The author demonstrates this by fine-tuning RoBERTa with variable masking rates to perform text generation through iterative denoising, similar to Google DeepMind's Gemini Diffusion. The proof-of-concept implementation trains on WikiText for 30 minutes and produces surprisingly coherent text, validating that encoder-only models can be repurposed for generation by treating them as discrete diffusion models with multiple masking intensities. ## Full article daily.dev links to this article rather than hosting it.
