Lucebox: LLM Speculative Inference Server
What it is
Lucebox is a C++17 inference engine optimized for heterogeneous hardware and consumer GPUs, utilizing custom kernels and speculative decoding techniques like DFlash and KVFlash. It accelerates LLM inference by combining draft models with target models to achieve significant speedups in prefill and decoding phases.
The problem it solves
Standard inference engines often fail to fully utilize consumer GPU capabilities or lack optimized speculative decoding paths for heterogeneous and non-datacenter hardware.
What you could use it for
- Accelerating LLM inference on consumer-grade NVIDIA GPUs (e.g., RTX 3090)
- Optimizing inference for AMD APUs and heterogeneous CPU/GPU setups
- Deploying large language models like Qwen, Gemma, and DeepSeek on local hardware
