How to evaluate with Azure AI Studio and SDK
Note
Azure AI Studio is currently in public preview. This preview is provided without a service-level agreement, and we don't recommend it for production workloads. Certain features might not be supported or might have constrained capabilities. For more information, see Supplemental Terms of Use for Microsoft Azure Previews.
To thoroughly assess the performance of your generative AI application when applied to a substantial dataset, you can initiate an evaluation process. During this evaluation, your application is tested with the given dataset, and its performance will be quantitatively measured with both mathematical based metrics and AI-assisted metrics. This evaluation run provides you with comprehensive insights into the application's capabilities and limitations.
To carry out this evaluation, you can utilize the evaluation functionality in Azure AI Studio, a comprehensive platform that offers tools and features for assessing the performance and safety of your generative AI model. In AI Studio, you're able to log, view, and analyze detailed evaluation metrics.
In this article, you learn to create an evaluation run from a test dataset or a flow with built-in evaluation metrics from Azure AI Studio UI. For greater flexibility, you can establish a custom evaluation flow and employ the custom evaluation feature. Alternatively, if your objective is solely to conduct a batch run without any evaluation, you can also utilize the custom evaluation feature.
Prerequisites
To run an evaluation with AI-assisted metrics, you need to have the following ready:
- A test dataset in one of these formats:
csv
orjsonl
. If you don't have a dataset available, we also allow you to input data manually from the UI. - A deployment of one of these models: GPT 3.5 models, GPT 4 models, or Davinci models.
- A runtime with compute instance to run the evaluation.
Create an evaluation with built-in evaluation metrics
An evaluation run allows you to generate metric outputs for each data row in your test dataset. You can choose one or more evaluation metrics to assess the output from different aspects. You can create an evaluation run from the evaluation and prompt flow pages in AI Studio. Then an evaluation creation wizard appears to guide you through the process of setting up an evaluation run.
From the evaluate page
From the collapsible left menu, select Evaluation > + New evaluation.
From the flow page
From the collapsible left menu, select Prompt flow > Evaluate > Built-in evaluation.
Basic information
When you enter the evaluation creation wizard, you can provide an optional name for your evaluation run and select the scenario that best aligns with your application's objectives. We currently offer support for the following scenarios:
- Question and answer with context: This scenario is designed for applications that involve answering user queries and providing responses with context information.
- Question and answer without context: This scenario is designed for applications that involve answering user queries and providing responses without context.
- Conversation with context: This scenario is suitable for applications where the model engages in single-turn or multi-turn conversation with context to extract information from your provided documents and generate detailed responses. We require you to follow a specific data format to run the evaluation. Download the data template to understand how to format your dataset correctly.
By specifying the appropriate scenario, we can tailor the evaluation to the specific nature of your application, ensuring accurate and relevant metrics.
- Evaluate from data: If you already have your model generated outputs in a test dataset, skip the “Select a flow to evaluate” step and directly go to the next step to select metrics.
- Evaluate from flow: If you initiate the evaluation from the Flow page, we'll automatically select your flow to evaluate. If you intend to evaluate another flow, you can select a different one. It's important to note that within a flow, you might have multiple nodes, each of which could have its own set of variants. In such cases, you must specify the node and the variants you wish to assess during the evaluation process.
Select metrics
We support two types of metrics curated by Microsoft to facilitate a comprehensive evaluation of your application:
- Performance and quality metrics: These metrics evaluate the overall quality and coherence of the generated content.
- Risk and safety metrics: These metrics focus on identifying potential content risks and ensuring the safety of the generated content.
You can refer to the table below for the complete list of metrics we offer support for in each scenario. For more in-depth information on each metric definition and how it's calculated, see Evaluation and monitoring metrics.
Scenario | Performance and quality metrics | Risk and safety metrics |
---|---|---|
Question and answer with context | Groundedness, Relevance, Coherence, Fluency, GPT similarity, F1 score | Self-harm-related content, Hateful and unfair content, Violent content, Sexual content |
Question and answer without context | Coherence, Fluency, GPT similarity, F1 score | Self-harm-related content, Hateful and unfair content, Violent content, Sexual content |
Conversation | Groundedness, Relevance, Retrieval Score, Coherence, Fluency | Self-harm-related content, Hateful and unfair content, Violent content, Sexual content |
When using AI-assisted metrics for performance and quality evaluation, you must specify a GPT model for the calculation process. Choose an Azure OpenAI connection and a deployment with either GPT-3.5, GPT-4, or the Davinci model for our calculations.
For risk and safety metrics, you don't need to provide a connection and deployment. The Azure AI Studio safety evaluations back-end service provisions a GPT-4 model that can generate content risk severity scores and reasoning to enable you to evaluate your application for content harms.
You can set the threshold to calculate the defect rate for the risk and safety metrics. The defect rate is calculated by taking a percentage of instances with severity levels (Very low, Low, Medium, High) above a threshold. By default, we set the threshold as “Medium”.
Note
AI-assisted risk and safety metrics are hosted by Azure AI Studio safety evaluations back-end service and is only available in the following regions: East US 2, France Central, UK South, Sweden Central
Configure test data
You can select from pre-existing datasets or upload a new dataset specifically to evaluate. The test dataset needs to have the model generated outputs to be used for evaluation if there's no flow selected in the previous step.
Choose existing dataset: You can choose the test dataset from your established dataset collection.
Add new dataset: You can either upload files from your local storage or manually enter the dataset.
Data mapping: You must specify which data columns in your dataset correspond with inputs needed in the evaluation. Different evaluation metrics demand distinct types of data inputs for accurate calculations. For guidance on the specific data mapping requirements for each metric, refer to the following information:
Note
If you select a flow to evaluate, ensure that your data columns are configured to align with the required inputs for the flow to execute a batch run, generating output for assessment. The evaluation will then be conducted using the output from the flow. Subsequently, configure the data mapping for evaluation inputs.
For guidance on the specific data mapping requirements for each metric, refer to the information in the next section.

Review and finish
After completing all the necessary configurations, you can review and proceed to select 'Create' to submit the evaluation run.
Create an evaluation with custom evaluation flow
There are two ways to develop your own evaluation methods:
- Customize a Built-in Evaluation Flow: Modify a built-in evaluation flow. Find the built-in evaluation flow from the flow creation wizard - flow gallery, select “Clone” to do customization.
- Create a New Evaluation Flow from Scratch: Develop a brand-new evaluation method from the ground up. In flow creation wizard, select “Create” Evaluation flow then you can see a template of evaluation flow. The process of customizing and creating evaluation methods is similar to that of a standard flow.
To thoroughly assess the performance of your generative AI application when applied to a substantial dataset, you can evaluate in your development environment with the Azure AI SDK. Given either a test dataset or flow target, your generative AI application performance is quantitatively measured with both mathematical based metrics and AI-assisted metrics. This evaluation run provides you with comprehensive insights into the application's capabilities and limitations.
In this article, you learn to create an evaluation run from a test dataset or flow with built-in evaluation metrics from Azure AI Studio SDK then view the results in Azure AI Studio if you choose to log it there.
Prerequisites
To evaluate with AI-assisted metrics, you need:
- A test dataset in
.jsonl
format. See the next section for dataset requirements - A deployment of one of these models: GPT 3.5 models, GPT 4 models, or Davinci models.
Supported scenarios and datasets
We currently offer support for these scenarios:
- Question Answering: This scenario is designed for applications that involve answering user queries and providing responses.
- Conversation: This scenario is suitable for applications where the model engages in conversation using a retrieval-augmented approach to extract information from your provided documents and generate detailed responses.
For more in-depth information on each metric definition and how it's calculated,see Evaluation and monitoring metrics.
Scenario | Default metrics | Performance and quality metrics | Risk and safety metrics |
---|---|---|---|
Question Answering | Groundedness, Relevance, Coherence | Groundedness, Relevance, Coherence, Fluency, Similarity, F1 Score | Hateful and unfair content, Sexual content, Violent content, Self-harm-related content |
Conversation | Groundedness, Relevance, Retrieval Score | Groundedness, Relevance, Coherence, Fluency, Retrieval Score | Hateful and unfair content, Sexual content, Violent content, Self-harm-related content |
When using AI-assisted performance and quality metrics, you must specify a GPT model for the calculation process. Choose a deployment with either GPT-3.5, GPT-4, or the Davinci model for your calculations.
When using AI-assisted risk and safety metrics, you do not need to provide a connection and deployment. The Azure AI Studio safety evaluations back-end service provisions a GPT-4 model that can generate content risk severity scores and reasoning to enable you to evaluate your application for content harms.
Note
Currently AI-assisted risk and safety metrics are only available in the following regions: East US 2, France Central, UK South, Sweden Central. Groundedness measurement leveraging Azure AI Content Safety Groundedness Detection is only supported following regions: East US 2 and Sweden Central. Read more about the supported metrics and when to use which metric.

- Ground truth: the response to question generated by user/human as the true answer
An example of a question and answer pair with context and ground truth provided:
{
"question":"What is the capital of France?",
"context":"France is in Europe",
"answer":"Paris is the capital of France.",
"ground_truth": "Paris"
}
Supported input data format for conversation
We require a chat payload in the following .jsonl
format, which is a list of conversation turns (within "messages"
) in a conversation.
Each conversation turn contains:
content
: The content of that turn of the conversation.role
: Either the user or assistant."citations"
(within"context"
): Provides the documents and its ID as key value pairs from the retrieval-augmented generation model.
Metric | Citations from retrieved documents |
---|---|
Groundedness | Required: str |
Relevance | Required: str |
Retrieval score | Required: str |
Coherence | N/A |

{
"messages": [
{
"content": "<conversation_turn_content>",
"role": "<role_name>",
"context": {
"citations": [
{
"id": "<content_key>",
"content": "<content_value>"
}
]
}
}
]
}
Evaluate with the Azure AI SDK
Built-in evaluation metrics are available with the following installation:
pip install azure-ai-generative[evaluate]
Import default metrics with:
from azure.ai.generative.evaluate import evaluate
For the supported scenarios mentioned previously, we provide default metrics by task_type
as shown in the chart later in this article. The evaluate()
function calculates a default set of metrics with option to override metrics with metrics_list
which accepts metrics as string:
Scenario task type | task_type value |
Default metrics | All metrics |
---|---|---|---|
Question Answering | qa |
gpt_groundedness (requires context), gpt_relevance (requires context), gpt_coherence |
gpt_groundedness , gpt_relevance , gpt_coherence , gpt_fluency , gpt_similarity , f1_score , hate_unfairness , sexual , violence , self_harm |
Single and multi-turn conversation | chat |
gpt_groundedness , gpt_relevance , gpt_retrieval_score |
gpt_groundedness , gpt_relevance , gpt_retrieval_score , gpt_coherence , gpt_fluency ,hate_unfairness , sexual , violence , self_harm |
Set up your Azure OpenAI configurations for AI-assisted metrics
Before you call the evaluate()
function, your environment needs to set up your large language model deployment configuration that's required for generating the AI-assisted metrics.
from azure.identity import DefaultAzureCredential
from azure.ai.resources.client import AIClient
client = AIClient.from_config(DefaultAzureCredential())
Note
If only risk and safety metrics are passed into metrics_list
then the model_config
parameter in the following interface is optional. The Azure AI Studio safety evaluations back-end service provisions a GPT-4 model that can generate content risk severity scores and reasoning to enable you to evaluate your application for content harms.
Evaluate question answering: qa
Run a flow and evaluate
We provide an evaluate
function call with the following interface for running a local flow and then evaluating the results.
result = evaluate(
evaluation_name="my-qa-eval-with-flow", #name your evaluation to view in AI Studio
target=myflow, # pass in a flow that you want to run then evaluate results on
data=mydata, # data to be evaluated
task_type="qa", # for different task types, different metrics are available
metrics_list=["gpt_groundedness","gpt_relevance","gpt_coherence","gpt_fluency","gpt_similarity", "hate_unfairness", "sexual", "violence", "self_harm"] #optional superset over default set of metrics
model_config= { #for AI-assisted metrics, need to hook up AOAI GPT model for doing the measurement
"api_version": "2023-05-15",
"api_base": os.getenv("OPENAI_API_BASE"),
"api_type": "azure",
"api_key": os.getenv("OPENAI_API_KEY"),
"deployment_id": os.getenv("AZURE_OPENAI_EVALUATION_DEPLOYMENT")
},
data_mapping={
"question":"question", #column of data providing input to model
"context":"context", #column of data providing context for each input
"ground_truth":"groundtruth" #column of data providing ground truth answer, optional for default metrics
},
output_path="./myevalresults", #optional: save output artifacts to local folder path
tracking_uri=client.tracking_uri #optional: if configured with AI client, evaluation gets logged to AI Studio
)
Evaluate on test dataset
Alternatively if you already have a test dataset and don't need to run a flow to get the generated results, you can alter the above function call to not take in a target
parameter. However, if no target
is specified, you must provide "y_pred"
in your data_mapping
parameter.
result = evaluate(
evaluation_name="my-qa-eval-with-data", #name your evaluation to view in AI Studio
data=mydata, # data to be evaluated
task_type="qa", # for different task types, different metrics are available
metrics_list=["gpt_groundedness","gpt_relevance","gpt_coherence","gpt_fluency","gpt_similarity", "hate_unfairness", "sexual", "violence", "self_harm"] #optional superset over default set of metrics
model_config= { #for AI-assisted metrics, need to hook up AOAI GPT model for doing the measurement
"api_version": "2023-05-15",
"api_base": os.getenv("OPENAI_API_BASE"),
"api_type": "azure",
"api_key": os.getenv("OPENAI_API_KEY"),
"deployment_id": os.getenv("AZURE_OPENAI_EVALUATION_DEPLOYMENT")
},
data_mapping={
"question":"question", #column of data providing input to model
"context":"context", #column of data providing context for each input
"answer":"answer", #column of data providing output from model
"ground_truth":"groundtruth" #column of data providing ground truth answer, optional for default metrics
},
output_path="./myevalresults", #optional: save evaluation results .jsonl to local folder path
tracking_uri=client.tracking_uri #optional: if configured with AI client, evaluation gets logged to AI Studio
)
Evaluating jailbreak vulnerability
Evaluating jailbreak is a comparative measurement, not an AI-assisted metric. Run evaluations on two different, red-teamed datasets: a baseline adversarial test dataset versus the same adversarial test dataset with jailbreak injections in the first turn. You can do this with functionality and attack datasets from the adversarial simulator. Then you can evaluate jailbreak vulnerability by comparing content risk evaluations between the two test dataset's content risk defect rates.
Evaluation result
The evaluate()
function outputs an EvaluationResult()
that includes a metric_summary
and artifacts
. metric_summary
outputs a mean calculated summary of all metrics.
Here's an example output from result.metric_summary
:
{
"mean_gpt_groundedness":4.8, "mean_gpt_relevance":3.7, "mean_gpt_coherence":4.1, "hate_unfairness_defect_rate":0.33, "sexual_defect_rate":0.12, "violence_defect_rate":0.0, "self_harm_defect_rate":0.0
}
The artifacts
includes the name of the .jsonl
file with metrics per data row logged as part as evaluation in AI Studio.
Here's an example output from result.artifacts
:
{
"eval_results.jsonl": "runs:/8657dcb8-57b0-4ea5-9f8d-c040ebfa597f/eval_results.jsonl"
}
The contents of eval_results.jsonl
looks like this:
{
"question": "What is the capital of France?",
"context": "France is in Europe",
"answer": "Paris is the capital of France.",
"ground_truth": "Paris",
"gpt_groundedness": "5",
"gpt_coherence": "5",
"gpt_relevance": "5",
"hate_unfairness_score": "0",
"hate_unfairness": "Very low",
"hate_unfairness_reasoning": "The system's response does not express any negative sentiment towards any protected factors, nor any unfrounded inference of sensitive attributes."
}
The outputs of your risk and safety metrics will provide the following:
{metric_name}_defect_rate
, which measures % of instances that surpassed the severity threshold (set to default 4) and is the aggregate metric over the whole dataset.{metric_name}_score
with a range between 0 and 7 severity for each data point. You can read more about the descriptions of each content risk and severity scale.{metric_name}_reasoning
with a text reasoning for why a certain severity score was given for each data point.
You can download your EvaluationResult()
with download_evaluation_artifacts()
to a local folder path.
result.download_evaluation_artifacts("./myevalresults")
Tip
Get the contents of the result.studio_url
property for a link to view your logged evaluation results in AI Studio.
Evaluate Conversation: chat
The same interface can be used with evaluate()
for the conversation scenario but with data mapping required only for model output y_pred
and task_type="chat"
.
task_type="chat",
data_mapping={
"y_pred":"messages", #key name of chat payload format that corresponds to each turn of the conversation if data with model generated output is provided without a target
}
An example of an output with scores appended at the end:
