Can Mac mini M2 24 GB run Gemma 4 12B?
24 GB unified · 100 GB/s memory bandwidth · Gemma 4 12B has 12B parameters.
Short answer
Yes, acceptable for chat; borderline for coding in a repository.
Best quantization for chat: 5-bit (7.8 GB of weights) on LM Studio. Generation: 8–11 tok/s, leaving about 7.3 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.
