When batch processing saves 50% over realtime API.
Every number on aicost.ai is verified by 11 independent audit layers that run every day at 03:30 EDT — covering structural integrity, math correctness, source-side freshness, and cross-source agreement. We publish today's snapshot date and per-vendor verification timestamps below so you can verify any number yourself.
All 8 layers must pass before any pricing data is considered fresh. The infrastructure runs daily and publishes results to an internal dashboard. If any layer flags an issue, it is treated as stop-the-line work.
Every value falls into one of five categories. Numbers without an asterisk are vendor-published, directly observable, or computed by arithmetic on published data. Numbers marked with * are typical best-target values — we state the working range and invite you to override with your own number.
Any individual claim may also be tagged with * if its source has not yet been re-verified against the current vendor page — treat such claims as approximate until the next verification cycle resolves them.
Each vendor's pricing page is independently re-checked on a cadence ranging from daily to weekly. Below: when each relevant vendor was last verified by our automated pipeline.
Directly from the vendor's own docs. See per-vendor verification dates in the panel above.
“All usage is charged at 50% of the standard API prices.”
Applies to all models supported by the Message Batches API.
“with most batches finishing in less than 1 hour while reducing costs by 50% and increasing throughput.”
Standard processing time for most batches; some may take longer due to demand or request volume.
“Amazon Bedrock offers select foundation models (FMs) from leading AI providers like Anthropic, Meta, Mistral AI, and Amazon for batch inference at a 50% lower price compared to on-demand inference pricing.”
Applies to all supported foundation models for batch inference; Flex tier also offers 50% discount.
“Batch API (50% cost reduction)”
The vendor explicitly states a 50% cost reduction for Batch API compared to realtime API.
“Batching allows you to run asynchronous inference on large inputs in parallel, reducing compute costs while running large workloads at a 50% discount.”
Applies to all batch jobs; discount is applied to the base real-time inference cost.
“The Batch API offers a straightforward set of endpoints that allow you to collect a set of requests into a single file, kick off a batch processing job to execute these requests, query for the status of that batch while the underlying requests execute, and eventually retrieve the collected results when the batch is complete. Compared to using standard endpoints directly, Batch API has: 1. **Better cost efficiency:** 50% cost discount compared to synchronous APIs”
Discount applies to all Batch API endpoints relative to their synchronous counterparts.
“Fast completion times: Each batch completes within 24 hours (and often more quickly)”
Completion window is fixed at 24 hours for all batches.
“Google Cloud's pay-as-you-go pricing offers automatic savings based on monthly usage and discounted rates for prepaid resources.”
Discount applies to prepaid resources; batch inference is a form of prepaid resource usage.
“Context caching price ... $0.15$1.00 / 1,000,000 tokens per hour (storage price)”
Explicit caching storage fee applies to cached tokens; read rate is not explicitly stated as a fraction of base input rate. Storage fee is billed per hour per 1M cached tokens.
“Context caching price ... $0.15$1.00 / 1,000,000 tokens per hour (storage price)”
The storage fee is explicitly stated as $1.00 per 1,000,000 tokens per hour. The $0.15 appears to be a discounted rate for certain tiers or conditions not specified in the quote.
All vendor-published prices used by this calculator are sourced from the pages below. See the verification panel above for when each was last re-checked.
We treat methodology as a living document. If a price is wrong, a benchmark is outdated, or you have a better citation, let us know and we will verify within 48 hours.

10 of 10
vendors are currently verified. Aggregator services (TokenCost, AI Pricing Guru, etc.)
are not listed.
Derived from industry conventions, not directly published by the vendor. Typical conventions: cached input = 10% of base (90% off), Batch API = 50% of base (50% off).
