Together Link: open models in the harness you already use. Start with one command today.

Together Link connects the harness your team already uses to the best open models on Together AI and cuts your spend by over 50%. Same agent, same workflow, a fraction of the bill.

Coding agents are now commonplace for engineering teams, and every task you give them, from a one-line fix to a full rewrite, often runs on the same premium model. At scale that gets expensive quickly: engineering orgs are spending anywhere from tens of thousands to millions of dollars a month on closed models.

Open models have meaningfully closed the gap between top models from closed labs. Leaders like Kimi K3 and GLM 5.3 now handle many of the hardest coding tasks at a fraction of the per-token price, while small and capable models like GLM 5.3 Flash and DeepSeek V4.1 Flash handle everyday coding tasks. Together Link brings them into the tools your team already knows.

Works where you already work

Together Link supports Claude Code, Claude Desktop, Codex (in the ChatGPT app and the CLI), OpenCode, and Pi. Your team keeps working normally: settings and logins stay as they were, there's nothing new to learn, and going back to the native closed models takes one command. You can be up and running on open models in just a few minutes.

Getting started

curl -fsSL https://link.together.ai/install | bash

1. Run one command to set up Together Link: Your agent opens exactly as before, now connected to Together AI with your Together AI API key. Create an account for an API key.
2. Use “Auto” to pick a model with the Together AI Router: It reads each session's first task and sends it to the right model: quick fixes go to fast, low-cost models, and hard problems get frontier capability. If you bring an Anthropic key, it routes between Opus 5.5 and GLM 5.3. Without one, it routes between GLM 5.3 and GLM 5.3 Flash. Routing happens once per session, so prompt caching keeps working.
3. See your savings after each session. A per-session tracker shows what you spent next to what the same session would have cost on Opus 5.5.

Billing runs on your existing Together API key, against serverless pay-as-you-go or credit packs. You don't need a separate contract.

Built on the serverless platform developers already choose

Together Link runs on Together's serverless inference, the same infrastructure developers already pick for these models on OpenRouter. Together AI serves the largest share of OpenRouter tokens for DeepSeek V4.1 Flash (40.8%), GLM 5.3 Flash (28.2%), and Kimi K3 (23.1%), with competitive speed and pricing across the board.
