Diffusion Language Models

Significant advancements were made in the field of Diffusion Language Models, challenging the traditional dominance of autoregressive models in natural language processing.​

1. LLaDA: A Diffusion-Based Large Language Model

Researchers introduced LLaDA, a diffusion model trained from scratch under the pre-training and supervised fine-tuning (SFT) paradigm. LLaDA models distributions through a forward data masking process and a reverse process, parameterized by a vanilla Transformer to predict masked tokens. By optimizing a likelihood bound, it provides a principled generative approach for probabilistic inference. Across extensive benchmarks, LLaDA demonstrates strong scalability, outperforming self-constructed autoregressive model 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. These findings establish diffusion models as a viable and promising alternative to autoregressive models, challenging the assumption that key LLM capabilities are inherently tied to autoregressive models.

2. Inception Labs' Mercury: The First Commercial-Scale Diffusion LLM

Inception Labs announced Mercury, the first commercial-scale diffusion large language model (dLLM). Mercury is up to 10 times faster than frontier speed-optimized LLMs, running at over 1000 tokens per second on NVIDIA H100s—a speed previously achievable only with custom chips. A code generation model, Mercury Coder, is available for testing in a playground. Inception Labs offers enterprise clients access to code and generalist models via an API and on-premise deployments. This development signifies a paradigm shift in language modeling, leveraging diffusion models to enhance speed and efficiency. ​

These developments underscore the growing potential of diffusion models in natural language processing, offering alternatives to traditional autoregressive approaches with benefits in scalability, speed, and efficiency.
