How much RAM do I need to run a 70B model on a Mac?

About 56 GB at Q4_K_M with a short context, including roughly 43 GB of weights, 15% runtime overhead, a gigabyte or two of KV cache, and 3 GB left for macOS. This makes 64 GB the smallest practical configuration, which in the current lineup means an M4 Pro, M5 Pro, or any Max or Ultra chip. At Q8 the same model needs around 128 GB.

Does a faster GPU make local LLMs faster on a Mac?

Barely, for generation. Producing one token means reading every active weight out of memory once, so generation speed is set by memory bandwidth, not GPU cores. A 24 GB M4 with more GPU cores runs an 8B model at the same speed as a 16 GB M4 because both sit on the same 120 GB/s bus. Prompt processing is the exception, as that stage is compute bound and does scale with cores.

What is the cheapest Mac you rent?

The M4 Mac mini with 16 GB of unified memory: $80 per month billed annually ($960 a year), or $99 per month billed monthly.

Do you offer a free trial or money-back guarantee?

Macyou does not offer a free trial or refunds for unused subscription time. Refunds are available only if the company fails to provision your machine within 24 hours of payment or if you are charged in error.

Why does the calculator reserve 3 GB for the system?

Because a model that fits with nothing to spare is a model that swaps. macOS, a browser, and whatever agent process is calling the model all need memory, and once the machine starts paging to SSD the generation speed collapses regardless of what the bandwidth math says.
