01
Correctness & instruction following
Review whether a response answers the request, follows its constraints, and is supported by the task's references. Define how reviewers handle uncertainty and insufficient evidence.
Human evaluation / Model responses
Human preference.
Judgment you can use.
Understand which responses people prefer and why. We manage human comparison and scoring of model outputs against your requirements for correctness, instruction following, usefulness, and conversational quality.
What we evaluate
Beyond a winner and a loser.
A preference label is more useful when you know what drove it. We separate the dimensions of response quality so your team can understand the tradeoffs behind a judgment.
02
Usefulness & relevance
Judge whether the response gives the user what they need to move forward. Review relevance, completeness, clarity, and unnecessary content against the intended task.
03
Conversational quality
Evaluate how well a response fits the exchange: continuity, tone, appropriate detail, and handling of ambiguity. Compare alternatives using the same context and criteria.
Evaluation rubric
Make preference a defined task.
We build the evaluation around your use case, with explicit scoring rules and written reasoning that makes reviewer decisions inspectable.
- Comparison rules
- Define pairwise preference or ranked responses, including ties and cases that cannot be judged from the supplied evidence.
- Scoring dimensions
- Set criteria for correctness, instruction following, usefulness, and conversational quality, with examples that anchor the ratings.
- Decision rationale
- Require explanations tied to the response and rubric. Route conflicting or ambiguous judgments through adjudication.
Execution & quality assurance
A managed evaluation workflow.
We manage the people, instructions, and review process needed to turn subjective judgments into a consistent evaluation dataset.
- 01
Define the rubric
Agree on the evaluation task, response context, reference material, scoring dimensions, and output schema.
- 02
Qualify & calibrate
Prepare reviewers on the task and calibrate their judgments against shared examples and decision rules.
- 03
Compare & explain
Run response comparisons and scoring. Collect written explanations and review decisions for consistency with the rubric.
- 04
Adjudicate & deliver
Resolve disagreements, record final labels, and check the delivered records against your format and acceptance criteria.
What you receive
Preferences with a reason behind them.
Receive structured evaluation records that preserve the connection between the prompt, the responses, and the final human judgment.
- Rankings & dimension scores
- Response preferences and ratings organized by prompt, response identifiers, and the agreed evaluation criteria.
- Written explanations
- Reasoning that connects the judgment to specific response content and rubric requirements.
- Adjudicated labels
- Reviewed final decisions, rubric references, and disagreement resolutions in the format your team needs.
