# Unpin Evaluation

DELETE /apis/intake/v2/workspaces/{workspace}/evaluations/{name}/pin

Unpin an evaluation. Idempotent: unpinning an already-unpinned evaluation is a no-op.

Reference: https://docs.nvidia.com/nemo-helix/v0.5.1/documentation/reference/api-reference/evaluations/unpin-evaluation-apis-intake-v-2-workspaces-workspace-evaluations-name-pin-delete

## Request

### Path parameters

- `workspace` (string, required)
- `name` (string, required)

## Response

### 200

Successful Response

- `id` (string, required)
- `name` (string, required)
- `workspace` (string, required)
- `experiment_ids` (list of string, required) — Entity ids of the Experiments this Evaluation belongs to (>=1).
- `dataset_name` (string, required)
- `experiment_group_id` (string, required, deprecated) — Deprecated single-experiment alias; the first of experiment_ids. Use experiment_ids.
- `dataset_version` (string, optional)
- `source_link` (string, optional)
- `metadata` (map from string to string, optional)
- `description` (string, optional)
- `parent_evaluation_id` (string, optional)
- `status` (string, optional)
- `root_cause` (string, optional)
- `created_at` (datetime, optional)
- `updated_at` (datetime, optional)
- `pinned_at` (datetime, optional, nullable) — Timestamp at which the evaluation was pinned, or null if unpinned. Managed via POST/DELETE /evaluations/\{name}/pin.
- `evaluator_names` (list of string, optional)
- `model_names` (list of string, optional) — Distinct model names observed across ingested sessions for this evaluation.
- `agent_names` (list of string, optional) — Distinct agent names observed across ingested sessions for this evaluation.
- `agent_versions` (list of string, optional) — Distinct agent versions observed across ingested sessions for this evaluation.
- `aggregate_scores` (map from string to EvaluatorAggregate, optional)
- `run_count` (integer, optional, default: 0) — Number of distinct ingested evaluation sessions; one session is treated as one run.
- `test_case_count` (integer, optional, default: 0) — Number of distinct test cases in the evaluation, i.e. distinct test_case_name values (sessions with no test_case_name each count as their own). A test case run k times counts once; the rollup metrics are averaged per test case before pooling across test cases.
- `cost_usd` (EvaluatorAggregate, optional) — Aggregate statistics over evaluator scores or session-level metric values.
- `latency_ms` (EvaluatorAggregate, optional) — Aggregate statistics over evaluator scores or session-level metric values.
- `tokens` (EvaluatorAggregate, optional) — Average total tokens (input + output) per test case, aggregated across the evaluation.

## Errors

### 404 Not Found Error

Evaluation not found

- `any`

### 422 Unprocessable Entity Error

Validation Error

- `detail` (list of ValidationError, optional)

## Types

### EvaluatorAggregate

Aggregate statistics over evaluator scores or session-level metric values.

- `sum` (double, optional)
- `mean` (double, optional)
- `median` (double, optional)
- `p90` (double, optional)
- `p95` (double, optional)
- `p99` (double, optional)
- `count` (integer, optional, default: 0)
- `failed_count` (integer, optional, default: 0) — Sessions whose evaluator recorded a FAILED result (ran, produced no value). They are already counted as 0 in `mean`; this says how many of the attempts behind that mean were failures.

### ValidationError

- `loc` (list of ValidationErrorLocItems, required)
- `msg` (string, required)
- `type` (string, required)
- `input` (any, optional)
- `ctx` (map from string to any, optional)

### ValidationErrorLocItems
