A gold-level benchmark result is not a research reliability certificate

What the laboratory reports

• DeepMind reports gold-medal-standard performance on the 2025 International Mathematical Olympiad problems under the competition's evaluation process.
• The system produced natural-language proofs within the official time limit.
• The result demonstrates high capability on a small, prestigious and bounded set of problems.

The mathematical problem

Benchmark transfer is an extrapolation problem. A score on a narrow distribution does not identify error rates on literature-dependent, ambiguous, adversarial or open-ended research tasks without a model of distribution shift.

GERO's proposed response

• Preserve the benchmark result as scoped evidence instead of converting it into a general reliability claim.
• Build a transfer matrix across contest proofs, textbook proofs, research reconstructions and open problems.
• Measure how calibration and false acceptance change with dependency length and semantic ambiguity.

A falsifiable experiment

• Match tasks by mathematical area while varying openness, literature dependence and proof length.
• Blindly inject semantic and logical defects into candidate proofs.
• Estimate the coverage at which a declared false-acceptance threshold can be maintained.
