<h1 id="lazy-minimax-h3-all-in-one-(auto-switching)">Lazy MiniMax H3 — All-in-One (Auto-Switching)</h1>Pick the workflow type. Everything else follows.This is a Lazy MiniMax H3 graph: one selector, one conditioner path, one sampler stack. Set T2V / I2V / FL2V / R2V and the all-in-one nodes route models, frames, refs, and audio for you — no muted branches, no duplicate samplers, no “which UNET did I leave on?”<hr /><h2 id="the-lazy-idea">The Lazy idea</h2>Lazy here means the workflow does the bookkeeping.<ul><li>You choose the workflow type once.</li><li>Lazy MiniMax All-in-One builds the right conditioning for that mode.</li><li>Lazy Model Switcher picks fl2va (text / image / first–last) or ref2va (reference).</li><li>Lazy Image Loaders only emit what that mode needs; unused roles hard-gate off so optional sockets stay empty.</li><li>LazyPrompt can expand a short idea into a MiniMax-ready prompt — then get out of the way.</li></ul>Everything is modular.

Lazy MiniMax H3 All-in-One

Fixed some oversights on wiring.Workflow now only uses Vsaan212 and KjNodesif you downloaded before, update vsaan212 nodes to get the new nodes. added lazy documentation nodes. use the drop down to select this workflows documentation.3 sample workflows for I2v, First last and reference to show how you can rearrange the nodes for different workflows.Added hugging face link to the "Clip For prompt enhance" node<a target="_blank" rel="ugc" href="https://github.com/vsaan212/Vsaan212-workflow-utilities/">https://github.com/vsaan212/Vsaan212-workflow-utilities/</a> documentation is more in depth.any suggestions? let me knowFeel free to use any of this in your nodes or workflows.
