Questions people ask

How accurate are these numbers?

They are estimated from the image by two independent passes, with confidence 0.51 on a 0 to 1 scale. Printed numbers read well; values read off an axis can be a few percent off.

Can I reuse this data?

The numbers describe a chart that Anthropic published. The image, layout and styling belong to them. Use the numbers with a credit to the publisher, and make your picture from your own data.

How do I get the file?

The JSON, CSV and agent skill file are under the email gate on this page. In this prototype they are static files at /api/charts/5273d2829012.json and /api/charts/5273d2829012.skill.md.
