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**.

✦ Why Arbiter?

Without Arbiter	With Arbiter
Claude Code only works with Anthropic's paid API	Routes through NVIDIA's free cloud models
You pay per token — costs stack up fast	Completely free with an NVIDIA API key
Limited to models Anthropic offers	Access models like Kimi K2, Mistral Large 3, Llama 3.3
Large models require enterprise hardware locally	Runs in the cloud — nothing to install beyond Python

**NVIDIA NIM is free.** Get an API key at [build.nvidia.com](https://build.nvidia.com) — no credit card, no per-token charges.

✦ 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.
