Why Do Few-Step Text Latents Fail When Image Latents Work? Non-Commitment at Sharp Categorical Readouts
arXiv:2606.30705v1 Announce Type: new Abstract: Deterministic few-step generation succeeds on continuous image latents but collapses to incoherent text on continuous text latents, and we show the cause is geometric rather than a training or scaling deficiency: a smooth, regularity-limited deterministic map cannot resolve a discrete branch choice before a sharp categorical readout, so few-step failure is governed by decoder sharpness, not transport accuracy. In the overlapping regime of real text autoencoders, we prove (Theorem 3) that the posterior-mean terminal step flips tokens at the rate o
This research provides a fundamental understanding of a current limitation in AI model design, specifically contrasting the behavior of continuous latents in image versus text generation.
A strategic reader should care because this technical insight directly impacts the development and future capabilities of text-based generative AI, outlining a core challenge that needs to be addressed for more robust models.
The understanding of why few-step text generation fails due to 'non-commitment at sharp categorical readouts' reframes the approach to designing efficient and reliable text autoencoders.
