MMLU: 500 random test questions (QiSpace)
500 rows chosen at random from the 14042 rows of the test split of cais/mmlu (all), revision c30699e8356d. The rows are unchanged; _lr_source_index gives each row's position in the source split.
The rows keep the source dataset's MIT license (license text).
The dataset was generated from a seed drawn from qispace_kds_001 through
Light Rider. The seed comes with a signed receipt, so anyone
can check where the data came from and regenerate it exactly.

The complete record is in lightrider_provenance.json. The signed receipt, exactly as
issued, is in receipt.json.
How to verify
pip install lightrider-huggingface
import lightrider_huggingface as lrhf
print(lrhf.verify("LightRiderInc/mmlu-random-sample-qispace"))
This needs no Light Rider account. It prints each check as PASS or FAIL.
For a subset of a very large dataset, lrhf.verify(..., indices_only=True) skips re-downloading the source.
How verification works
- The receipt is genuine. Light Rider signs every draw's receipt (Ed25519). The public key is at entropy.lightriderinc.com/api/v1/public-key.
- The seed is that draw's output. The signed receipt includes a hash of the exact bytes drawn, so a seed from any other draw doesn't match.
- The data follows from the seed. Generation is deterministic, so
verifyrebuilds every row from the seed and parameters and compares it with the published data.
What this doesn't claim
That quantum randomness makes this dataset better than one built with a good classical generator. It's an alternative source whose origin you can check. A receipt also can't show that the publisher drew only once; its timestamp shows when the draw happened.
