TogetherLink is an open-source tool that lets you run your existing local coding tools against models hosted by Together AI. Instead of configuring each tool’s provider settings by hand, you launch it through TogetherLink and it wires everything up for you.

​
Prerequisites

  • A Together AI API key.
  • The coding tool you want to use, already installed on your machine. TogetherLink does not install the underlying tool for you.

​
Get started

Install TogetherLink with the one-line installer. The installer will also install Bun if it is not already present:
Launch the interactive selector to pick a tool:
If no Together AI API key is already configured or available through your environment, the interactive launcher automatically opens the API-key configuration flow so you can provide one. Or run a tool directly. tclaude, tcodex, tpi, and topencode are installed as standalone shortcuts: togetherlink chatgpt is only available as a togetherlink subcommand — there is no standalone shortcut.

​
Configure your API key

Run the built-in configuration command to store your Together AI API key:
togetherlink configure also optionally asks for an Exa API key, which enables web search inside Claude Code.
You can also skip configure by exporting TOGETHER_API_KEY in your shell environment. TogetherLink will pick it up automatically.

​
How it works

TogetherLink launches the selected coding tool configured to use compatible models hosted by Together AI. How that configuration is applied depends on the tool:
  • Claude Code and Codex route through a shared local translation proxy daemon managed by TogetherLink. Their normal configuration files remain unchanged.
  • OpenCode and Pi Code receive temporary per-run configuration; their normal configuration files remain unchanged. Pi Code may write temporary files during a run.
  • ChatGPT Desktop (alpha) is different: togetherlink chatgpt persistently modifies ChatGPT Desktop’s configuration so it points at Together AI, and those changes remain in place until you revert them.
To restore ChatGPT Desktop’s original configuration, run:
The installed TogetherLink CLI periodically checks for updates. When an update is installed, the next invocation uses the new version.
