What drives invoice parsing cost

Invoices are short, highly repetitive documents processed in bulk: the ideal batch API workload. Per-document cost is low; total cost is set by volume and by whether you are paying full rate for a job that could have run asynchronously overnight at a discount. The extraction schema is constant, so it should never be paying full input rate either.

For Gemini 3.8 Flash specifically, that means output tokens cost 5.0x more than input, at $3.75 vs $0.75 per MTok. At this use case’s 2,000/600 token split, output accounts for 60% of the $0.003750 per-call cost.

Prompt caching: 90% off input tokens

Caching drops input cost from $0.75 to $0.08/MTok. For repeated system prompts, that saves $0.001350 per call.

Batch API: 50% off all tokens

Submit requests asynchronously and receive 50% off all token costs. This works best for offline pipelines where latency requirements are flexible.
