Two new research papers introduce novel evaluation protocols and architectures for masked diffusion language models (MDLMs). The first paper, "CaRE," proposes a compute-aware framework to standardize evaluations, revealing that factors like temperature and step counts significantly influence reported gains, often reversing previous strategy rankings. The second paper, "PreDiff-LM," presents a hybrid attention mechanism that adapts pretrained autoregressive transformers for bidirectional generation, improving performance on metrics like perplexity and MAUVE compared to standard diffusion models, though still trailing optimized autoregressive models at equal scale.
