Article summary
Quick briefing — cleaned from the original RSS feed
How DFlash Uses Block Diffusion to Break the Speculative Decoding Bottleneck Autoregressive LLM inference has a fundamental problem: every token depends on the one before it. Even with speculative decoding — where a small draft model proposes tokens and the target model verifies them in parallel — the drafting step itself has remained sequential. DFlash, a framework from researchers at UC San Diego's Z Lab, changes that by replacing the autoregressive drafter with a block diffusion model that…
