+# MiniMax H3 INT8 First-Last-Frame
+
+## Summary
+
+`MiniMax H3` first-last-frame workflow from the same-day `javawock7618` pack. This is the controlled transition path for image-guided video.
+
+## Model Family
+
+- `minimax`
+
+## Status
+
+- `imported-only`
+
+## Source
+
+- Workflow pack page: <https://huggingface.co/javawock7618/comfy-MiniMax-H3-workflows>
+- Workflow file: <https://huggingface.co/javawock7618/comfy-MiniMax-H3-workflows/resolve/main/MiniMax_int8_I2V-javano2608.6.json>
+- Original publisher: `javawock7618`
+- Date imported: `2026-08-09`
+
+## Developer notes
+
+- The source README describes this as the `First-Last-Frame` workflow.
+- It uses INT8, Sol-Attn, Spectrum acceleration, Motion Context, Lightx2v LoRA, Turbo LoRA support, and latent upscaling.
+- The pack says the FLF workflow is the one that uses Motion Context.
+
+## Our notes
+
+- Strongest new MiniMax import for controlled transitions and scene morphing.
+- On a `3070`, this looks tight to heavy, but the INT8 path is the only reason it feels worth trying locally.
+- Good candidate to compare directly against LTX first-frame or multi-reference workflows.
+
+## Required custom nodes
+
+- `ComfyUI-SolAttn_triton`
+- `ComfyUI-Spectrum-MiniMax-H3`
+- `ComfyUI-H3-Motion-Context`
+- `ComfyUI-MiniMaxH3_LatentUpscaler`
+
+## Required models
+
+- `Comfy-Org/MiniMax-H3`
+- `Kijai/MiniMax-H3_comfy`
+- `drbaph/MiniMax-H3-Turbo-Lora-ComfyUI` if the turbo path is enabled
+
+## Notes
+
+- Best same-day MiniMax workflow for first/last-frame control.
