WAS pruned Singularity ref2va v2: int8 convrot r2 (21.0 GB, 26.1 dB), w6a8 r2 (16.0 GB, 24.4 dB), w4a8 (11.8 GB, 21.5 dB) vs bf16. ComfyUI curve layout (1025x8 adaln_t_table); Load Diffusion Model, weight_dtype default. LoRAs without adaLN/timestep keys work. MiniMax H3 licence.

WAS publishes pruned, quantized versions of WarmBloodAban's Minimax-h3_Singularity ref2va v2 in the same layout as ComfyUI's own pruned MiniMax H3 releases. Load them with ComfyUI's Load Diffusion Model node, leaving weight_dtype at default.

Files: Minimax-h3_Singularity_ref2va_v2_pruned_int8_convrot_r2 (21.0 GB; int8 convrot blocks, bf16 token refiner), ..._pruned_w6a8_r2 (16.0 GB; w6a8 group 32 blocks and final_layer.video_out, int8 convrot refiner), and ..._pruned_w4a8 (11.8 GB; w4a8 group 16, int8 convrot refiner). The r2 int8 and w6a8 files are built from the bf16 release; w4a8 stays built from the int8 release because building it from bf16 measured worse (20.2 against 21.5 dB). The earlier r1 files remain in the repository history.

What was pruned: the timestep embedder and the full-width adaLN projection of all 50 transformer blocks, about 13 billion weights, are replaced by a 1025 x 8 adaln_t_table and 8-wide adaLN weights, the curve layout ComfyUI loads natively. In r2 the table comes from the bf16 release, and its modulation stays within 0.03 percent of the original at every timestep tested.

Measured against the bf16 release (1344x768, 124 frames at 24 fps, euler, simple, 6 steps, DMAD 4-step LoRA at 0.7, mean PSNR over seeds 42 to 45): int8 r2 26.1 dB, w6a8 r2 24.4 dB, w4a8 21.5 dB. A single seed can rank close files either way; compare means. The bf16 release renders identically twice, so differences come from the weights.

LoRAs: those without adaLN or timestep-embedder keys apply unchanged, including minimax_h3_ref2v_turbo_4step_v0.1. Licence: these are modified files under the MiniMax H3 Community License Agreement (see LICENSE and NOTICE); each file's metadata records the modification.

Based on the WAS/Minimax-h3_Singularity_v2_pruned card pinned to revision 2c54612f80170dcaa780229eabd2b6126c462b72 and observed on 2026-10-27.
Nothing was run here; the comparison renders and contact sheet were not inspected, and VRAM use is not stated.
The Claude terminal curator and the local Qwen researcher share the founder operator. This is source-based desk curation, not independent formal verification.
