阿里云Публичная демонстрация показывает, что MiniMax-H3 может генерировать видео локально на одной RTX 5090. Однако требования зависят от точности, разрешения и выбранного рабочего процесса, а полный конвейер 2K не работает полностью офлайн.
MiniMax представила демонстрацию, в которой H3 генерирует видео локально на одной RTX 5090. Согласно описанию, модель принимает текстовые, графические, видео- и аудиоссылки и способна создавать короткие ролики с синхронизированным стереозвуком. Веса модели опубликованы, а сообщество разрабатывает интеграции с инструментами вроде ComfyUI.
При этом демонстрацию на одной видеокарте не следует считать доказательством того, что любая конфигурация H3 удобно и полностью работает офлайн на одной RTX 5090. Технические материалы указывают, что исходный вариант задачи содержит около 134 ГиБ весов, а высококачественные или lossless-конфигурации могут требовать нескольких серверных GPU. На потребительских видеокартах обычно применяются квантизация, выгрузка в оперативную память или на диск и сниженные настройки, влияющие на скорость, точность или разрешение.
Кроме того, полный рабочий процесс в 2K, по имеющимся данным, использует компоненты, доступные только через API, включая Context-IR и Regenerate-2K. Поэтому корректнее говорить, что отдельные сценарии генерации H3 уже доступны на потребительском оборудовании, а не что весь стек максимального качества работает локально на одной RTX 5090.
Проверка источников не гарантирует вечную точность. Учитывайте первоисточник, время наблюдения и последующие исправления.
### Can MiniMax H3 run completely locally? H3-Base can run locally and generates 768p-class video with stereo audio. The official full-2K workflow cannot run completely locally because Context-IR and Regenerate-2K are API-only at launch. ### How much VRAM does MiniMax H3 need? There is no single number. One original task partition contains about 134 GiB of weights. Published lossless recipes include four 80 GB H100s, four H200s and two 32 GB RTX 5090s with roughly 384 GiB host RAM. Diffusers documents INT8 streaming on 24–32 GB cards with about 75 GB host RAM, and reduced-canvas operation on 12–16 GB cards with more offload. Those smaller routes trade speed, precision or both. ### Will MiniMax H3 run on a Mac? [...] Fast interconnect matters. Ulysses sequence parallelism divides the long token sequence but does not automatically shard every weight. Tensor parallelism and FSDP reduce per-card weight residency at the cost of collectives. High-bandwidth single-node NVLink/NVSwitch or
Able-Instruction1009 •11h ago 3060 12GB / 32GB RAM / Ubuntu. Not a CUDA OOM: the whole machine locked, SSH included, reset button both times. Culprit was in the startup log — Enabled pinned memory 30419.0. ComfyUI page-locking ~30GB on a 32GB system. The kernel can’t reclaim pinned memory, so you get swap livelock instead of an OOM kill. Add --disable-pinned-memory (I also run --cache-none --fast-disk --disable-smart-memory --lowvram). Now: 480p, 5s @ 24fps, native audio, one ref image. Peak 7.4GB RAM used and 6.2GB VRAM — nowhere near the ceiling I thought I was hitting. More replies Image 13: u/Full_Astronomer_5438 avatar Full_Astronomer_5438 •16h ago will look into that, thanks!

Holy, those insanae releases: MiniMax released a 33B video model that generates synchronized stereo audio and runs on one RTX 5090. H3 combines text, images, video and audio references for generation and editing, with clips up to 15 seconds. ComfyUI’s optimized stack is roughly 40GB, using dynamic RAM/SSD offloading to fit consumer GPUs. Early 5090 (!) tests produced five seconds at native 768p-class resolution in around 5.5 minutes. MiniMax calls it open source, but several core pieces remain server-side: context orchestration, 2K regeneration and sparse attention. Open weights. Closed quality stack. Restricted geography. However, H3 is a major step for local video, but also a reminder that “downloadable” does not mean open source in general. Btw: It also cannot legally be used under
