Together Link CLI Runs Open Models Like Kimi K3 and GLM 5.3 Inside Claude Code, Codex, and OpenCode

Together Link is a new free command-line interface tool that enables developers to substitute open models — including Kimi K3 and GLM 5.3 — as the inference backend inside popular AI coding environments like Claude Code, Codex CLI, and OpenCode. The tool works by proxying requests from these coding agents to Together AI's inference endpoints, allowing teams to use cost-effective or specialized open models without abandoning their existing agentic coding workflows. This is practically significant because it decouples the coding agent interface from the underlying model, giving developers model flexibility without retooling their entire development environment. Teams concerned about cost, data privacy, or wanting to benchmark open models against closed ones in real coding tasks can now do so with minimal friction. Together Link represents a broader trend of open-model compatibility layers that reduce lock-in to proprietary AI coding tools.
