Figures from each repo's GitHub metadata at analysis time.
Reproducing the benchmark requires multiple RTX 3090 GPUs and a matching vLLM setup, the repo itself is mainly data, not a runnable app.
This repository shares the raw results and data files from a single overnight test comparing two ways of running a large AI language model on home computer hardware. The author ran everything on their own machine, using four consumer graphics cards, to see whether a speed up technique called speculative decoding actually makes a large model respond faster in practice, not just in official marketing claims. Speculative decoding works by having a smaller, faster draft model guess several words ahead, which a larger main model then checks and accepts or rejects. If the guesses are usually right, this can speed things up a lot. The author tested this setup, called DFlash, against running the large model on its own, across 152 separate measurement runs, using both random test text and real coding related prompts. The headline finding is that the content of the prompt matters enormously. On randomly generated text, the draft model's guesses were accepted only around one fifth of the time, giving little to no speed benefit. But on real coding prompts, the acceptance rate nearly doubled, and the combined system ran about fifty percent faster than the large model running alone. On a different set of technical prompts, the speed up mostly disappeared. The author also found that under heavy concurrent load, checking the draft model's guesses became expensive enough to slow the whole system down compared to just running the large model by itself. The repository includes the exact commands and environment details used to reproduce the test, raw spreadsheet style result files, machine readable comparison summaries, chart images, and detailed per test logs including graphics card temperature and power readings. The author is upfront that this was a single run with no repeated trials for statistical confidence, and notes that official published speed up numbers for this technique were measured under different hardware and workload conditions than the ones used here.
A shared set of raw benchmark data testing whether a speed up technique called speculative decoding actually makes a large AI model faster on consumer graphics cards, run on real hardware overnight.
Mainly Python. The stack also includes Python, vLLM, CUDA.
The README does not state a license, so usage terms are unclear.
Setup difficulty is rated hard, with roughly 1day+ to a first successful run.
Mainly researcher.
