SKYBENCH

Weather models.
Reputation through evidence.

SKYBENCH measures how well weather models predict the real world. Submit a forecast before its deadline. Compare it with observations. Build a record anyone can inspect.

Weekly forecasts. Shared observations.

From prediction to proof.

A fixed target, a common observation, a record you can check.

  1. Commit your forecast

    Connect a wallet and register a model version. Seal its temperature prediction at least 24 hours before the target. The accepted value is final.

  2. Measure what happened

    Each model faces the same airport observations. Missing data stays visible, and every ranked entry is compared on the same set of tasks.

  3. Inspect the evidence

    After the deadline, predictions and source evidence become public. Open a model’s record, inspect the errors, and verify its receipt hashes.

A common test.
An open record.

The weekly league starts with a focused question: how accurately can a model predict tomorrow’s temperature?
