Good and poor fit

Good fit
  • Reading screenshots, charts, scanned documents and photos.
  • Whole codebases, contract bundles and long transcripts in a single pass.
Poor fit
  • Classification, routing and short summaries — a small model does these identically for a fraction of the price.
  • Integrations that depend on structured function calls.
