Together Link is a free command-line interface tool that allows users to run open-source models within environments like Claude Code, Codex, and OpenCode. The software is currently in beta and supports installation on macOS and Linux via a single command. It requires a Together API key to function and does not rely on local proxies or daemons.
The tool features a router that assigns tasks based on complexity. Simple fixes are directed to fast, low-cost models, while complex coding tasks are handled by frontier-level models. Users can manually pin specific models using flags. In Claude Code, the interface maps model tiers to open alternatives, such as Kimi K3 and GLM 5.3, each supporting 1M context windows.
Pricing is based on a pay-as-you-go model or credit packs using the user's Together key. Costs for input and output tokens vary by model, with Kimi K3 priced at $3.00 and $15.00 respectively, and GLM 5.3 at $1.40 and $4.40. The system provides real-time spend tracking and displays estimated costs after each session.
As of September 30, 2026, Together reports significant market share for specific models on OpenRouter, including 40.8% for DeepSeek V4.1 Flash, 28.2% for GLM 5.3 Flash, and 23.1% for Kimi K3. The platform aims to reduce the high monthly costs that engineering organizations currently incur by using closed-source models for development tasks.
