Create an accessible narration from a chart-heavy PDF deck

Goal

Goal: Pass a presentation as a multimodal PDF and produce a structured narration that explains charts.

Steps

1. Export slides to PDF and check total pages against the model PDF limit and remove sensitive content. [multimodal]
2. Use messages.create(model=..., max_tokens=8192, messages=[...document block...]) to extract figures, trends, and definitions; require uncertainty labels. [multimodal]
3. Request narration per slide and parse stable tags; compare samples with source slides and independently recompute calculations. [multimodal]

How to verify

Verify values, units, trend direction, and labels against source slides; ensure narration covers key visual information.

Troubleshooting

For dense charts ask for a point-by-point description; model arithmetic can be wrong, so use a calculator or recompute independently.
