Together Link - now in beta
Use open models in your harness
Pair your favorite coding agent with affordable open models. Together Link helps you track usage and keep costs down.
Why use Together Link?
Your agents running on open models, with transparent pricing.
Keep the harness you already know
Claude Code, Claude Desktop, Codex in the ChatGPT app, OpenCode, and Pi. Your login, settings, history, and habits stay exactly where they are.
Cut agent spend by over 50%
Open models cost a fraction of closed frontier APIs per token. Moving your team's everyday coding work onto them cuts the bill by more than half.
Get frontier quality on models you control
GLM 5.3, Kimi K3, DeepSeek V4.1 Flash, and MiniMax M3 handle real coding work at frontier level. With open weights they're fully in your control.
Access leading open frontier models
Auto Router is the default. Or pick a model yourself, right from your agent’s model menu.

Pick from a collection of top open models and run them in the harness you use with one line of code.
Automatic routing
Per-session routingLower costFrontier when neededSet the model to Auto. The router weighs initial session tasks on their way through: quick work goes to GLM 5.3 and harder problems get Opus 5.5.

Your Claude Code login and subscription
~/.claude settings, memory, and history
Web search, via an optional Exa key
Claude Desktop
One command installs a reversible profile and reopens the app with the Together lineup in its model menu for Chat, Cowork, and Code alike.
What you keep

Together Link FAQ
Longer answers live in the docs, which your agent can read on its own.
What is Together Link?
Together Link is a free, open-source tool that connects your coding agent, like Claude Code or Codex, to open models on Together AI, including Kimi K3, GLM 5.3, MiniMax M3, and DeepSeek V4.1 Flash. You pay only for model usage at Together AI's per-token rates.
Which coding agents does Together Link work with?
Claude Code, Claude Desktop, Codex, ChatGPT Desktop, OpenCode (version 2+), and Pi (version 0.80.8+). Each launches with its own command, such as `togetherlink claude`.
What do I need to get started with Together Link?
A Together AI API key, macOS or Linux, and a supported coding agent. Install with `curl -fsSL https://link.together.ai/install | bash`, then run `togetherlink configure` to add your key.
How does Together Link's auto router choose a model?
The router reads the first task in each session and sends quick work to a low-cost model and hard problems to a more capable one. With an Anthropic API key in Claude Code or Claude Desktop, it routes between Opus 5.5 and GLM 5.3.
Does Together Link change my existing Claude Code or Codex settings?
No. Terminal agents get settings that last only for that session. Claude Desktop and ChatGPT Desktop use a separate profile, and `togetherlink claude-desktop off` or `togetherlink chatgpt off` switches back.
How much can I save with Together Link, and how do I track spending?
Together Link cuts coding agent spend by 50-80% compared with running every session on Opus 5.5. Each session prints a cost receipt when you exit, and `togetherlink usage` shows your running total.
