Can a local AI model actually write a novel—and can it do it on hardware normal people already own? I’m benchmarking AI book generation across older GPUs, measuring speed, repetition, memory use, editing burden, and the surprisingly tiny cost of generating a 90,000-...
Local AI Benchmarks
Reproducible benchmarks of open-weights language models running on consumer hardware. Generation speed, repetition rates, memory footprints, and cost-per-book measured across three machines spanning six years of GPU generations — with the scripts, raw outputs, and failed runs published in full.
Can AI really generate a publishable novel in a day? I used BookyAI, a locally hosted Llama model, AutoCrit, and Amazon KDP to create and publish a 126,743-word novel with almost no human rewriting. Here is what worked, what broke, what AI invented, and what I learned a...
