The paper investigates the scalability and effectiveness of masked diffusion models (MDMs) in core language tasks, such as text generation and language understanding. By establishing a scaling law for MDMs, comparable to autoregressive models (ARMs), it demonstrates that MDMs can be trained with up to 1.1 billion parameters to achieve competitive performance against ARMs of similar sizes. The proposed classifier-free guidance boosts the performance of MDMs in conditional inference tasks, and they outperform ARMs in language understanding on four zero-shot benchmarks. In text generation, MDMs match ARMs’ performance while being faster during sampling. Moreover, MDMs effectively handle bidirectional reasoning and temporal shifts in data, breaking the reverse curse encountered by larger ARMs.

The paper looks at a new type of AI model called masked diffusion models (MDMs). They’re good at language tasks like text generation and understanding sentences. The researchers wanted to see if MDMs could be made even better and used for harder tasks. To do this, they trained many MDMs with different numbers of parameters and compared them to other AI models. They found that the best MDM was almost as good as some bigger AI models, but it used much less computing power. The researchers also showed that MDMs are good at understanding sentences that use math and can even adapt to changing data.
