  "title": "TeCoP: Accelerating Diffusion Large Language Model Decoding via Tentative Context Pipelining",
  "summary": "TeCoP replaces the serialized block-wise decoder of diffusion LLMs (LLaDA, Dream) with a training-free staggered block-parallel pipeline that reuses stable but uncommitted predictions as provisional context, committing them via confidence and stability checks in a draft-and-verify loop. It costs implementation complexity in the decoding loop and carries the accuracy risk of committing tokens conditioned on provisional context that later proves wrong, though reported accuracy stays within one point of the original decoder. It can fail on workloads where low-confidence or unstable early predictions propagate errors across blocks, and it applies only to diffusion LLMs, not autoregressive models.",
  "rationale": "The speedup is large, training-free, and fits a single 24GB GPU, but it only benefits teams already serving diffusion LLMs, so its value must be validated against the reader's actual model stack and accuracy tolerance.",
