Break multimodal tasks into skills
List the exact modalities involved: text, image, chart, PDF, spreadsheet, screen, audio, video, or tool calls. A model that reads screenshots well may still fail at precise document extraction.
Evaluate each skill separately before combining them into a workflow. This makes failures diagnosable.
Use task-specific rubrics
For images, score object recognition, spatial reasoning, text reading, and uncertainty. For audio, score transcription, speaker handling, latency, and pronunciation. For screen use, score safe action selection and recovery from UI changes.
Ask the model to expose assumptions when visual evidence is ambiguous. Overconfident visual answers are risky in support, compliance, and operations workflows.
Test messy real inputs
Use blurry screenshots, cropped charts, low-quality audio, long PDFs, rotated images, and files with missing context. Clean demos rarely represent production.
Track whether the model asks for more information when it should. A good multimodal system knows when the evidence is not enough.
Practical checklist
- 1Separate every modality in the workflow.
- 2Use rubrics for each modality.
- 3Test messy real-world inputs.
- 4Measure uncertainty behavior.
- 5Review privacy for uploaded files and media.
