Get Experiment Run Metrics

Get metrics for an experiment run.

Requires the run_id query parameter. Use view to choose the breakdown (summary, by_document, by_target, or votes), and narrow with document_id or target_path. By default each score-bearing row also carries a prior_score from the previous completed run; pass include_prior=false to omit it or prior_run_id to compare against a specific run.

from retab import Retab

summary = client.workflows.experiments.metrics.get(
    "exprun_2",

target_view = client.workflows.experiments.metrics.get(
    "exprun_2",
    view="by_target",
    target_path="line_items.*.unit_price",

Get metrics for a specific experiment run. Metrics are consensus likelihoods on the [0.0, 1.0] scale where 0.0 is low agreement and 1.0 is total agreement.

The view query parameter selects one of four successful response shapes. In responses, branch on kind; it is the shared discriminator for success and data-state payloads such as stale_metrics and no_metrics.

View	Use it to
summary	Read the overall score plus block-specific aggregates. Start here.
by_document	Drill into one document and see all its targets, sorted ascending. Requires document_id.
by_target	Drill into one target and see its score across every document. Requires target_path.
votes	See the per-voter consensus rows for one document/target cell. Requires both document_id and target_path.

Pass include_prior=false to omit prior-run comparison fields, or prior_run_id=... to override which run is treated as the prior.
