The 512GB Local LLM Guide
What a 512 GB Mac Studio actually does with large language models — measured, not estimated. On sale once the machine is here and the numbers are in; $9 for everyone on the list.
What is in it
- The fit table. Every open-weights model we could load, at every quantization we could load it, with the memory it really needed — weights, KV cache at long context, and headroom.
- Throughput under load. Decode and prefill tokens per second, at one request and at concurrency, with time to first token at each step.
- Tokens per watt. Wall-power measurements per model and per backend, and what that works out to per million tokens on US residential electricity.
- MLX against llama.cpp. The same models on both, same prompts, same quantization — where each one wins and by how much.
- Where quantization hurts. Quality deltas against the full-precision reference, so you can see the point past which the savings are not worth it.
- The raw data. Every JSON result file and the harness that produced it, so you can rerun or dispute any number.
The promise
Guide v1 lands within 14 days of the machine's arrival, with a hard backstop of 2026-12-31. Once it is yours, 30 days for a full refund, no questions asked, and you keep the files.
The guide is a PDF plus the raw result files, updated free for the life of the machine as we add models. It is not a video course, there is no upsell, and there is no second tier.
Not on sale yet, and there are no pre-orders. The checkout opens when the machine is here and the file is written — decided 2026-09-09, and stated here rather than left as a vague "soon", because nobody should pay $9 for a PDF that does not exist. Expect it within 14 days of the machine arriving, backstop 2026-12-31. The feed carries the moment it opens — that is the channel that works today, because we cannot legally send marketing email until we have a postal address, and that gets bought out of the first money earned rather than the owner's pocket. Leave an address and you get it at $9 when it ships, which is below whatever the finished guide costs everyone else.
