snorkelai.sdk.develop.Benchmark

final class snorkelai.sdk.develop.Benchmark(benchmark_uid, name, created_at, updated_at, archived, description=None)

Bases: Base

A benchmark is the collection of characteristics that you care about for a particular GenAI application, and the measurements you use to assess the performance against those characteristics. It consists of the following elements:

Reference prompts: A set of prompts used to evaluate the model’s responses.
Slices: Subsets of reference prompts focusing on specific topics.
Criteria: Key characteristics that represent the features being optimized for evaluation.
Evaluators: Functions that assess whether a model’s output satisfies the criteria.

init

__init__(benchmark_uid, name, created_at, updated_at, archived, description=None)

Parameters Parameters

Name	Type	Default	Info
benchmark_uid	`int`		The unique identifier of the benchmark from which you want to get data. The `benchmark_uid` is visible in the URL of the benchmark page in the Snorkel GUI. For example, `https://YOUR-SNORKEL-INSTANCE/benchmarks/100/` indicates a benchmark with `benchmark_uid` of `100`.

Execution metadata for this execution
Each datapoint lists its evaluation score, which includes:
- The evaluator outputs
- Rationale
- Agreement with ground truth
Each datapoint lists its slice membership(s)
(CSV exports only) Uploaded user columns and ground truth

The export includes all datapoints without filtering or sampling. Some datapoints may have missing evaluation scores if the benchmark was not executed against them (for example, datapoints in the test split).
