Key Points

  • The author shares a local AI low-end build with hardware such as R5 5600X, 32GB RAM, and an RTX 3070, plus a software stack including llama.cpp (CUDA), OmniCoder-9B, Qwen Code CLI, and Superpowers for coding tasks.
  • They mention testing alternatives like Opencode + GLM-5 and Antigravity with Gemini 3.1 High to compare options.
  • The setup reportedly offers a good balance between speed and output quality, handles longer responses, and is stable enough for regular coding use.
  • Because it runs fully locally, there are no limits or ongoing costs, making it practical for daily use.

Hello everyone,

After a long time testing different local models, quantizations, and tools, I wanted to share the setup I ended up sticking with for coding.

Hardware:
R5 5600X / 32GB RAM / RTX 3070 8GB

Setup:

  • llama.cpp (CUDA)
  • OmniCoder-9B (Q4_K_M, Q8 cache, 64K context)
  • Qwen Code CLI
  • Superpowers (GitHub)

I also tested Opencode + GLM-5 and Antigravity with Gemini 3.1 High.

From my experience, this setup gives a good balance between speed and output quality. It handles longer responses well and feels stable enough for regular coding use, especially for entry to intermediate tasks.

Since it’s fully local, there are no limits or costs, which makes it practical for daily use.

Curious to know what others are using and if there are better combinations I should try.
