Market landscapes / Model Development

Foundation Model Labs companies

The labs training frontier and near-frontier models. Anthropic, Cohere, AI21 Labs and others. It is a small field for the amount of attention it takes up, and three quarters of it is hiring right now. Only 1 of the 32 has been acquired, which in a field this valuable says more about what these companies cost than about anyone's appetite.
