounding as architecture, not as post-processing.
