Luce-Org/lucebox-hub

LuceBox is an Apache-2.0 speculative-decoding inference server in C++ that targets consumer hardware, with a single-binary deployment model and a small memory footprint compared to mainstream servers like vLLM or SGLang. It is one of the first open-source servers built specifically around speculative decoding on consumer GPUs.

Why it matters

Useful for builders who want to squeeze usable tokens-per-second out of consumer GPUs without renting a datacenter: deploy LuceBox on a single 4090 or 5090, point an OpenAI-compatible client at it, and benchmark your prompt mix against a vLLM reference to see whether the speculative path actually wins on your workload.

Who should use it

local-AI builders running on a single 4090/5090teams that want higher tokens/sec without paying for a datacenter GPUresearchers studying speculative decoding in production

Who should skip it

Skip if the source link, docs, or setup requirements do not match your workflow.

Risk explanation

speculative decoding gains are workload-dependent; validate on your own prompt mix, not just the project's published numbers.
