Minimax H3 is a Local AI Video BEAST for Anyone & Everyone.
MiniMax H3 is an open-weight AI video model with native audio, and I ran it locally on my own GPU to see whether it actually holds up. I test original 5- and 15-second generations, compare H3 with FLUX.3 and Wan 3.0, and look at community setups ranging from low-VRAM PCs to Apple silicon. The quality is not frontier-perfect, but getting coherent HD video and audio without credits or a subscription is a pretty wild shift. I also cover setup options, performance tradeoffs, the Heretic encoder, and the real safety questions that come with capable open weights. ▼ Link(s) From Today’s Video: OFFICIAL MINIMAX H3 + COMFYUI MiniMax H3 official open-weight announcement: https://x.com/Hailuo_AI/status/2084123156818915727 MiniMax H3 official Hugging Face model: https://huggingface.co/MiniMaxAI/MiniMax-H3 MiniMax H3 official license: https://huggingface.co/MiniMaxAI/MiniMax-H3/blob/main/LICENSE Official ComfyUI MiniMax H3 page: https://comfy.org/minimax ComfyUI-optimized MiniMax H3 weights: https://huggingface.co/Comfy-Org/MiniMax-H3 Official ComfyUI repository: https://github.com/Comfy-Org/ComfyUI Official ComfyUI H3 text-to-video workflow: https://github.com/Comfy-Org/workflow_templates/blob/main/templates/video_minimax_h3_t2v.json Official ComfyUI H3 image-to-video workflow: https://github.com/Comfy-Org/workflow_templates/blob/main/templates/video_minimax_h3_i2v.json Official ComfyUI H3 reference-to-video workflow: https://github.com/Comfy-Org/workflow_templates/blob/main/templates/video_minimax_h3_r2v.json EASY INSTALLS + QUANTIZED VERSIONS MiniMax H3 NF4 files for DiffSynth Studio / Mac: https://modelscope.ai/models/DiffSynth-Studio/MiniMax-H3-NF4/files ModelScope: run MiniMax H3 locally on Mac with 8GB VRAM: https://x.com/ModelScope2022/status/2084625441940279770 Maestro + WanGP one-click H3 setup through Pinokio: https://x.com/cocktailpeanut/status/2084669538759561289 Official Pinokio download: https://pinokio.co/ Phosphene H3 support for Apple silicon: https://x.com/cocktailpeanut/status/2084363957293453611 COMMUNITY HARDWARE + SPEED TESTS MiniMax H3 on an RTX 4060 Ti 16GB: https://x.com/Spectromachina/status/2084307393081401499 480p H3 generation on a modest PC with Codex setup: https://x.com/aigeboku/status/2084241976988512576 SageAttention H3 speed test: https://x.com/luta_ai/status/2084601739148415134 MiniMax H3 Turbo LoRA speedup: https://x.com/aisearchio/status/2085246344990760991 H3 Google Colab cost comparison: https://x.com/yachimat_manga/status/2084615263492702667 HERETIC ENCODER + SAFETY DISCUSSION MiniMax H3 Heretic Qwen encoder files: https://huggingface.co/ethanfel/Qwen3-VL-32B-Ultra-Heretic-H3-ComfyUI-INT8-ConvRot Wildminder's H3 Heretic announcement: https://x.com/wildmindai/status/2084245950579523790 NVFP4 Heretic encoder conversion and VRAM notes: https://x.com/Tono_Ken3/status/2084534748534415607 Community report on the base model's content range: https://x.com/aisearchio/status/2084695995850645571 MODELS COMPARED IN THE VIDEO FLUX.3 official release announcement: https://x.com/bfl_ai/status/2084693191484469305 Wan 3.0 public beta announcement: https://x.com/MattVidPro/status/2085358816086896927 MattVidPro Discord: https://discord.gg/mattvidpro Follow Me on Twitter: https://twitter.com/MattVidPro Buy me a Coffee! https://buymeacoffee.com/mattvidpro ▼ Extra Links of Interest: General AI Playlist: https://www.youtube.com/playlist?list=PLrfI66qWYbW3acrBQ4qltDBsjxaoGSl3I Instagram: instagram.com/mattvidpro Tiktok: tiktok.com/@mattvidpro Gaming & Extras Channel: https://www.youtube.com/@MattVidProGaming Let's work together! - For brand & sponsorship inquiries: https://tally.so/r/3xdz4E - For all other business inquiries: mattvidpro@smoothmedia.co Thanks for watching MattVideoProductions!
