# No-code Evaluation

This guide will show you how to run evaluations from the UI.

Before you get started, make sure that you have [created a test set](https://docs.agenta.ai/evaluation/create-test-sets) and [configured evaluators](https://docs.agenta.ai/evaluation/configure-evaluators) appropriate for your task.

### Running Evaluations[​](https://docs.agenta.ai/evaluation/no-code-evaluation#running-evaluations) <a href="#running-evaluations" id="running-evaluations"></a>

To start an evaluation, navigate to the Evaluations page and click the `Start new evaluation` button. A modal will appear, allowing you to setup the evaluation.

#### Setting Up Evaluation Parameters[​](https://docs.agenta.ai/evaluation/no-code-evaluation#setting-up-evaluation-parameters) <a href="#setting-up-evaluation-parameters" id="setting-up-evaluation-parameters"></a>

In the modal, specify the following:

* Testset: Choose the testset(s) for your evaluation.
* Variants: Choose one or more variants to evaluate.
* Evaluators: Pick one or more evaluators for assessment.

**Advanced Configuration**[**​**](https://docs.agenta.ai/evaluation/no-code-evaluation#advanced-configuration)

Additional settings allow you to adjust batching and retry parameters for LLM calls. This help mitigating rate limit errors from your LLM provider.

Advanced configuration options include:

* **Batch Size:** Number of test cases to run concurrently in each batch (default: 10).
* **Retry Delay:** Time to wait before retrying a failed call (default: 3s).
* **Max Retries:** Maximum number of retry attempts for a failed call (default: 3).
* **Delay Between Batches:** Pause duration between batch runs (default: 5s).

### Analyzing Evaluation Results[​](https://docs.agenta.ai/evaluation/no-code-evaluation#analyzing-evaluation-results) <a href="#analyzing-evaluation-results" id="analyzing-evaluation-results"></a>

The main view offers an aggregated summary of results. Each column displays the average score per evaluator for each variant/test set combination. You'll also see average latency, total cost, creation date, and evaluation status.

For a detailed view of an evaluation, click on a completed evaluation row.

![Detailed evaluation results](https://docs.agenta.ai/assets/ideal-img/detailed-evaluation-results.0ee7041.1100.png)

The evaluation table columns show inputs, reference answers used by evaluators, LLM application output, evaluator results, cost, and latency.

### Comparing Evaluations[​](https://docs.agenta.ai/evaluation/no-code-evaluation#comparing-evaluations) <a href="#comparing-evaluations" id="comparing-evaluations"></a>

Once evaluations are marked "completed," you can compare two or more evaluations from the same test set. Click the `Compare` button to access the Evaluation comparison view, where you can analyze outputs from multiple evaluations side by side.
