DFlash 2: 20% More Tokens from Every Verification Pass
DFlash 2: Keep Drafting Parallel

Inco AI's DFlash 2 upgrades speculative decoding by adding a lightweight path selector and a convolutional fix for suffix decay, boosting output by 16–25% with only ~1% added latency. The selector scores adjacent candidate pairs to pick a coherent path, while convolutions target within-block dependencies that attention neglects. Already integrated into SGLang, vLLM, llama.cpp, and oMLX, DFlash 2 serves Qwen3.8-27B at 2.7–3.4× the throughput of autoregressive decoding.
Choosing is cheaper than predicting.

Watch the video carefully. DFlash2's tool call fails on python syntax.
Usually models in this class nail things like that 1 shot, which the other side did.
I don't know the cause. It may be nothing. But I'd like to see the model doing something where its path is a bit more constrained, to help out rule out such oddities.

But can you just.. not.
Your tech is so good, it speaks for itself. Don't ruin that.

I'm getting around 27 tokens per second decode using vLLM + Qwen 3.8 27b nvfp4 + DFlash 2 on the DGX Spark.
