Claude Code  ──▶  Arbiter (localhost:4005)  ──▶  NVIDIA NIM Cloud  ──▶  Free Models

Claude Code only works with Anthropic's paid API by default. Arbiter breaks that lock — it sits between Claude Code and NVIDIA's free cloud API, transparently routing every request to models like **Kimi K2 0905**, **Mistral Large 3**, and **Llama 3.3 70B** at **zero cost**.

✦ Features

🧭 Task-aware model routing

Arbiter reads your last two messages and classifies the task before dispatching. Heavy work goes to the most capable model; quick questions go to the fastest one — automatically.
