About this product

Choosing an AI model is now a cost decision as much as a quality one. Prices differ by more than 50 times between models, caching and batch discounts change the picture, and some prices are promotional or change on a set date. This workbook turns that into numbers for your own workloads. Describe your jobs once: runs a month, model calls per run, tokens in and out, how much input is cached, and whether it can wait for batch processing. See each job's monthly cost on 17 models from Anthropic, OpenAI, Google, Moonshot AI (Kimi) and Z.ai (GLM). Route each job to the cheapest model at or above the capability tier you set, and see the saving against the model you would otherwise use for everything. Totals come monthly and yearly, in USD and your currency, by job and by vendor, with a chart. Every price was read on the vendor's own pricing page, with the page and date on every row. Dated changes are built in: Gemini 3.8 Flash's price doubles on 1 January 2027, and the workbook switches automatically. Edit any price or add your own models; nothing is locked. It compares prices, not quality: the capability tier is yours to set from your own tests, and it comes pre-filled from price bands only. It does not include cache writes and storage, long-context surcharges, web search, images, audio, taxes or regional uplifts. Not financial advice.

Questions

How were the prices and results checked?

A script checked every model's input, cached and output price against the saved text of the vendor's official page (17 of 17), and a planted wrong price was caught. The workbook was opened in Microsoft Excel (Microsoft 365), fully recalculated and compared with a separate calculation in Python: 99 of 99 checks passed, with no error cells. A deliberately broken formula was caught by 20 checks. The workbook in the download is byte-identical to the one tested.

Will the prices stay right?

No price list does. The prices are dated 21 September 2026 and vendors change them often, so refresh them every 1–2 months from the vendor pages listed on each row. Any price can be edited.

Is it affiliated with the AI vendors?

No. It is not affiliated with, endorsed by or sponsored by Anthropic, OpenAI, Google, Moonshot AI or Z.ai. Model names are used only to identify the products priced.
