This is the dynamic-time, physically separate-Q/K/V counterpart of the stock-compatible 10Eros_Max INT8 checkpoint. It retains the original FP32 time MLP and dynamic rank-16 AdaLN path instead of using an adaln_t_table.

A ComfyUI core patch is required. Stock ComfyUI cannot load this file.

The compatible patch and its base-model documentation are maintained in MiniMax-H3-DynTime-sQKV. Download ComfyUI-MiniMax-H3-DT-sQKV.patch from that repository. The patch is deliberately not duplicated here.

This is a community conversion, not an official MiniMax or ComfyOrg release.

All 50 MiniMax-H3 transformer blocks remain present. This layout preserves the runtime time-conditioning calculation and avoids fusing Q, K, and V. It does not add model capacity; it changes how the original computation is represented and loaded.

Checkpoint size is not full-workflow peak VRAM. Resolution, frame count, attention backend, the Qwen3-VL text encoder, VAEs, and offload settings also consume memory.

Fine-tune conversion

The supplied full-width BF16 checkpoint was compared tensor-by-tensor with the local original MiniMax-H3 FL2VA source:

all 535 expected tensors and all 50 blocks were present;
shapes and dtypes matched the full-width architecture;
no NaN or Inf values were found;
503 tensors were bit-identical to the original source;
the intentional fine-tune consisted of 32 modified fused-QKV tensors in blocks 0–31.

For this checkpoint, each modified fused-QKV tensor was quantized with the same tensorwise INT8 ConvRot/Hadamard recipe used by the matching base profile, then split on exact Q/K/V row boundaries. Q, K, and V use independent per-row FP32 scales and quantization configuration tensors. A control comparison confirmed that the split payload is bit-identical to independently quantizing the three projections with the current quantizer.

Every tensor outside the permitted Q/K/V weight, scale, and configuration ranges remains byte-identical to the corresponding base DT-sQKV checkpoint.

Validation status

The file passed an independent byte-range audit:

file size, safetensors header, key inventory, shapes, and dtypes match the corresponding DT-sQKV reference checkpoint;
every byte outside Q/K/V ranges in blocks 0–31 remains identical to the reference;
all 288 replaced tensors match the separately generated 10Eros_Max payload;
modified weights differ from the base reference as expected.

Conversion and audit were CPU-only. No prompt-to-decoded-video perceptual A/B result is claimed yet. This validation proves container and conversion correctness, not subjective image or motion quality.

Installation

Back up or commit your ComfyUI core changes.
Download the linked core patch and verify it with git apply --check from the ComfyUI repository root before applying it.
Place the checkpoint in ComfyUI/models/diffusion_models/.
Restart ComfyUI and use the normal MiniMax-H3 FL2VA workflow.

The Qwen3-VL text encoder and the MiniMax-H3 video/audio VAEs are required but are not duplicated here.
