🚀 Quick Start

Basic Usage

import asyncio
from evaluatorq import evaluatorq, job, DataPoint, EvaluationResult

@job("text-analyzer")
async def text_analyzer(data: DataPoint, row: int):
    """Analyze text data and return analysis results."""
    text = data.inputs["text"]
    analysis = {
        "length": len(text),
        "word_count": len(text.split()),
        "uppercase": text.upper(),
    }

    return analysis

async def length_check_scorer(params):
    """Evaluate if output length is sufficient."""
    output = params["output"]
    passes_check = output["length"] > 10

    return EvaluationResult(
        value=1 if passes_check else 0,
        explanation=(
            "Output length is sufficient"
            if passes_check
            else f"Output too short ({output['length']} chars, need >10)"
        )
    )

async def main():
    await evaluatorq(
        "text-analysis",
        data=[
            DataPoint(inputs={"text": "Hello world"}),
            DataPoint(inputs={"text": "Testing evaluation"}),
        ],
        jobs=[text_analyzer],
        evaluators=[
            {
                "name": "length-check",
                "scorer": length_check_scorer,
            }
        ],
    )

if __name__ == "__main__":
    asyncio.run(main())

Using Orq Platform Datasets

import asyncio
from evaluatorq import evaluatorq, job, DataPoint, EvaluationResult

@job("processor")
async def processor(data: DataPoint, row: int):
    """Process each data point from the dataset."""
    result = await process_data(data)
    return result

async def accuracy_scorer(params):
    """Calculate accuracy by comparing output with expected results."""
    data = params["data"]
    output = params["output"]

    score = calculate_score(output, data.expected_output)

    if score > 0.8:
        explanation = "High accuracy match"
    elif score > 0.5:
        explanation = "Partial match"
    else:
        explanation = "Low accuracy match"

    return EvaluationResult(value=score, explanation=explanation)

async def main():
    # Requires ORQ_API_KEY environment variable
    await evaluatorq(
        "dataset-evaluation",
        data={"dataset_id": "your-dataset-id"},  # From Orq platform
        jobs=[processor],
        evaluators=[
            {
                "name": "accuracy",
                "scorer": accuracy_scorer,
            }
        ],
    )

if __name__ == "__main__":
    asyncio.run(main())

Advanced Features

Multiple Jobs

Run multiple jobs in parallel for each data point:

from evaluatorq import job

@job("preprocessor")
async def preprocessor(data: DataPoint, row: int):
    result = await preprocess(data)
    return result

@job("analyzer")
async def analyzer(data: DataPoint, row: int):
    result = await analyze(data)
    return result

@job("transformer")
async def transformer(data: DataPoint, row: int):
    result = await transform(data)
    return result

await evaluatorq(
    "multi-job-eval",
    data=[...],
    jobs=[preprocessor, analyzer, transformer],
    evaluators=[...],
)

The @job() Decorator

The @job() decorator provides two key benefits:

1. Eliminates boilerplate - No need to manually wrap returns with {"name": ..., "output": ...}
2. Preserves job names in errors - When a job fails, the error will include the job name for better debugging

Decorator pattern (recommended):

from evaluatorq import job

@job("text-processor")
async def process_text(data: DataPoint, row: int):
    # Clean return - just the data!
    return {"result": data.inputs["text"].upper()}

Functional pattern (for lambdas):

from evaluatorq import job

# Simple transformations with lambda
uppercase_job = job("uppercase", lambda data, row: data.inputs["text"].upper())
word_count_job = job("word-count", lambda data, row: len(data.inputs["text"].split()))

Manual pattern (not recommended):

# Without decorator - requires manual wrapper every time
async def process_text(data: DataPoint, row: int):
    return {"name": "text-processor", "output": {"result": data.inputs["text"].upper()}}

Automatic Error Handling

The @job() decorator automatically preserves job names even when errors occur:

from evaluatorq import job

@job("risky-job")
async def risky_operation(data: DataPoint, row: int):
    # If this raises an error, the job name "risky-job" will be preserved
    result = await potentially_failing_operation(data)
    return result

await evaluatorq(
    "error-handling",
    data=[...],
    jobs=[risky_operation],
    evaluators=[...],
)

# Error output will show: "Job 'risky-job' failed: <error details>"
# Without @job decorator, you'd only see: "<error details>"

Async Data Sources

import asyncio

# Create an array of coroutines for async data
async def get_data_point(i: int) -> DataPoint:
    await asyncio.sleep(0.01)  # Simulate async data fetching
    return DataPoint(inputs={"value": i})

data_promises = [get_data_point(i) for i in range(1000)]

await evaluatorq(
    "async-eval",
    data=data_promises,
    jobs=[...],
    evaluators=[...],
)

Controlling Parallelism

await evaluatorq(
    "parallel-eval",
    data=[...],
    jobs=[...],
    evaluators=[...],
    parallelism=10,  # Run up to 10 jobs concurrently
)

Disable Progress Display

# Get raw results without terminal output
results = await evaluatorq(
    "silent-eval",
    data=[...],
    jobs=[...],
    evaluators=[...],
    print_results=False,  # Disable progress and table display
)

# Process results programmatically
for result in results:
    print(result.data_point.inputs)
    for job_result in result.job_results:
        print(f"{job_result.job_name}: {job_result.output}")

🔧 Configuration

Environment Variables

• ORQ_API_KEY: API key for Orq platform integration (required for dataset access and sending results)

Evaluation Parameters

Parameters are validated at runtime using Pydantic. The evaluatorq function supports three calling styles:

from evaluatorq import evaluatorq, EvaluatorParams

# 1. Keyword arguments (recommended)
await evaluatorq(
    "my-eval",
    data=[...],
    jobs=[...],
    parallelism=5,
)

# 2. Dict style
await evaluatorq("my-eval", {
    "data": [...],
    "jobs": [...],
    "parallelism": 5,
})

# 3. EvaluatorParams instance
await evaluatorq("my-eval", EvaluatorParams(
    data=[...],
    jobs=[...],
    parallelism=5,
))

Parameter Reference

Parameter	Type	Default	Description
data	list[DataPoint] | list[Awaitable[DataPoint]] | DatasetIdInput	required	Data to evaluate
jobs	list[Job]	required	Jobs to run on each data point
evaluators	list[Evaluator] | None	None	Evaluators to score job outputs
parallelism	int (≥1)	1	Number of concurrent jobs
print_results	bool	True	Display progress and results table
description	str | None	None	Optional evaluation description

📊 Orq Platform Integration

Automatic Result Sending

When the ORQ_API_KEY environment variable is set, evaluatorq automatically sends evaluation results to the Orq platform for visualization and analysis.

# Results are automatically sent when ORQ_API_KEY is set
await evaluatorq(
    "my-evaluation",
    data=[...],
    jobs=[...],
    evaluators=[...],
)

What Gets Sent

When the ORQ_API_KEY is set, the following information is sent to Orq:

• Evaluation name
• Dataset ID (when using Orq datasets)
• Job results with outputs and errors
• Evaluator scores with values and explanations
• Execution timing information

Note: Evaluator explanations are included in the data sent to Orq but are not displayed in the terminal output to keep the console clean.

Result Visualization

After successful submission, you'll see a console message with a link to view your results:

📊 View your evaluation results at: <url to the evaluation>

The Orq platform provides:

• Interactive result tables
• Score statistics
• Performance metrics
• Historical comparisons
