Only just. Qwen2.5 14B fits on the Apple M4 (16GB) at Q3_K_M, which costs noticeable quality. Expect about 10 tokens/second. A card with more memory is a better experience.

Try other context lengths

Run it with Ollama

Ollama's default qwen2.5:14b download is Q4_K_M, which needs about 11.1 GB, more than the 10.7 GB available. Download the Q3_K_M GGUF instead (LM Studio lists quants per model), or try a smaller context length.
