I Realized at 35,000 Feet That I Can't Code Without an LLM Anymore

April 30, 2026 (3mo ago)

35,000 feet. No wifi. No Claude. Three hours of open laptop, forgetting function signatures, writing unit tests manually. I'd offloaded something I didn't mean to offload.

I landed and set up a local model before the next flight. Four commands to run an LLM on macOS:

  • brew install ollama

  • brew services start ollama

  • ollama pull qwen2.5-coder:14b

  • ollama run qwen2.5-coder:14b --verbose "write a python function to reverse a linked list"

That's it.

Qwen 2.5-Coder 14B, ~9GB on disk, ~12GB RAM loaded, ~20 tok/s on my M3 Pro 18GB. Tokens streaming locally. No API key, no rate limit, no auth round-trip.

Chrome closed. Slack closed. Everything fighting for RAM, closed. 14B on 18GB is the ceiling, not the aspirational pick.

I know Qwen2.5 is old, Qwen3.6-27B dropped about a week ago. It matches Claude Opus on Terminal-Bench 2.0, outscores models 15x its size on SWE-bench. It wants 24GB unified memory. My laptop has 18 :(

Bridging this into Claude Code is next on my list. claude-code-router translates between Anthropic's Messages API and the OpenAI format Ollama speaks. One env var points Claude Code at localhost.

That's the difference between "I have a local model" and "I can keep shipping on the plane."

18GB is laggy, not livable for serious agentic loops, I believe 32GB is the new floor for local coding that doesn't fight you.

Has anyone tried MLX for Apple M series? Curious how it compares to Ollama on throughput, and whether anyone's bridged it into Claude Code.

Online, the frontier model wins. Offline, the model on my laptop wins.
