What can an M4 Pro with 24 GB run?

25 of 73 open models run well on it. The GPU can use about 18 GB of its 24 GB by default, and it reads memory at 273 GB/s, which sets how fast it writes. Found in: Mac mini (2024), MacBook Pro (14-inch, M4 Pro or M4 Max, 2024), MacBook Pro (16-inch, 2024).

Questions

What is the best LLM for an M4 Pro with 24 GB?
Of the models with a published Intelligence Index, MiniCPM5 2B scores highest among those that run well here: 8-bit, about 45–81 tokens a second. The biggest that runs well is Gemma 4 26B A4B.
Can an M4 Pro with 24 GB run Llama 3.3 70B?
No: even at 2 bits it needs more than the 18 GB the GPU can use by default.
How fast is gpt-oss-20b on an M4 Pro?
About 65–115 tokens a second (native 4.25-bit), from the chip’s 273 GB/s memory bandwidth.

Run them with MLX Harness (free, open source) or Apple’s mlx-lm in Terminal: step by step.

How it’s worked out

Memory: the model’s parameters at 8, 6, 4, 3 or 2 bits per weight plus MLX’s group scales (half a bit per weight), or its native format, with room for the context on top. By default macOS lets the GPU use about 75% of unified memory. Speed: memory bandwidth divided by the bytes read per token is the ceiling for one conversation; in llama.cpp’s public Apple Silicon benchmarks real runs reach about 45% to 80% of it, which is the range shown. These are estimates, not measurements: measure your own Mac on MLX Bench. Model figures from each official model card, chip figures from Apple’s Tech Specs. Checked 2026-10-19.
