 ### Output
 
 The response from a successful image generation API call looks like the following example. The `url` field contains a URL where you can download the generated image. The URL stays active for 24 hours.

 The total number of tokens processed in a given request depends on the length of your input, output, and request parameters. The quantity of tokens being processed will also affect your response latency and throughput for the models.

 Azure OpenAI's image processing capabilities with GPT-4o, GPT-4o-mini, and GPT-4 Turbo with Vision models uses image tokenization to determine the total number of tokens consumed by image inputs. The number of tokens consumed is calculated based on two main factors: the level of image detail (low or high) and the image’s dimensions. Here's how token costs are calculated:

         - For GPT-4o and GPT-4 Turbo with Vision, the total token cost is 6 tiles x 170 tokens per tile + 85 base tokens = 1105 tokens.

+GPT-image-1 generates images by first producing specialized image tokens. Both latency and eventual cost are proportional to the number of tokens required to render an image. The number of tokens generated depends on image dimensions and quality:

 Azure OpenAI is a new product offering on Azure. You can get started with Azure OpenAI the same way as any other Azure product where you [create a resource](how-to/create-resource.md), or instance of the service, in your Azure Subscription. You can read more about Azure's [resource management design](/azure/azure-resource-manager/management/overview).
