OpenCode is a powerful AI coding agent built specifically for the terminal, offering a native TUI experience with LSP support and multi-session capabilities. This guide shows you how to combine OpenCode with powerful open source models on Together AI like Kimi K2.7 Code and GLM 5.2 to supercharge your development workflow directly from your terminal. With OpenCode’s agent, you can ask it to build features, fix bugs, explain codebases, and start new projects – all while maintaining full transparency in terms of cost and token usage. Here’s how you can start using it with Together AI’s models:

​
1. Install OpenCode

Install OpenCode directly from your terminal with a single command:
This will install OpenCode and make it available system-wide.

​
2. Launch OpenCode

Navigate to your project directory and launch OpenCode:
OpenCode will start with its native terminal UI interface, automatically detecting and loading the appropriate Language Server Protocol (LSP) for your project.

​
3. Configure Together AI

When you first run OpenCode, you’ll need to configure it to use Together AI as your model provider. Follow these steps:
  • Set up your API provider: Configure OpenCode to use Together AI
    • opencode auth login

  • Add your API key: Get your Together AI API key and paste it into the opencode terminal
  • Select a model: Choose from powerful models like:
    • moonshotai/Kimi-K2.7-Code - Purpose-built for coding agents.
    • zai-org/GLM-5.2 - Strong coding and agentic all-rounder.
    • deepseek-ai/DeepSeek-V4-Pro - Advanced reasoning capabilities.
    • Qwen/Qwen3-Coder-Next-FP8 - Fast, cost-effective coding model.

​
4. Bonus: install the opencode vs-code extension

For developers who prefer working within VS Code, OpenCode offers a dedicated extension that integrates seamlessly into your IDE workflow while still leveraging the power of the terminal-based agent. Install the extension: Search for “opencode” in the VS Code Extensions Marketplace or directly use this link:

​
Key features & usage

​
Native terminal experience

OpenCode provides a responsive, native terminal UI that’s fully themeable and integrated into your command-line workflow.

​
Plan mode vs build mode

Switch between modes using the Tab key:
  • Plan Mode: Ask OpenCode to create implementation plans without making changes
  • Build Mode: Let OpenCode directly implement features and make code changes
Use the @ key to fuzzy search and reference files in your project:

​
Best practices

​
Give detailed context

Talk to OpenCode like you’re talking to a junior developer:

​
Use examples and references

Provide plenty of context and examples:

​
Iterate on plans

In Plan Mode, review and refine the approach before implementation:
