ktransformers: Run LLMs on 24GB VRAM

dosco · x · 2026-07-18

The **ktransformers** team from Tsinghua optimizes MoE model deployment with a straightforward approach: - Keeping frequently used experts on the GPU while offloading less common ones to the CPU, enabling larger models to run on smaller VRAM. - The post claims this allows **DeepSeek-V3 / R1 to support 139K context on 24GB VRAM**, achieving up to **28x** speedups over standard setups. It also makes fine-tuning DeepSeek-V3 on **4x RTX 4090** GPUs possible. - Developed by the **Tsinghua MADSYS Lab**, the project is licensed under **Apache 2.0** and has surpassed **17,000** stars on GitHub.
