Questions

Where do the official prices come from?

From each maker's own price page: Anthropic, OpenAI, Google, Z.ai, Qwen (Alibaba), DeepSeek. Each row in the download links to the page its price came from.

How is the Kontinent AI price set?

Each model costs a fixed fraction of its maker's official price, per token. Input, output and cached input use the same fraction, and so does a long-prompt price step where the maker has one.

How current is this data?

It is served live from the same registry the API bills with, so it is current as of 2026-10-30. GET https://api.kontinentai.com/v1/models returns the same prices.

Can I reuse the data?

Yes. The data is under CC BY 4.0: download the CSV or the JSON and reuse it with credit to Kontinent AI and a link to this page.
