Researchers are developing new methods to accelerate large language model (LLM) inference, a process often slowed by sequential decoding. Several recent papers explore speculative decoding techniques that use a smaller "draft" model to propose tokens, which are then verified by a larger "target" model. Innovations include combining multi-draft and block verification strategies, leveraging KV caches for richer drafting signals, and developing training-free methods that accept semantically correct but not exact matches. These approaches aim to significantly increase decoding speed while maintaining output quality and generalization across different models and tasks. AI
