Z-Lab releases DFlash-2 for faster LLM generation

By PulseAugur Editorial · [1 sources] ·

Z-Lab has released DFlash-2, an improved technique for accelerating large language model (LLM) generation by predicting upcoming tokens. Unlike its predecessor, DFlash-2 shows notable accuracy and throughput gains, particularly when tested with specific parameter settings. While the underlying mechanism remains similar to the original DFlash, the enhancements in DFlash-2 allow it to outperform the base model in certain scenarios, though support for it is still limited to a few models as of August 2026. AI

IMPACT This technique could lead to faster and more efficient LLM inference, potentially reducing costs and improving user experience.

    DFlash-2: Benchmarking Z-Lab's Successor to DFlash for Accuracy and Throughput Gains

    <p>A while back, we covered DFlash, a draft-token prediction technique that uses a diffusion model. At the time, we tested it on Gemma-4-12b-it-QAT, and the native Assistant model came out ahead — DFlash wasn't able to show a clear advantage.</p> <p>Recently, though, a successor …
