What minimax-h3-spatial-physics-lora is

空间物理 LoRA · Spatial & Physics LoRA (MiniMax-H3) 空间思维与物理逻辑 LoRA，基于 MiniMax-H3（Comfy-Org/MiniMax-H3）训练，让模型学会纯物体的空间关系与物理运动（碰撞、堆叠、掉落、遮挡等）。 本 LoRA 专注物体物理。 目前还是训练和测试阶段，一些素材片段以及打标问题导致LORA还不是特别稳定。下一阶段准备修复后重新训练。目前LORA也是可以使用，强度建议0.3 ~ 0.5。纯属是在原模型基础上稍微增强一点物理反馈。 最新是重新训练到了wushuspatialphysicsclean3000pruned.safetensors 版本。 视频对比 实测用了这个LORA，视频整体提升真实感物理的逻辑，比如物体碰撞的真实反馈。也可以用于一些打斗场景，人物真实碰撞的效果。 用了空间物理LORA的武打片段（强度 0.3） 没有用空间物理LORA的武打片段（同样提示词） 其他测试视频 （wushuspatialphysicsv23000.safetensors） 使用方法（ComfyUI） 1. 下载 .safetensors，放入 ComfyUI models/loras/ 2. LoraLoader 加载，strength 建议 0.8~1.0 3. 用空间/物理语言 prompt 描述物体运动 关键词库（从训练数据提炼） ① 主体/场景 - several colored objects 多个彩色物体（CLEVRER 风格） - rigid objects 刚体 / elastic objects 弹性物体 - metal objects 金属物体 - a ball / balls 球 - billiard balls 台球 - objects 通用物体 - on a table 桌面上（PhyCo 台球场景） - in a synthetic scene 合成场景（CLEVRER 风格） ② 物理行为 - collision / colliding 碰撞 - a single collision between objects 单次碰撞 - bouncing / rebound 弹跳/回弹 - with visible impact and bounce 可见撞击与反弹 - with minimal bounce 小幅度回弹 - rolling into a wall 滚向墙 - scattering 散射 / 四散 - momentum transfer 动量传递 - in motion 运动中的 ③ 空间一致性短语（关键！） - clear spatial layout 清晰的空间布局 - visible depth 可见的纵深 - consistent trajectories 一致的轨迹 - gravity-consistent / gravity-consistent movement 重力一致的运动 - gravity-consistent rebound trajectories 重力一致的回弹轨迹 - objects maintaining spatial relationships 物体保持空间关系 - realistic restitution 真实的恢复系数（回弹性） - rigid collision with momentum transfer 带动量传递的刚性碰撞 负面提示词建议 训练时 neg 为空（模型未学负向），建议只加画质/物理负向，不要加与物理矛盾的内容： 提示词示例（可直接使用） 碰撞类 1. several colored objects, a single collision between objects, metal objects with rigid, elastic collisions, clear spatial layout, visible depth, objects maintaining spatial relationships in a synthetic scene 2. several colored objects, objects colliding with visible impact and bounce, clear spatial layout, gravity-consistent trajectories 3. objects colliding with visible impact and bounce, clear spatial layout, gravity-consistent trajectories 弹跳/回弹类 4. Elastic objects bouncing with realistic restitution, clear spatial layout, gravity-consistent rebound trajectories 5. objects bouncing with realistic restitution, clear spatial layout, gravity-consistent rebound

Sizes & precisions

Open weights ship in several sizes and precisions. One page, all the variants — pick the one that fits your GPU. VRAM figures are estimates from model size.

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys minimax-h3-spatial-physics-lora for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (minimax-h3-spatial-physics-lora below is illustrative; you get the exact model name on deployment.)

$ curl -sS https://api.axforge.ai/v1/videos/generations \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"minimax-h3-spatial-physics-lora","prompt":"a drone shot over a forest"}'
