-base : ollama run qwen2.5-coder:7b-base — it’s still the reference for this specific use case. ⚠️ Qwen 3.8: its reasoning is set very high by default and it “overthinks” simple requests — lower it to low (or turn it off) on first launch. ⚠️ License trap: Codestral 22B = Mistral Non-Production License → prohibited for coding at work. Qwen 3.5/3.8, Gemma 4, and Devstral are Apache 2.0. 💡 Running out of memory? Keep ~1.5 GB of VRAM free for context, or drop down one quantization level.🔌 To connect it to VS Code: Cline (multi-file agent), Aider (CLI) or Tabby/Twinny (FIM autocomplete) — they all connect to Ollama locally. The kit Local Copilot — ready-to-paste configs + tested setup — is available: /copilote-local.
Filter: 1–15B whose Q4_K_M fits under 14 GB. Bonus: 7–14B (peak iMac M4) and permissive licenses.
Criteria considered:
The scoring is fully transparent: see our methodology for details on VRAM/tokens/sec calculations.
iMac M4 16 GB: which model for local AI?
Mistral 7B Q4 (~4,5 GB) or Qwen 3 8B Q4 (~5 GB) — 25-32 tok/s, smooth for chat. See the iMac M4 guide.
iMac M4 vs. Mac mini M4 for LLMs?
Exactly the same M4 chip + same 120 GB/s bandwidth. iMac M4 = display + integrated design, more expensive. Mac mini M4 = compact server. See Mac mini M4.
iMac M4 24 / 32 GB: can you go up to 12-14B?
Yes — Mistral Nemo 12B Q4 (~7 GB) or Qwen 3 14B Q4 (~8 GB) run at 18–22 tok/s. Beyond that (30B), you need a Mac Studio. See Mac Studio.
Is the iMac M4 good for creative work + LLMs?
Yes—the 24" 4.5K display and the M4 handle Photoshop / Lightroom / Logic AND a Ollama running in the background without issues. Ideal solo creative workstation with a local LLM assistant.
