Why isn't LLM reasoning done in vector space instead of natural language?

163 points · 61 comments · r/MachineLearning · by u/ZeusZCC

A discussion about why LLM reasoning is expressed through natural language chain-of-thought rather than explicit vector-based reasoning in latent space. The poster notes that models already operate on high-dimensional vectors internally, so why not have them reason more explicitly in that space? Commenters pointed to existing research on 'looped LLMs' that turn models into RNNs passing latents, and noted that the tradeoff is losing debuggability and control when reasoning is hidden in vectors.

Interesting Points
  • Models already operate on high-dimensional vectors internally, raising questions about why reasoning is surfaced as text
  • Existing research on 'looped LLMs' turns models into RNNs that pass latents
  • The tradeoff of vector-space reasoning is losing debuggability and control for deterministic behavior
  • The actual computation happens in latent space; text reasoning is just a surfaced trace
