Researcher trains 210M text-to-image DiT from scratch on single GPU

By PulseAugur Editorial · [2 sources] ·

An individual trained a 210 million parameter text-to-image diffusion transformer from scratch, completing the process in 3.5 days on a single GPU. Key findings from this experiment include the observation that learned null attention slots become the primary sink for cross-attention mass, and that the flow-matching loss serves as a health signal rather than a direct quality indicator. The training-time timestep shift was found to be more impactful than simply doubling the number of training steps. AI

IMPACT Provides insights into efficient training of diffusion models and attention mechanisms, potentially informing future model development.
