<h2 id="minimax-h3-10eros-+-semantic-bridge-+-ultimate-upscale-(8gb-t2vi2v)">MiniMax H3 — 10Eros + Semantic Bridge + Ultimate Upscale (8GB T2V/I2V)</h2>A two-stage MiniMax H3 text-to-video graph for consumer 8GB cards.1. Stage 1 — 10Eros TURBO-hybrid generates a short AV clip at 0.3–0.4 MP in 6 steps (euler / simple). Turbo is already baked into 10Eros. Do not add LightX2V / ModelTC / other speed LoRAs.2. Semantic Bridge — an ~11 MB conditioning adapter (not a second video model). It blends a learned semantic residual into H3 text cond. Goal is tighter prompt structure, not extra VRAM. SenseNova is not needed at runtime.3. Stage 2 — MMH3 Ultimate Upscale with the official H3 3D latent upscaler, 8GB tiles, denoise 0.18.H3 is CFG-distilled. This graph uses BasicGuider — no negative prompt, no CFG. Put exclusions in the positive prompt.Example shot in the JSON: SFW golden-hour causeway, native stereo audio.<h2 id="more-graphs:-artrealmai.com-(https:artrealmai.com)">More graphs: <a target="_blank" rel="ugc" href="http://artrealmai.com">artrealmai.com</a> (<a target="_blank" rel="ugc" href="https://artrealmai.com">https://artrealmai.com</a>)</h2>Custom nodes (2 extra packs)Everything else is ComfyUI 0.33+ native MiniMax H3.1.
