answer_relevance

Low cost

Checks whether the output directly addresses the user's question or task.

quality

Medium cost

Detects demographic, political, or other unfair bias in model outputs.

safety

citation_correctness

Medium cost

Checks whether citations in the output correctly point at source material that supports the cited claim.

quality
retrieval

context_utilization

Medium cost

Measures how effectively the model used the provided context when producing the output.

quality
retrieval

cost_threshold

Low cost

Flags traces where the token cost of the output exceeds a configured limit.

cost
quality

factual_accuracy

Medium cost

Verifies factual claims in the output against widely known ground truth.

quality

faithfulness

Low cost

Checks whether the output is fully supported by the provided input context (no unsupported claims).

quality
retrieval

function_call_correctness

Low cost

Checks whether the model chose the correct tool/function and supplied valid arguments.

tool-use

groundedness

Low cost

Checks whether the output is grounded in the retrieved context, with no free-floating generation.

quality
retrieval

hallucination

Medium cost

Detects fabricated facts, invented citations, or claims not supported by the input.

quality
safety

jailbreak

Medium cost

Detects whether the model was successfully jailbroken — followed instructions to bypass its own safety policies.

safety

json_schema_conformance

Low cost

Checks whether the output is valid JSON and conforms to the expected schema described in the input.

tool-use

language_conformance

Low cost

Verifies the output is written in the language requested by the input.

quality

latency_threshold

Low cost

Flags traces where wall-clock latency exceeds a configured limit.

performance
quality

multi_turn_consistency

Medium cost

Checks that multi-turn conversations remain internally consistent across turns (no contradictions with earlier statements).

quality

output_format_compliance

Low cost

Validates that the output conforms to a specified schema, structure, or format described in the input.

tool-use
quality

pii_leakage

Low cost

Detects personally identifiable information leaking into the output (emails, SSNs, phone numbers, addresses).

safety

prompt_injection

Medium cost

Detects whether untrusted input content was able to override the system's original instructions.

safety

prompt_injection_resistance

Medium cost

Detects whether the model successfully resisted prompt injection attempts embedded in the input.

safety

refusal_appropriateness

Medium cost

Checks whether refusals are appropriately calibrated — the model refuses truly disallowed requests and does not over-refuse benign ones.

safety
quality

retrieval_precision

Low cost

Checks whether the retrieved documents in the input are relevant to the user's query (few irrelevant chunks).

retrieval

retrieval_recall

Low cost

Checks whether the retrieved context contains enough information to fully answer the query.

retrieval

sentiment_match

Low cost

Checks that output sentiment matches the expected sentiment label provided in the input.

quality

tool_choice_correctness

Low cost

Validates that the model selected the right tool for the task, independent of its argument correctness.

tool-use

toxicity

Low cost

Detects harmful, hateful, harassing, or abusive content in the output.
