Cline

Cline is an AI-powered coding assistant designed for interactive, agent-style development workflows. It enables developers to reason over codebases, plan multi-step changes, and execute actions using large language models (LLMs), all from within the editor.

Cline supports OpenRouter as an API provider, allowing you to access a wide range of language models, including Arcee AI’s Trinity models, through a single OpenAI-compatible endpoint. This simplifies setup, enables easy experimentation across models, and centralizes authentication, usage tracking, and billing.

This guide walks through how to configure Cline to use Trinity models via OpenRouter.
