The 512GB Local LLM Guide
What a 512 GB Mac Studio actually does with large language models — measured, not estimated. $9, pre-order.
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. Cancel any time before delivery for a full refund, no questions.
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.
Pre-orders open shortly. Our checkout provider is still finishing account verification, and we will not take card details through anything improvised. Leave an address and you get the pre-order link the hour it works — at the $9 pre-order price, which does not go up for anyone on this list.
