# Find and select a model

List the models available to your credential and choose a calling method based on the task and model capabilities.

## Prerequisites

Prepare a personal access token or service account API Key with Genesis permissions. See [Access credentials](../../../../guides/billing/credentials.md#choose-credential-type) for credential selection and permissions.

## Call sequence

1. [List callable models](../../../../reference/api/genesis/models.md) using the credential you will use for inference. Filter for chat, embedding, or reranking models as needed.
2. Review the candidates' types, capabilities, and prices, and select a model that supports the required calling method.
3. Keep the selected model's calling identifier and continue to the corresponding generation or reranking task.

## API operations

| Task | API operation | When to use it or what to check |
| --- | --- | --- |
| Select an available model | [List callable models](../../../../reference/api/genesis/models.md) | Use the actual inference credential to check model identifiers, capabilities, and prices. |

## Confirm the result

Confirm that the selected model appears in the result for the current credential and supports your task. Use its calling identifier in the model request.

## Limitations and notes

The callable model list is specific to the current credential. Browsing a model catalog does not confirm permission to call a model.
