Run Llama 405B locally.
$1,499 a month.
Not $18,000.
Rent a bare-metal Mac Studio M3 Ultra with 512 GB unified memory — the only consumer-class machine that holds Llama 3.1 405B, DeepSeek-V3, and Kimi-K2 1T MoE entirely in memory. SSH-ready in 90 seconds. Yours alone.
Same frontier models.
About 1/12 the monthly cost.
For memory-bound inference (MoE, long context, 70B+ dense), Apple Silicon wins on $/token and $/GB — and you get a dedicated machine, not a slot in someone's pool.
