MiniMax Notes

Current default assumptions

  • MiniMax H3 is promising, but brute-force paths are too heavy to be the first bet on a 3070.
  • Speed-first and low-VRAM community workflows matter more than official purity for the first real test.

Strong current source workflows

  • models/minimax/minimax-h3-official-t2v/
  • models/minimax/minimax-h3-official-i2v/
  • models/minimax/minimax-h3-turbo-lora-community/
  • models/minimax/minimax-h3-int8-r2v-community/
  • models/minimax/minimax-h3-extender-ref2va/
  • models/minimax/minimax-h3-int8-r2v-javano2608-23/
  • models/minimax/minimax-h3-turbo-gguf-i2va/
  • models/minimax/minimax-h3-seamless-chain-v2/

Strong current heuristics

  • Prefer Turbo LoRA for the first text-to-video attempt.
  • Prefer INT8-based community workflows for reference-to-video exploration.
  • Keep attention and memory-efficiency helpers if they are already integrated and well documented.
  • Treat the same-day javawock7618 INT8 R2V import as the strongest current donor for local continuity and identity retention, but not as proof that the graph is light enough for a 3070.
  • Keep the GGUF I2VA path as an audio-aware fallback, not the default lane.

Current weak areas

  • No proof yet that MiniMax is truly practical on Chris's box.
  • Custom-node stack is more fragile than the current flux2klein path.
  • The full seamless-chain graph is interesting, but it is not a clean baseline for the first maintained master.

Best current optimization direction

  • Keep optimized/text-to-video/minimax-h3-3070-turbo-master/ as the first MiniMax default.
  • Keep the INT8 reference-video workflow as the next donor for future low-VRAM optimization.
  • Keep only two maintained optimized/image-to-video/ MiniMax lanes:
    • optimized/image-to-video/minimax-h3-best-current-r2v-master-480p-3x10s/ as the reference-first generation master
    • optimized/image-to-video/minimax-h3-contex-loop-3070-safe-60s-awq-int8/ as the imported-video extension master
  • Use the new same-day javawock7618 INT8 R2V import as the main donor for future best-current-r2v revisions if the current master needs another pass.

Ref2VA prompt guidance

  • For MiniMax H3 Ref2VA, treat 480p and 10s as the safe planning baseline on 8GB VRAM unless direct tests prove otherwise.
  • Chris's later manual testing suggests 20s @ 480p is a real context-loop candidate ceiling, so maintained loop masters should compare 3 x 20s against 6 x 10s rather than assuming only 10s clips are viable.
  • In the maintained best-current-r2v-master, keep Picture 1 as the master scene / environment reference and Picture 2 as the primary full-body identity reference.
  • Use one master-scene reference to control environment/composition, one primary full-body reference per subject to control overall appearance, and headshots only to reinforce facial identity.
  • Explicitly state when multiple images represent the same subject, and explicitly tell the model to ignore character-reference backgrounds so they do not fight the master environment.
  • Use the prompt mainly for action, performance, camera movement, dialogue, and audio rather than re-describing scene details already visible in the references.
  • Full guidance now lives in optimized/notes/minimax-h3-ref2va-prompt-guidelines.md.

Loop enhancement direction

  • For the target maintained Contex Loop quality workflow, treat the second-pass enhancement lane as mandatory, not optional.
  • That second pass should reuse the conditioning from the original MiniMaxH3ReferenceToVideo node that gathers the reference images, and feed that original reference conditioning back into the guider for the enhancement pass instead of relying only on first-pass latent continuity.
  • Current preferred sampler/scheduler direction for that enhancement pass is Euler plus beta.

What needs Monday proof

  • whether the Turbo LoRA workflow is just technically possible or actually usable
  • whether the source-recommended 8-step path holds up in quality
  • whether MiniMax feels like a real challenger to LTX locally
  • whether the same-day INT8 R2V donor stays practical on the 3070 once the helper stack is trimmed to the minimum
