D3D: Decoupled Diffusion Drafting for Asynchronous Speculative Decoding
arXiv cs.AI · Published · 3 min read

- What happened
- D3D enables diffusion-based token drafting for language models without waiting for target model hidden states, achieving asynchronous speculative decoding with 5-7x speedup.
- Why it matters
- Matters for engineers optimizing LLM inference latency, particularly when deploying larger models where decoding speed is a bottleneck.
- Watch out
- Results shown on Qwen3 models; generalization to other architectures and whether layer pruning strategy transfers across model families remains unclear.
- speculative
- token
The patterns behind this
- Speculative & Parallel Tool Execution
- Plan-Execute Decoupling (ReWOO/LLMCompiler)
- Latency Optimization
Each one covers how the technique works, when it earns its cost, and where it breaks.
