Codex + HY3 is Insane (FREE!)

Use Codex for FREE with Tencent HY3 (OpenRouter API) + OmniRoot Backup

The video shows how to use Codex for free by plugging Tencent’s new open-source HY3 model into Codex via a free OpenRouter API (available for about two weeks, until around July 21). The creator demonstrates a custom setup with goal mode and a workspace where you can preview and manage past builds, plus a separate “HY3 Coder” that runs directly on HY3 without Codex. They explain the workflow: Codex acts as the hands (writes files, runs commands) while HY3 is the brain (agentic coding and tool calling), and you can swap the model in the config or have Claude/Claude Desktop set it up. If rate-limited, you can switch to OmniRoot, another free API, and also use HY3 inside Hermes as a free agent profile.
