Claude Fable 5.1 runs the forecast overnight

Claude Fable 5.1 can build a forecast from raw data on its own, and it checks its numbers as it goes.

In this example, one person at a B2B company maintains the revenue forecast for a business with a mix of contract and consumption revenue. Claude updates the forecast overnight, running unattended on our API. In the morning, the analyst asks how accurate past forecasts have been, and Claude backtests itself on the spot. The analyst reviews and approves before anything goes out.
