arXiv:2605.07013v2 Announce Type: replace Abstract: Diffusion language models (DLMs) promise parallel, order-agnostic generation, but on standard benchmarks they have historically lagged behind autoregressive models in sample quality and diversity. Recent continuous flow and diffusion approaches have narrowed this gap. In this work, we further close the autoregressive gap by modeling text as a continuous diffusion process over fixed-width binary bitstreams. We refer to the resulting model as CoBit (Continuous Bitstream Diffusion). Our approach represents semantic tokens as analog bit sequences
Ongoing research in language model architectures is constantly seeking to improve performance and efficiency, pushing the boundaries of existing paradigms like autoregressive models.
This development represents a significant step towards closing the performance gap between diffusion models and autoregressive models for language generation, potentially enabling new, more efficient approaches.
The ability of diffusion models to achieve sample quality and diversity comparable to autoregressive models, especially with parallel and order-agnostic generation, fundamentally changes how large language models can be built and deployed.
