Episode notes
Reasoning In Latent Space
- Meta's Coconut idea tests letting LLMs reason in their latent hidden states instead of converting every intermediate step to language.
- This mirrors human cognition where some reasoning bypasses language centers and may be more efficient for complex problems.
Thought Tokens Replace Text Steps
- Chain of Continuous Thought represents intermediate steps as model hidden states (thought tokens) instead of text tokens.
- During training they progressively replace language steps with latent state tokens until thoughts are fully continuous.
Mask Loss On Latent Thoughts
- Mask the training loss for question and latent-thought tokens to avoid incentivizing shorter thought sequences.
- Focus optimization on final answer quality rather than compressing intermediate thoughts.
