Introducing Ori Harness: the easiest way to use your favorite harness with OpenRouter.
Ori configures Codex, Claude Code, OpenCode, and Hermes out of the box to work with OpenRouter, with settings optimized per harness, for any model.
Claude Opus serves from 8 endpoints across Anthropic, Bedrock, Vertex, and Azure. If one has a bad 20 minutes, you can keep going, without any retry logic.
Where a harness behaves differently depending on the model behind it, ori adjusts the settings so you don't have to.
In Claude Code, one setting alone nearly halves the system prompt and meaningfully reduces task length and cost, and it isn't set by default when using a gateway.
agent harness — The scaffolding around a model that turns it into a working agent — the loop, the tools it can call, and the rules for when to stop.
system prompt — The standing instructions a model receives before any user input — defining its role, rules, tools, and tone for the whole conversation.
