Kitty Bridge: model tool for Hermes Agent

Local bridge that lets coding agents use any LLM provider, such as Claude Code with MiniMax

What Kitty Bridge does

Kitty Bridge is a local, deterministic bridge that sits between a coding agent and an LLM provider and translates each agent's native protocol in real time. It lets you run Claude Code with MiniMax, Codex with GLM or Gemini CLI with OpenRouter by choosing a provider and model with one setup command, and its repository description says it also works with OpenClaw and Hermes.

Profiles can use an API key or an existing ChatGPT Plus or Pro subscription authenticated through the browser. Balanced profiles mix a stronger and a cheaper model in one session by randomly distributing requests across them. Kitty runs on your machine, only forwards traffic to the provider you configure, has no filesystem or shell access, and uses no AI internally. It is tested on Linux, Windows and macOS.

Key features

Protocol translation between coding agents and LLM providers
One interactive command, kitty setup, to create a profile
Use of an existing ChatGPT Plus or Pro subscription through browser login
Balanced profiles that mix two models in one session
Runs locally with no filesystem or shell access of its own
Supports Claude Code, Codex, Gemini CLI and Kilo Code

When to use it

Running Claude Code against a cheaper coding-plan model
Switching an agent to a different provider when subscription limits run out
Mixing a frontier model and a smaller model in a single session

Who it is for: Developers who want to choose their own LLM provider for coding agents and keep costs down.

How it fits with Hermes Agent

The repository description lists Hermes among the agents it works with; the detailed flows in the README cover Claude Code, Codex, Gemini CLI and Kilo Code.

FAQ

What is Kitty Bridge?

Kitty Bridge is a local bridge between AI coding agents and LLM providers. It translates each agent's protocol so you can pair, for example, Claude Code with MiniMax or Codex with GLM.

Does Kitty Bridge work with Hermes Agent?

The repository description says it works with Hermes and OpenClaw as well as coding agents. The main documented examples use Claude Code, Codex, Gemini CLI and Kilo Code.

How do I install Kitty Bridge?

Run pip install kitty-bridge, then kitty setup. The wizard asks for a provider, a model and an API key or subscription login. It requires Python 3.10 or newer.
