What this site is
LLMomics is an independent reference for Claude API prices. We publish list prices, the date we read them, and a link to the Anthropic page each figure came from. We are not affiliated with Anthropic, OpenAI, Google or any other provider, and nothing here is advice about what to buy.
Accuracy, and where it stops
The numbers are checked by hand. We publish a price only if we have opened the source page for it; where we can't, the cell stays empty on purpose. Even so, a price can move between our check and your read, and the estimate boxes on the token cost page work from a characters-per-token rule of thumb, not from a tokenizer.
For anything with money on it — a batch job you're sizing, a context limit you're testing — use Anthropic's published page and its count_tokens endpoint, not this site.
No warranty
This site is provided as it is. We don't promise it will be available, error-free or up to date at the moment you read it, and we're not liable for decisions made from it.
Links to other people's pages
Most outbound links here exist to show where a number came from. Those pages belong to someone else, they can change without telling us, and we're not responsible for what's on them.
Quoting us
The text, tables and layout on this site are ours. Quote a figure, cite the page, link to it — that's welcome, and mostly the point. Don't republish the page wholesale as your own.
Changes, and how to reach us
