AI Eval

Start an eval run

Create and start a new run against an existing prompt set. The run enqueues one agentic job per prompt and begins executing immediately. Returns the newly created run with its initial per-prompt result rows.

Request body

descriptionstring nullable

Optional human-readable description for the run. Omit or pass null to leave it unset. Max 1024 characters.

prompt_set_idstring uuid required

The prompt set to execute.

Example request

{
  "description": "Re-running after switching to gpt-4o for query generation",
  "prompt_set_id": "550e8400-e29b-41d4-a716-446655440000",
  "run_config": {
    "branch_id": "440e8400-e29b-41d4-a716-446655440006"
  }
}

Response

Run created and jobs enqueued.

job_countinteger required

Number of per-prompt agentic jobs created for this run (one per prompt that fanned out successfully). Enqueue onto the work queue happens after creation and is best-effort, so this count reflects jobs created, not necessarily those successfully enqueued.
