Abstract
The capabilities of large language models (LLMs) are widely regarded as relying on autoregressive models (ARMs). We challenge this notion by introducing LLaDA, a diffusion model trained from scratch under the pre-training and supervised fine-tuning (SFT) paradigm. LLaDA employs a forward data masking process and a reverse generation process, parameterized by a Transformer to predict masked tokens. It provides a principled generative approach for probabilistic inference by optimizing a likelihood lower bound. Across extensive benchmarks on general tasks, math, code, and so on, LLaDA demonstrates strong scalability and performs comparably to our self-constructed ARM baselines. Remarkably, LLaDA 8B is competitive with strong LLMs like LLaMA3 8B in in-context learning and, after SFT, exhibits impressive instruction-following abilities in case studies such as multi-turn dialogue. Moreover, LLaDA addresses the reversal curse, surpassing GPT-4o in a reversal poem completion task. Our findings show the promise of diffusion models for language modeling at scale and challenge the common assumption that core LLM capabilities discussed above inherently depend on ARMs. Project page and codes: https://ml-gsai.github.io/LLaDA-demo/.

shouting "ENHANCE" repeatedly at a next word predictor gets you much more rounded synthetic intellect scores

Significant progress towards language diffusion models. Reportedly on par with LLaMA3 on many benchmarks. [bsky, 9 points, 2 comments]

- Interesting tid bit, uniformly sampling t then doing coinflips at prob t per step ala LLaDA arxiv.org/abs/2502.09992 is effectively balancing over all possible masks. See bottom of this post from Tim [bsky, 3 points, 1 comments]

- A group of Chinese researchers have developed this model called 'LLaDA' or Large Language Diffusion model. Their 8b parameter model is on par with much larger LLM's.

- Yes ... and this visualization of the diffusion model's "thinking" is perhaps much more honest than the verbalization or inner dialog we see with exposed 01, 03 etc reasoning traces.

- And here is the original paper, published a few weeks ago. It comes with an open-weight 8B model, ready to test on HugginFace. buff.ly/0D00Al1 [bsky, 0 points, 0 comments]
