Latent diffusion self-reports 6-7% multimodal reasoning gains, unreplicated

The Uni-LaDiR method self-reports a 7.3% relative gain over the strongest evaluated baselines across 11 vision-language benchmarks, and 6.1% across 2 robot manipulation suites, with no teacher observations used at inference.

The common prior approach concatenates modality-specific tokens; this method instead maps teacher reasoning steps via a unified encoder into shared latent-space tokens, and a diffusion model predicts the next block of thought tokens.

Note that all numbers are first-party evaluations with author-selected baselines and no independent replication; the preprint was submitted September 17 and revised to v2 on September 23.
