Why this site exists
AI features can look inexpensive during a prototype and become difficult to forecast once real users, long prompts, retrieval context, and model responses scale together. AICostBudget turns token assumptions into practical cost estimates that non-finance teams can understand.
AICostBudget is not AICosts.ai
AICostBudget (aicostbudget.com) and AICosts.ai are separate products with similar names, and they are not affiliated. AICostBudget is for developers, founders, product teams, and small AI teams planning AI API spend. It publishes source-linked pricing data and free calculators for estimating costs before you choose a model or launch. AICosts.ai describes itself as a cost tracking dashboard built on the provider billing files you upload. AICostBudget does not read your bills or live usage, and it does not send spend alerts.
How the calculators work
The tools use local token estimation and public model pricing data. They do not call OpenAI, Anthropic, Google, DeepSeek, xAI, or any other provider on your behalf. Results are estimates for planning and should be checked against official provider pricing before purchasing or launching.
How pricing data is maintained
Model records keep their provider, billing unit, verification date, and official source link together. The current pricing dataset was last verified on Nov 6, 2026. How we verify When a public source does not expose a confirmed value, the dataset shows it as not listed instead of treating it as zero. You can inspect the source-linked pricing dataset, read how sources are verified, and verify any decision against the provider's official pricing page.
Editorial standards
We aim to explain AI token costs and AI API costs in plain language, separate input and output token pricing, and highlight hidden costs such as retries, embeddings, vector databases, observability, and long-context usage. Planning examples should identify their assumptions and link readers back to the relevant calculator or current source data.
Estimates, corrections, and final billing
AICostBudget calculations are planning estimates, not provider quotes or invoices. Provider pricing, billing rules, discounts, model availability, and account terms can change. The official provider pricing page, billing dashboard, contract, and invoice remain the final source of truth. To report a pricing or content error, follow the corrections policy or use the contact page and include the affected URL plus an official provider source. Do not send API keys or private credentials.
