How AI training data is priced, and what ours includes

There is no price list, and any vendor who publishes one is hiding the variables. This page shows exactly how a quote is built, what every delivery includes, what costs extra, and how to get a comparable quote from us in two business days.

Three ways to start

Free sample, paid pilot, production programme

Every engagement starts with the sample. Most move to a pilot within two weeks. Pilot fees are credited against production.

Variables

The five things that move a quote

1

Language and variety

Urdu in Karachi is the cheapest thing we field. Brahui in Kalat or Thari Sindhi requires bespoke recruitment and costs several times more per hour.

2

Register and task

Read speech from prompts is fast. Spontaneous two-party conversation, or native-authored multi-turn SFT, takes more contributor time and more QA.

3

Quota strictness

A 50/50 gender split nationwide is easy. Equal cells across four age bands, urban/rural, three dialects and two device classes means rejecting clean audio that lands in a full cell.

4

Annotation depth

Verbatim transcript alone, or transcript plus diarization, noise tags, code-switch spans and a second independent pass. Each layer adds skilled hours.

5

Security tier and speed

Remote annotation is standard. In-VPC, on-prem or secure-facility work, and rush timelines that need parallel teams, carry a premium.

Answers

Questions buyers ask about price

Because the same hour of audio can vary several-fold in cost depending on language rarity, register, quota strictness, transcription depth and QA level. A published number would either mislead you or be padded to cover the worst case. We quote against a written spec instead, within two business days.

Yes. Every catalog dataset has a free, unwatermarked sample pack — typically 2–5 hours of audio, 1–2k text items or around 500 images with full metadata — delivered within one business day with no sales call. It is identical in format and quality to the paid corpus.

A paid pilot: usually 50–200 hours of speech, 25k–100k text items or 10k–50k images in one or two languages, running 3–5 weeks. Pilot fees are credited in full against a production programme.

Per hour of QA-passed audio, inclusive of recruitment, recording, verbatim transcription, metadata, consent artefacts and QA. Rarer languages, spontaneous conversation, strict demographic quotas, diarization and second transcription passes each move the rate up; read speech in Urdu with a single pass sits at the lower end.

Per item: per thousand words for corpora, per prompt–response pair for SFT, per ranked comparison for RLHF, per aligned sentence pair for parallel text. Native authoring costs more than translation and is worth it; see the SFT data quality guide.

Pilots are invoiced on delivery. Programmes are milestone-billed against accepted batches, typically net 30 by international wire, in USD by default or GBP, EUR and AUD on request. Rejected units are never invoiced.

Yes. Standard licences are non-exclusive, perpetual, worldwide and sublicensable for training. Exclusivity for a period or a field of use is available at a premium and is the only thing that changes the licence rather than the delivery.

Send every vendor the same spec: language and variety, hours or items, register, quota axes, acoustic conditions, transcription depth, acceptance test and timeline. Ask each to price the same unit and to state what is excluded. Our buyer's guide to training data cost includes an RFQ template.
