When you need to generate many text outputs, doing so manually through the app can become cumbersome. Especially if you already know all the prompts you'll be using to build off of. Batch requests automate that process and can speed it up significantly as well.
With batch requests, you choose between 1) a single prompt, 2) no prompt, or 3) upload a CSV file of prompts (one on each line). Finally, you specify how many outputs you want to generate per prompt and set some optional generation settings.
Before you run the request, you'll see an estimate of the maximum number of characters that it might generate based on your settings. When the request is done, you'll get a notification email and can download the outputs in CSV format.
Since the generator can only comprehend a certain length of text at a time, only the last 3000 characters (currently) of each of your prompts will be used. The
prompt column of the output CSV will only show these.
Batch requests can't yet use the topic and keyword controls, which are a new feature only usable from the web interface.
Each request is currently limited to 25 million characters, which is calculated by multiplying (number of prompts) × (outputs per prompt) × (maximum characters per output). For the CSV option, your file must be no larger than 2 GB.
Batch requests use character credits while they run. If a batch request doesn't complete for any reason (e.g. manually canceled, or an error), it will use approximately as many credits as it took to generate the outputs so far.
Each output counts as a minimum of 100 characters, but besides that only what's generated will deduct from your credits.
Batch requests are automatically deleted ("expire") some time after they're created (currently 1 week). You'll need to download the output CSV before then.
Since the text generation is random, it's not guaranteed that every output for a given prompt will be different. As when you generate through the app, it's possible to get similar or identical results. When the outputs are longer, they're more likely to diverge from each other.
