TypeSafe AI, maker of the decision model Jev, raises $870 million at a $7.5 billion valuation

TypeSafe AI, the developer of the Jev model, has raised $870 million at a $7.5 billion valuation, TechCrunch reports. Andreessen Horowitz led the round, with participation from Sequoia and existing investor DCVC. Jev launched on September 15 and spread quickly. TypeSafe says a third of Fortune 500 companies already use it, though that figure comes from the company. Jev is built on a transformer architecture but is not a large language model. Instead of text, it outputs probabilities, which the company calls 'calibrated decisions.' TypeSafe says the model is much faster and uses far fewer tokens than LLMs, and it markets Jev for automating tasks rather than generating text or code. 'We have been super good at human language for four years, but it's not useful for automation because computers speak a different language,' co-founder Diogo Almeida, a former OpenAI researcher, told TechCrunch. TypeSafe was founded in 2024 by Almeida, former Meta research engineer Sasha Sheng and others. The round shows that investors are willing to back AI models built for business automation rather than text generation.
