About

Built and maintained by Jaehyun Jeon.

computetrail is an independent project that tracks the price of large language model APIs over time. Most comparison sites show only today's pricing; we keep a daily record so you can answer questions like "has this model gotten cheaper since launch?" and "which provider keeps cutting prices?".

Who runs it

computetrail is built and maintained by Jaehyun Jeon, an engineer who works with LLM APIs directly — the kind of person who has to answer "what will this actually cost per month?" before shipping a feature.

The site exists because that question was annoyingly hard to answer. Provider pricing pages show today's number and nothing else; when a price changes, the old one simply disappears. There was no way to ask "has this model gotten cheaper since launch?" or "which provider keeps quietly repricing?" — because nobody was keeping the receipts. So I started keeping them: one price snapshot every day, stored and never back-filled, for every model I could track.

Everything here — the daily collector, the price histories, the comparisons andguides — is run by one person, independently, with no affiliation to or sponsorship from any model provider.
