MIT Researchers Accelerate Reasoning-Model Training With TLT
9.2
Relevance Score
MIT and collaborators developed Taming the Long Tail (TLT), an adaptive speculative-decoding system that uses idle processors to train a lightweight drafter during reinforcement-learning rollouts. Tested across multiple reasoning LLMs and presented at the ACM conference, TLT sped training 70–210% while preserving accuracy, reducing compute time and improving energy efficiency for reasoning-model development.
