<a name="batch-inference-job-output-examples"></a>

When you create a batch inference job, the job imports your batch input data from an Amazon S3 bucket, uses your solution version to generate *item recommendations*, and exports the recommendations to an Amazon S3 bucket in JSON format. 

The following sections list output file examples for batch inference jobs by recipe type. You can't get batch recommendations with the Trending-Now or Next-Best-Action recipes.
