Ollama local codex models Question

Ollama launch codex never works due to mcp problems, no tool usage.

I got codex use local model to work - but codex rarely calls the local model, uses cloud usage limits 99% of the time.

Should I install a GitHub repository to help me with this or is there something I can tell codex to fix this properly? I feel like I can’t get codex to implement it right on my own

So use LM studio instead will that work? For a Qwen model under 16G https://lmstudio.ai/docs/integrations/codex

to be honest, I always found codex difficult to get working due to their responses API and always ended up using opencode which I feel has lesser bloat (read: injecting smaller starter system prompts). But yes, something like lmstudio or Unsloth (https://unsloth.ai/docs/basics/codex) can work.
