❯ TypeSafe says three-week-old Jev is used by about a quarter of the Fortune 500 and handles over a trillion tokens a day

Two numbers from the CEOTypeSafe CEO Diogo Almeida told The Wall Street Journal that the company’s model Jev is in use by about 25% of Fortune 500 companies, and that “we were at a trillion tokens per day about a week ago.” Jev was released only on September 15. The figures are the company’s own, have not been verified by a third party, and the definition of “in use” was not given.

Numbers, not wordsJev differs from familiar large language models. It does not generate text and returns only numbers. Asked a yes-or-no question, it gives a confidence score between 0 and 1. Asked a multiple-choice question, it gives a probability for each option. By its own description, it is mainly used for classification, routing and guardrails. It charges $0.042 per million input tokens and nothing for output.

Traffic that comes from machinesAlmeida calls the traffic “non-fleeting” because servers, not people, make the calls. TypeSafe was founded by Almeida, formerly of OpenAI, and two co-founders, and announced a $40 million seed round led by DCVC when it emerged on September 15. On October 1, Cloudflare released its open-weight Clef models with a Jev-compatible interface, so companies can swap them in without rewriting calling code.

A substitute within three weeksCompanies adopt Jev because much back-end judgment does not need a model that can write essays, and cheap and fast matter more. Switching costs for such models are also low, and Cloudflare’s compatible product means TypeSafe will soon compete directly on price and accuracy.
