Language Model Benchmark Reproduction Framework

A comparable benchmark run preserves the system and protocol as part of the result.

RecordRequired fields
ClaimPublisher score, date, benchmark, comparison, and source
SystemArtifact revision or endpoint, provider, runtime, template, and wrapper
EnvironmentCode revision, dependencies, hardware, precision, quantization, and container
DatasetName, version, split, preprocessing, contamination checks, and exclusions
PromptSystem prompt, user format, examples, ordering, and output parser
InferenceTemperature, top-p, max tokens, seed, batching, retries, and stop conditions
ScoringMetric implementation, normalization, parser, aggregation, and uncertainty
OutputRaw requests, responses, logs, errors, excluded cases, and final table

Stanford HELM demonstrates standardized scenarios, prompts, metrics, and transparent results. NIST's draft automated-benchmark work emphasizes validity, transparency, and reproducibility.

Provider drift, hidden routing, nondeterminism, contamination, and benchmark relevance can remain even after the manifest is complete. A reproduction report should publish deviations and failed attempts rather than force agreement.
