Which is cheaper, Claude or Chandra?

Chandra. Claude is 14 credits / page and Chandra is 2 credits / page.

Which is more accurate?

It depends on the document. Claude is strongest at long dense documents, and Chandra at complex layouts and handwriting. Run a few of your own files through both and compare the output.

Yes. Put one as model and the other in fallbacks. If the first fails, the second reads the page, and you pay only for the one that answered.
