Tencent officially launched the 1.0-Lite version after open-sourcing Hunyuan 3D World Model 1.0. This model is the world's first open-source 3D world generation model to support CG pipelines, and now the Lite version further lowers the hardware barrier, allowing consumer-grade GPU users to run complex AI 3D modeling and virtual world generation tasks.
1. The technical optimization of Hunyuan 3D World Model 1.0-Lite
- Dynamic FP8 Quantization memory
- requirements have been reduced from 26GB to less than 17GB, a reduction of about 35% Consumer GPUs such as the RTX 4080 and 4090 also run smoothly.
- SageAttention Quantization Optimization
- quantizes the Q, K, and V matrices of transformers to INT8, combining dynamic smoothing with hardware acceleration to increase AI inference speed by more than 3 times while reducing accuracy loss of less than 1%, ensuring the quality of 3D world generation.
- Cache Algorithm Acceleration streamlines
- the AI-driven 3D modeling process by optimizing redundant time steps, greatly increasing inference efficiency, and improving the real-time generation experience.
2. The Significance of Consumer-grade GPUs
- is popularizing: Previously, high-end graphics cards were required to run full 3D world generation models, but now mainstream GPU users such as the RTX 40 series can participate.
- Developer-Friendly: Small to medium-sized teams and independent developers can enter the AI 3D content creation space at a low cost.
- Ecosystem Expansion: Support for consumer-grade GPUs will facilitate the rapid growth of the open-source AI 3D modeling community.
