此前，腾讯混元3D世界模型的FP32版本虽能完整保留所有细节，但显存占用极高——其参数可能超过十亿个，通常需要配备大容量VRAM的GPU来提升推 理速度，因此消费级显卡根本无法支持。 8月15日，腾讯混元团队推出了3D世界模型的Lite版本。相较于以往26GB的显存需求，此次通过引入动态FP8（8位浮点格式）量化技术，将显存需求直接降 至17GB以下，消费级显卡也能流畅运行。 简单来说，FP32、FP16、FP8代表不同的「精度等级」。过去采用高精度的FP32技术时，虽能实现极高的精度还原，却会占用大量显存，还可能保留不必要 的细节（例如背景的天空贴图等其实并不需要如此精雕细琢）。 而此次动态FP8量化技术的核心，在于能实时监测模型运行时的数据分布，并针对不同模块进行动态适配：大部分关键区域采用FP16精度，像上述背景贴图 等非关键部分则动态调整为FP8精度。 这一技术大幅降低了显存占用，虽然在部分区域适当降低了精度，却让个人玩家也能轻松使用3D世界模型。 腾讯混元3D重塑3D建模流程 腾讯混元 3D 世界模型是行业内首个开源可编辑的世界生成模型，能根据用户提供的图片或文字信息，直接生成完整、可编辑且可交互的 ...
