## Loading the model
4244

43-
To load the model, use the `load` method. It accepts the `modelSource` which is a string that specifies the location of the model binary. For more information, take a look at [loading models](../fundamentals/loading-models.md) page. This method returns a promise, which can resolve to an error or void.

To load the model, create a new instance of the module and use the `load` method on it. It accepts the `modelSource` which is a string that specifies the location of the model binary. For more information, take a look at [loading models](../fundamentals/loading-models.md) page. This method returns a promise, which can resolve to an error or void.

## Running the model

To run the model, you can use the `forward` method. It accepts one argument, which is the image. The image can be a remote URL, a local file URI, or a base64-encoded image. The method returns a promise, which can resolve either to an error or an object containing categories with their probabilities.

To run the model, you can use the `forward` method on the module object. It accepts one argument, which is the image. The image can be a remote URL, a local file URI, or a base64-encoded image. The method returns a promise, which can resolve either to an error or an object containing categories with their probabilities.

## Managing memory
52+
53+
The module is a regular JavaScript object, and as such its lifespan will be managed by the garbage collector. In most cases this should be enough, and you should not worry about freeing the memory of the module yourself, but in some cases you may want to release the memory occupied by the module before the garbage collector steps in. In this case use the method `delete()` on the module object you will no longer use, and want to remove from the memory. Note that you cannot use `forward` after `delete` unless you load the module again.
