concise 2-4 sentences. Then Read original. Use only provided info. The description is truncated: "Second, altho". Probably incomplete, but we must not invent. We need to summarize based on given content. We have title, authors, date, source, URL. The description says they propose a state-of-the-art masked discrete diffusion model for high-res text-to-image synthesis, addressing two challenges: continuous diffusion models refine entire image; standard MDMs lack self-correcting capability because discrete tokens cannot be modified once unmasked. That's what we have. So summary: "Nemotron-Labs-Diffusion-Image introduces a masked discrete diffusion model that improves high‑resolution text‑to‑image synthesis by enabling self‑correction of discrete tokens, overcoming limitations of continuous diffusion and prior masked image generation approaches." That's one sentence. Need 2-4 sentences. Maybe add that it addresses two key challenges: continuous diffusion refinement and lack of self‑correction in discrete tokens. Let's craft 2 sentences. Sentence 1: "Nemotron-Labs-Diffusion-Image presents a state‑of‑the‑art masked discrete diffusion model for high‑resolution text‑to‑image synthesis." Sentence 2: "It resolves two main issues — continuous diffusion’s global refinement and
