Evaluation dimensions

Create and manage evaluation dimensions on QwenCloud with LLM numeric scoring, LLM classification, and manual annotation.

Evaluation dimensions define the scoring criteria for evaluation tasks. You can create and manage dimensions on the Evaluation Dimensions console page.

Dimension types

TypeDescriptionScoring methodUse cases
LLM - NumericA judge model scores responses on a numeric scale (e.g. 0-5)Numeric outputQ&A quality, content generation quality
LLM - ClassificationA judge model classifies responses as pass/failLabel outputContent safety, correctness checks
Manual - ClassificationHuman annotators label responses using custom categoriesManual labelingCreativity evaluation, expert judgment
A single evaluation task can combine multiple dimensions to assess model performance from different perspectives.

Create an evaluation dimension

1

Open the create page

On the evaluation dimensions list page, click Create.
2

Enter basic information

Enter a dimension name (required) and description (optional, used to describe the evaluation purpose of the dimension).
3

Select the dimension type

Choose LLM - Numeric, LLM - Classification, or Manual - Classification. The remaining fields vary by type.
4

Configure scoring rules

Complete the type-specific configuration (see below), then click Create.

LLM - Numeric

For scenarios requiring quantitative scoring (e.g. response quality rated 1-5).
FieldDescription
Judge modelThe AI model that performs scoring
Scoring templateA preset scoring prompt template. Options: General evaluation (default — scores across relevance, informativeness, clarity, etc.), Semantic similarity (evaluates how closely the output matches the reference answer), Custom scorer (write your own scoring prompt)
PromptScoring instructions. Supports variables ${prompt}, ${output}, and ${completion}
Score rangeMinimum and maximum scores (default 0-5)
Pass thresholdScores at or above this value are considered passing (default 3)
The following variables can be used in prompts and are automatically replaced with actual content during evaluation:
  • ${prompt} — User input (the question from the evaluation data)
  • ${output} — Model output (the response generated by the evaluated model)
  • ${completion} — Reference answer (the expected answer from the evaluation data, used when a standard answer is available)

LLM - Classification

For binary pass/fail scenarios (e.g. whether a response meets specific criteria, content safety checks).
FieldDescription
Judge modelThe AI model that performs classification
Scoring templateA preset classification prompt template. Options: Standard matching (default), Sentiment analysis (classifies response sentiment), Custom scorer (write your own classification prompt)
PromptClassification instructions. Supports variables ${prompt}, ${output}, and ${completion}. The judge model outputs [[Pass]] or [[Fail]]
LabelsDefine pass and fail label sets. Custom labels can be added (up to 20 per category)

Manual - Classification

For scenarios requiring human judgment. No judge model or prompt configuration is needed.
FieldDescription
LabelsDefine pass and fail label sets. Custom labels can be added (up to 20 per category)

Judge models

LLM-based dimensions support the following judge models (subject to console availability):
  • Qwen3.7-Plus-2026-05-26
  • Qwen3.7-Max-2026-06-08
  • Qwen3.6-Flash-2026-04-16
  • DeepSeek-V4-Pro
  • DeepSeek-V4-Flash

Manage evaluation dimensions

On the evaluation dimensions list page, you can:
  • Filter — Use the type dropdown to filter by dimension type.
  • Details — Click the details button in the actions column to view dimension settings.
  • Delete — Click the delete button in the actions column to remove a dimension.
Evaluation dimensions referenced by evaluation tasks cannot be deleted. To delete a dimension, first delete the evaluation tasks that reference it.
