OpenAI Batch API savings calculator
OpenAI's Batch API charges 50% less than standard rates for the same input and output tokens on supported models. Jobs run asynchronously (typically within 24 hours) — ideal for enrichment, classification, and backfills — not for live chat.
Standard token rates last updated: April 2026. Discount per OpenAI's published Batch pricing.
Workload (same for both)
Batch pricing assumes the model is available on Batch — confirm in OpenAI docs for your model.
Estimated monthly API cost
Standard (sync)
$562.50
Chat Completions–style billing
Batch API (async)
$281.25
50% off token rates
You'd save about $281.25 / month (50%)
Annualized: ~$3,375.00 — if this workload is actually batchable (latency-tolerant).
When Batch is wrong
User-facing chat, low-latency tools, and anything that needs a response in seconds should stay on standard endpoints. Use Batch for jobs you can queue overnight or over a few hours.
