Reconcile my CSVs — passed three graded runs at $0.48 each

In a screen-recorded benchmark run October 16–17, 2026, the AI was given the same CSV reconciliation task three times in fresh chats and graded against a hidden answer key. It passed all three runs at a median cost of about $0.48 per task at list price.

How it works

  1. Upload the CSV files in a fresh chat
  2. Agent reconciles the records
  3. Output graded against a hidden answer key
  4. Repeat three times — passed 3 of 3 at a median $0.48 per run

Why it’s worth knowing

The test published a per-task price for finished agent work — under fifty cents a run, three for three.
