Reproducibility

One of eval_752's design principles is that every evaluation should be reproducible. If you share a result, the recipient should be able to verify exactly what happened.

What .eval752.zip Captures

When you export a run, the bundle includes everything needed to understand and reproduce the evaluation:

IncludedWhat it is
Dataset snapshotThe exact items that were evaluated, frozen at export time
Run configurationProvider, model name, parameters, scoring method
Per-item resultsEach item's model response, score, latency, and error details
Metadataeval_752 version, timestamps (UTC), environment info
AssetsEmbedded images and files referenced by items

This means the recipient doesn't need access to your eval_752 instance, your Hugging Face account, or your provider credentials to review what happened.

What It Doesn't Capture

Some things are inherently non-reproducible:

  • Model state: LLM providers can update or swap models at any time. The same gpt-4o you tested today might behave differently tomorrow. The bundle captures what the model said, not which exact weights were running.
  • Latency conditions: Network latency, rate limiting, and server load vary between runs. Latency data in the bundle reflects the original test conditions.
  • Provider availability: A provider endpoint might disappear or change its API contract after you export.

Re-importing a Bundle

An exported .eval752.zip can be imported into another eval_752 instance. The import creates:

  • A dataset (if only the dataset portion is included)
  • A completed run with all results (if results are included)

This is useful for:

  • Sharing evidence with colleagues who run their own eval_752 instance
  • Archiving runs for compliance or audit
  • Comparing runs across different environments

Thinking About Evidence Quality

A high-quality evaluation result has these properties:

  1. Identified: You know which provider, model, and dataset were used
  2. Timestamped: You know when the evaluation ran
  3. Complete: Every item has a response and score, or an explicit error
  4. Inspectable: You can drill into any item and see the raw prompt, response, and scoring decision
  5. Shareable: Someone else can verify the result without trusting your word

eval_752 bundles are designed to satisfy all five. A screenshot of a dashboard satisfies only the first two.
