Observations (1)
Masked diffusion language models LLaDA-1.5 and Dream-7B, which are not explicitly conditioned on a timestep, carry a denoising-progress (latent timestep) signal in their residual streams whose per-timestep mean vectors concentrate in a low-dimensional subspace (most variance in fewer than three principal components) tracing an ordered, parabola-like curve
