ByteDance Open-Sources DreamLite for Offline Mobile Image Generation and Editing

告别云端依赖！字节开源新作DreamLite让手机秒变 AI 画板

ByteDance open-sourced DreamLite, a 0.39B-parameter unified diffusion model that generates or edits a 1024×1024 image on an iPhone 17 Pro in about 3 seconds, using 4-step DMD2 distillation and on-device offline inference without cloud dependency.

Why it matters: HKR-H/K/R all pass: 3-second on-device 1024×1024 generation is a strong hook, with 0.39B params and 4-step DMD2 as concrete claims. As a ByteDance open-source vision model, it sits below a general foundation-model release.
