The decision context
Multimodal is an input-and-output capability label, not a guarantee that a model can read every chart, recording, scan, frame sequence, or document layout reliably. Supported formats, preprocessing, resolution, ordering, and endpoint behavior all shape the result.
A useful pilot preserves the original artifact, the transformation sent to the model, and the evidence location behind each material output. Accessibility, privacy, copyright, and domain-review requirements belong in the same test plan.
Why it matters
- OCR, layout, temporal sequence, and visual inference can fail in different ways.
- Product interfaces may preprocess media differently from developer APIs.
- A fluent cross-modal answer can conceal that the decisive evidence was unreadable or absent.
Questions to answer before choosing
- Which modalities and file conditions occur in real work?
- What source coordinate—page, timestamp, region, or frame—must support each claim?
- How does preprocessing alter resolution, ordering, metadata, or privacy exposure?
- Which outputs require a qualified visual, audio, medical, legal, or domain reviewer?
A reviewable decision path
Each step should leave a record that another reviewer can inspect.
- 01
Sample real artifacts
Include scans, small text, noisy audio, long video, mixed layouts, and adversarial edge cases.
- 02
Preserve provenance
Keep original files and record every conversion, crop, compression, and ordering decision.
- 03
Request coordinates
Require page, time, frame, or region references where the source supports them.
- 04
Score by failure type
Separate extraction, grounding, reasoning, formatting, and refusal failures.
- 05
Verify endpoint parity
Do not assume a consumer app and API use identical preprocessing or models.
