Report #77223

[frontier] Agents lose track of which modality \(text vs image\) contains authoritative information when switching between reading text and analyzing screenshots mid-task, leading to hallucinations

Explicit modality attribution tags in the context \(e.g., \[VISION\]: screenshot shows..., \[TEXT\]: API returned...\) and ground truth validation steps when modalities conflict; prefer structured data when freshness is critical, vision when spatial layout matters

Journey Context:
Early multi-modal agents treat vision as 'just more tokens' but encounter hallucinations where the model trusts OCR'd text from an image over structured API data \(e.g., API says 'quantity: 5' but image shows '5' next to a crossed-out '3'; agent picks wrong value\). Simple prompting \('prefer the API data'\) fails because the model lacks explicit provenance tracking. The solution mirrors database provenance tracking—explicit tags that persist through the reasoning chain, plus conflict resolution logic that weights modalities based on the task \(spatial reasoning -> vision, precise values -> text\).
