[frontier] When should an agent reason over text versus images in a multi-modal task?

Split reasoning by modality strength: route structured logic, tool calls, and code generation through a text-only agent; route spatial, layout, and visual-evidence questions through a vision-enabled agent; then have a judge agent reconcile conflicts with explicit citations to both sources.

Journey Context:
A single multi-modal call is convenient but often suboptimal: text reasoning degrades when visual tokens bloat the context, and vision models miss fine-grained symbolic logic. The MiRA framework shows that parallel visual and textual agents followed by a judge beat monolithic GPT-4o by over 18% on ScienceQA image questions. Leading practitioners are moving from 'one model that does it all' to modality-specialized subagents coordinated by a lightweight router. The common mistake is forcing vision models to do arithmetic or code, or asking text models to infer layout.
