The differences are shown in the following table: Online prediction Batch prediction Optimized to minimize the latency of serving predictions. Optimized to handle a high volume of instances in a job and to run more complex models. Can process one or more instances per request.

Predictions returned in the response message. Predictions written to output files in a Cloud Storage location that you specify. Input data passed directly as a JSON string. Input data passed indirectly as one or more URIs of files in Cloud Storage locations. Returns as soon as possible. Anyone with Viewer access to the project can request.

Must be a project Editor to run. Runs on the runtime version and in the region selected when you deploy the model. Can run in any available region, using any available runtime version.

Though you should run with the defaults for deployed model versions. Runs models deployed to Cloud ML Engine. Runs models deployed to Cloud ML Engine or models stored in accessible Google Cloud Storage locations.

The needs of your application dictate the type of prediction you should use. Batch prediction latency If you use a simple model and a small set of input instances, you'll find that there is a considerable difference between how long it takes to finish identical prediction requests using online versus batch prediction. Understanding prediction nodes and resource allocation Cloud ML Engine measures the amount of processing you consume for prediction in node hours. Node allocation for batch prediction The batch prediction service scales the number of nodes it uses to minimize the amount of elapsed time your job takes.

To do that, the service: Allocates some nodes to handle your job when you start it. Scales the number of nodes during the job in an attempt to optimize efficiency.

Shuts down the nodes as soon as your job is done. Node allocation for online prediction The online prediction service scales the number of nodes it uses to maximize the number of requests it can handle without introducing too much latency.

To do that, the service: Allocates some nodes the first time you request predictions after a long pause in requests. Scales the number of nodes in response to request traffic, adding nodes when traffic increases, and removing them when there are fewer requests. Limitations of automatic scaling Cloud ML Engine automatic scaling for online prediction can help you serve varying rates of prediction requests while minimizing costs.

Using manual scaling You can affect the scaling of online prediction for a model version by specifying a number of nodes to keep running regardless of traffic. Prediction input data The data you use for getting predictions is new data that takes the same form as the data you used for training.

These formats are summarized in the following table, and described in more detail in the sections below: Prediction type and interface Supported input format Batch with API call Text file with JSON instance strings or TFRecords file (may be compressed) Batch with gcloud tool Text file with JSON instance strings or TFRecords file (may be compressed) Online with API call JSON request message Online with gcloud tool Text file with JSON instance strings or CSV file Instances JSON strings The basic format for both online and batch prediction is a list of instance data tensors.

Individual values in an instance object can be strings, numbers, or lists. The following special formatting is required: Your encoded string must be formatted as a JSON object with a single key named b64. Online prediction input data You pass input instances for online prediction as the message body for the predict request.

Batch prediction input data You provide input data for batch prediction in one or more text files containing rows of JSON instance data as described above.
