Frequently asked questions

What does this calculator estimate?

It estimates the all-in cost to produce synthetic data for AI agents: generation (LLM API, managed platform, or local GPU), filtering/retry waste, human validation, storage, setup, and ongoing maintenance.

Which generation approach should I pick?

Use LLM API for unstructured text, QA pairs, dialogues, and agent trajectories. Use managed platforms for tabular/relational privacy-safe datasets. Use local GPU for high-volume or sensitive workloads.

How is the filter rate used?

Some generated records fail quality checks or schema validation and must be regenerated. The filter rate models how many extra records need to be generated to hit your target usable count.

Does storage cost matter?

For small text datasets it is usually negligible. For high-volume or long-retention datasets (especially tabular or embedded data), storage can add hundreds of dollars per year.

What is the difference between review rate and validator?

The validator preset sets the per-record validation cost and throughput. The review rate is the percentage of records you actually send through that validation step. Set review rate to 0 if you rely only on automated filters.

How do I reduce synthetic-data cost?

Shorten prompts, reduce output tokens, use a smaller model for first-pass generation, filter aggressively, spot-check instead of full human review, and delete old datasets once they are no longer needed.

Synthetic data costs blend LLM generation tokens, structured/tabular synthesis platforms, storage, filtering/retry compute, and human validation labor. Replace defaults with quotes from your chosen provider. Treat results as directional budgets, not invoices.
