Evaluation Settings

A dataset’s questions and its grading config (acceptance criteria, similarity metrics, thresholds) are independent. EvaluationSettings is the grading config half on its own: build it once, then run it against any dataset by id, instead of every dataset carrying its own copy. Passing evaluation_settings_id is entirely optional. Omit it and a run grades against the dataset’s own bundled config, exactly as if this feature didn’t exist.

Programmatic builder

evaluation_settings = client.evaluations.settings.builder(
    name="Strict - production bar",
    number_of_requests=3,
    acceptance_criteria="Accurate, concise, grounded in the support policy.",
    rejection_criteria="No hallucinated policies or made-up steps.",
    vector_similarity=True,
    jaccard_similarity=True,
).publish()

print(evaluation_settings.id)

`builder()` parameters

Parameter	Type	Default	Description
`name`	`str`	required	Config display name
`description`	`str`	none	Human-readable description
`number_of_requests`	`int`	`1`	How many times each question is run per evaluation, for consistency testing
`acceptance_criteria`	`str`	none	What a good response looks like, included in the LLM scoring prompt
`rejection_criteria`	`str`	none	What a bad response looks like, included in the LLM scoring prompt
`evaluation_criteria`	`str`	none	Scoring rubric, included in the LLM scoring prompt
`vector_similarity`	`bool`	`False`	Enable cosine similarity scoring against `expected_results`
`jaccard_similarity`	`bool`	`False`	Enable Jaccard token-overlap scoring against `expected_results`
`bleu_score`	`bool`	`False`	Enable BLEU scoring against `expected_results`
`rouge_score`	`bool`	`False`	Enable ROUGE scoring against `expected_results`
`similarity_model`	`str`	provider default	Embedding model used for vector similarity, e.g. `"text-embedding-3-small"`
`sovereignty_models`	`list[str]`	none	Enables Sovereignty & Portability; models to compare when this config runs. Discover valid ids with `client.evaluations.list_models()`
`judge_prompt`	`str`	server default	Override the LLM-as-judge’s raw prompt template. See Configuring the judge
`judge_model`	`str`	`"gpt-5.5"`	Override the LLM-as-judge’s model (any OpenAI or Anthropic id from `client.evaluations.list_models()`)

publish() sends the config to AgentX and returns an EvaluationSettings object with .id, which you pass as evaluation_settings_id to client.evaluations.run().

Configuring the judge

judge_prompt/judge_model apply to every scoring path, native dashboard runs and SDK/custom-agent runs alike:

evaluation_settings = client.evaluations.settings.builder(
    name="Strict - production bar",
    judge_model="claude-opus-4-8",
    judge_prompt="""You are grading a customer support response.

**User Query:** {input}

**Agent Response:**
{output}

**Expected Results:**
{expected}

Score strictly: any missing policy detail is a failing response.""",
).publish()

judge_prompt is a raw template: {input}, {output}, and {expected} are substituted in. Everything else the judge needs (chain of thought, capabilities/references, criteria, per-question judge_guideline, delegation notes) is appended automatically after it, so a custom prompt can restructure the grading philosophy without ever losing that context. Omit judge_prompt to keep the default rubric, or judge_model to keep the default (gpt-5.5).

Running against a dataset

report = (
    client.evaluations
    .run(
        dataset_id="...",
        subject={"kind": "custom_agent", "displayName": "Support Bot", "framework": "langchain", "runtime": "local"},
        evaluation_settings_id=evaluation_settings.id,
    )
    .execute(my_agent)
    .finalize()
    .analyze()
)

The same evaluation_settings_id can be reused across as many dataset_ids as you want. Build it once, grade any dataset with it going forward.
