How to Use Ori Harness With Any Model Through OpenRouter

If you're tired of wrestling with base URLs, API keys, and model mappings for every AI coding tool, Ori Harness now comes preconfigured to work with nearly any model through OpenRouter. Install the CLI once, log in with OpenRouter a single time, and you can run Codex, Claude Code, OpenCode, or Hermes with optimized configs out of the box—no undocumented env vars.

Tutorial

1. Install the Ori CLI.
2. Log in with OpenRouter once. This connects Ori to all the models available through OpenRouter.
3. Launch Codex, Claude Code, OpenCode, or Hermes. Ori automatically adjusts the harness for the model behind it, and for Claude Code that can cut the system prompt almost in half, lowering costs.

Wrapping Up

You now have one harness that handles the config for you. Log in once and start shipping.
