Can Mac Studio M1 Ultra 128 GB run Llama 3.2 3B Instruct?

128 GB unified · 800 GB/s memory bandwidth · Llama 3.2 3B Instruct has 3.2B parameters.

Short answer

Yes, excellent for chat; not recommended for coding in a repository.

Best quantization for chat: 6-bit (2.5 GB of weights) on LM Studio. Generation: 120–160 tok/s, leaving about 114 GB free for your other apps.

How it rates for each workload

Same model and machine, different jobs. Agents and long documents send far bigger prompts than chat, so they need much more speed and memory.

Get it running

Copy-paste commands for the 8-bit build with a 64K context. Ollama and llama.cpp download the file straight from Hugging Face.

ollama run hf.co/unsloth/Llama-3.2-3B-Instruct-GGUF:Q8_0

Downloads 3.42 GB (Q8_0). Ollama's default context is small: set OLLAMA_CONTEXT_LENGTH=65536 before `ollama serve` for long prompts.
