What AI models can an Apple M1 Max 32GB run?

32 GB puts the 70B class within comfortable reach and leaves room for the context window that makes those models worth running. Memory is shared with the CPU, so the practical ceiling is lower than the sticker number: macOS hands roughly three quarters of it to the GPU by default.

The short answer

Assuming an 8k context window and default settings, these are the models worth downloading first.

Model

Simulated from our estimate at a 512-token question, not a recording. Assumes nothing else is competing for the GPU.

Where it sits

The GPU can use about 22.4 GB of this machine's 32 GB by default, so for planning it behaves like a 16 GB card with different bandwidth. The 16 GB guide explains what that tier runs and where it runs out, and the bandwidth guide explains why 400 GB/s decides how fast it answers.

Our indicative price for this machine is $1,400 new, reviewed 2026-09-01. That is 2.3 GB of memory and 29 GB/s of bandwidth for every $100. Prices move, so treat these as a place to start a search and not a quote.

What it will not run

35 of the 86 architectures we track are out of reach here, even at 2-bit precision.

If you want more headroom

The next steps up in memory, in order. More memory changes which models load at all; more bandwidth changes how fast they answer, so the two are worth weighing separately.

Questions people ask about an Apple M1 Max 32GB

How much VRAM does an Apple M1 Max 32GB have?

The Apple M1 Max 32GB has 32 GB of unified memory shared with the CPU, of which roughly 22.4 GB is available to a model once the operating system takes its share.

Can an Apple M1 Max 32GB run a 70B model?

Yes, once the macOS GPU memory limit is raised. At IQ3_XXS it needs 28.95 GB and runs at around 113.4 tokens per second.

What is the best local model for an Apple M1 Max 32GB?

Gemma 4 12B Instruct at Q8_0 is the strongest all-round fit: 13.52 GB used, around 20.7 tokens per second at 8k context.
