MiniMax H3 INT8 R2V Javawo 2608.23

Summary

Same-day MiniMax H3 reference-to-video workflow from the javawock7618 pack. This is the newest R2V variant in that collection and the most directly useful current MiniMax consistency path.

Developer notes

• The pack positions this as an INT8 reference-to-video workflow with:
  • Sol-Attn
  • Spectrum
  • optional Lightx2v LoRA
  • optional Turbo-LoRA
  • native Extend
  • latent upscaling
• The source README says the R2V graph uses the reference LoRA:
  • minimax_h3_ref_lora_rank_256_bf16.safetensors

Our notes

• This is the strongest same-day MiniMax import for character retention and reference control.
• It still looks heavy for an RTX 3070, but it is a real low-VRAM-oriented path rather than a generic full-fat MiniMax demo.
• Good fit for testing whether MiniMax H3 is now practical enough for local reference-video work.

Required custom nodes

• ComfyUI-SolAttn_triton
• ComfyUI-Spectrum-MiniMax-H3
• ComfyUI-MiniMaxH3_LatentUpscaler
• ComfyUI-KJNodes
• ComfyUI-Easy-Use
• ComfyUI-VideoHelperSuite

Required models

• Comfy-Org/MiniMax-H3
• minimax_h3_ref_lora_rank_256_bf16.safetensors from Kijai/MiniMax-H3-experimental
• lightx2v/Minimax-h3-Turbo if you enable the acceleration path
• drbaph/MiniMax-H3-Turbo-Lora-ComfyUI if you enable the optional turbo LoRA

Notes

• Best same-day MiniMax workflow for reference retention and identity control.
• Still experimental, but the most practical current MiniMax video path in this repo.
