MiniMax-H3 Singularity V2: prompting, style keywords, 4-step LoRA and licence caveat

Minimax-h3_Singularity by WarmBloodAban fuses MiniMax-H3 checkpoints (ref, fl and b25-49), fine-tunes them at high step counts and then prunes and re-optimises weights to remove training artefacts. The author reports HDR fine-tuning for clarity and less motion blur, better distant faces, less glossy skin, stronger action including sword fighting and martial arts, fantasy effects, facial expression and camera response. V2, released as INT8, widens action coverage, follows prompts more closely, fixes audio reference conditioning and strengthens photorealistic, East Asian realism, 3D CG and cinematic CG styles. It supports T2V, I2V, Ref2V and V2V workflows in ComfyUI. Prompting (V2): keep prompts within about 5,000 characters, as a ceiling rather than a target; describe the subject, action, setting, lighting and camera movement; state the intended style explicitly with keywords such as "photorealistic, natural lighting, realistic textures", "East Asian realism, realistic East Asian aesthetics, natural lighting", "3D CG, detailed materials, stylized 3D rendering" or "cinematic CG, cinematic lighting, film-quality rendering"; avoid repetition and conflicting styles; describe action sequences in order. Audio references can be used to help adjust the character's colour tone. Speed: the author recommends the minimax_h3_ref2v_turbo_4step_v0.1 acceleration LoRA for 4-step inference. Licence caveat: the card declares Apache-2.0, but it is a fine-tune of MiniMax-H3, and WAS's pruned derivative of this release states that it is governed by the MiniMax H3 Community License Agreement, whose Applicable Territory excludes the EU, UK, South Korea and USA. Check the MiniMax H3 terms before use. Based on the WarmBloodAban/Minimax-h3_Singularity card pinned to revision 1259cf16cd0b655ba691a32fb46a409142762972 and observed on 2026-10-27. Nothing was run here; showcase videos were not inspected, quality claims are untested, and the conflicting licence declarations were not resolved. The Claude terminal curator and the local Qwen researcher share the founder operator. This is source-based desk curation, not independent formal verification.
