from openjudge.models.openai_chat_model import OpenAIChatModel
from openjudge.graders.common.correctness import CorrectnessGrader
from openjudge.runner.grading_runner import GradingRunner
# 1. Configure the judge model (OpenAI-compatible endpoint)
model = OpenAIChatModel(
model="qwen-plus",
api_key="sk-xxx",
base_url="https://dashscope.aliyuncs.com/compatible-mode/v1",
)
# 2. Instantiate a grader
grader = CorrectnessGrader(model=model)
# 3. Prepare dataset

"reference_response": "Paris.",
},
{

GraderRank | Listwise result: .rank (List[int]), .reason (str), .metadata (dict) |

RunnerResult | Dict[str, List[GraderResult]] — keyed by grader name |
from openjudge.graders.schema import GraderScore, GraderRank, GraderError
for grader_name, grader_results in results.items():

# Option B: dict (auto-creates OpenAIChatModel)

# OpenJudge Skill
Build evaluation pipelines for LLM applications using the `openjudge` library.
## When to Use This Skill
- User wants to evaluate LLM output quality (correctness, relevance, hallucination, etc.)
- User wants to compare two or more models and rank them
- User wants to design a scoring rubric and automate evaluation
- User wants to analyze evaluation results statistically
- User wants to build a reward model or quality filter

## 5-Minute Quick Start
Evaluate responses for correctness using a built-in grader:
```python
import asyncio
from openjudge.models.openai_chat_model import OpenAIChatModel
from openjudge.graders.common.correctness import CorrectnessGrader
from openjudge.runner.grading_runner import GradingRunner
# 1. Configure the judge model (OpenAI-compatible endpoint)
model = OpenAIChatModel(
model="qwen-plus",
api_key="sk-xxx",
base_url="https://dashscope.aliyuncs.com/compatible-mode/v1",
)
# 2. Instantiate a grader
grader = CorrectnessGrader(model=model)
# 3. Prepare dataset
dataset = [
{
"query": "What is the capital of France?",
"response": "Paris is the capital of France.",
"reference_response": "Paris.",
},
{
"query": "What is 2 + 2?",
"response": "The answer is five.",
"reference_response": "4.",
},
]
# 4. Run evaluation
async def main():
runner = GradingRunner(
grader_configs={"correctness": grader},
max_concurrency=8,
)
results = await runner.arun(dataset)
for i, result in enumerate(results["correctness"]):
print(f"[{i}] score={result.score} reason={result.reason}")
asyncio.run(main())
```
**Expected output:**
```
[0] score=5 reason=The response accurately states Paris as capital...
[1] score=1 reason=The response gives the wrong answer (five vs 4)...
```
## Key Data Types
| Type | Description |
|------|-------------|
| `GraderScore` | Pointwise result: `.score` (float), `.reason` (str), `.metadata` (dict) |
| `GraderRank` | Listwise result: `.rank` (List[int]), `.reason` (str), `.metadata` (dict) |
| `GraderError` | Error during evaluation: `.error` (str), `.reason` (str) |
| `RunnerResult` | `Dict[str, List[GraderResult]]` — keyed by grader name |
## Result Handling Pattern
```python
from openjudge.graders.schema import GraderScore, GraderRank, GraderError
for grader_name, grader_results in results.items():
for i, result in enumerate(grader_results):
if isinstance(result, GraderScore):
print(f"{grader_name}[{i}]: score={result.score}")
elif isinstance(result, GraderRank):
print(f"{grader_name}[{i}]: rank={result.rank}")
elif isinstance(result, GraderError):
print(f"{grader_name}[{i}]: ERROR — {result.error}")
```
## Model Configuration
All LLM-based graders accept either a `BaseChatModel` instance or a dict config:
```python
# Option A: instance
from openjudge.models.openai_chat_model import OpenAIChatModel
model = OpenAIChatModel(model="gpt-4o", api_key="sk-...")
# Option B: dict (auto-creates OpenAIChatModel)
model_cfg = {"model": "gpt-4o", "api_key": "sk-..."}
grader = CorrectnessGrader(model=model_cfg)
# OpenAI-compatible endpoints (DashScope / local / etc.)
model = OpenAIChatModel(
model="qwen-plus",
api_key="sk-xxx",
base_url="https://dashscope.aliyuncs.com/compatible-mode/v1",
)
```
