Meta’s breakthrough lets language models think in continuous concepts instead of discrete words with zero computational overhead
Current AI models think by choosing words. One word at a time. Like you’re navigating a maze by writing down every single turn.
Researchers at Meta FAIR have introduced a groundbreaking method that enables language models to reason using continuous concept spaces rather than relying solely on discrete tokens. This innovative approach, detailed in their paper “Soft Tokens, Hard Truths,” demonstrates significant advantages, such as improved diversity in reasoning, stronger generalization, and computational efficiency, all while allowing for a more natural exploration of ideas akin to human thought processes.
