TypeSafe AI raises $870M Series A at $7.5B, led by a16z, for its Jev model

TypeSafe AI says a16z led its $870M Series A at a $7.5B valuation, with Sequoia and DCVC participating. The money backs Jev, which the company calls a "System One" model that hands decisions to code as typed values; it is in early access. TypeSafe claims 1 trillion tokens in three days after launch and 25% of Fortune 500 companies integrating Jev; these figures are the company's own.
