Is this old already? Not saying that's a bad thing, since it seems very sophisticated. Just curious if there's an update

It's clearly a typo on the year, April 12 was two days ago, a quick check in HuggingFace shows that they were uploaded 5 days ago.

Can diffusion models have reasoning steps where they generate a block, introspect and then generate another until the output is satisfactory?

Well, you can take the output of a first pass and pass it back through the model like AR “reasoning” models do at inference time.

Yes and has this been tried?

If I’m reading this right, this is pretty wild. They turned a Qwen autoregressor into a diffuser by using a bunch of really clever techniques, and they vastly outperform any “native diffuser,” actually being competitive with the base model they were trained from. The obvious upside here is the massive speedup in generation. And then through a LoRA adapter, you can ground the diffuser on the base model’s distribution…

I don't understand how you can compare against the base model output without generating with the base model, in which case what's the point?

Is anyone here experimenting seriously with Diffusion for text generation? I’d love to learn about your experiences!

It's being explored right now for speculative decoding in the local-LLM space, which I think is quite interesting as a use-case https://www.emergentmind.com/topics/dflash-block-diffusion-f...

DFlash immediately came to my mind.

There are several Mac implementations of it that show > 2x faster Qwen3.5 already.

You would only use the base model during training. This is a distillation technique

I think your excitement is justified. The paper is claiming a serious bridge between AR quality and parallel decoding, and the lossless LoRA-assisted mode is the wildest part.
