opencode zen

AI models recommended for developers by the opencode team

Overview

What it is

opencode is an open-source AI coding agent built for the terminal. It features a native TUI, multi-session support, and is model-agnostic, letting you use Claude, OpenAI, Google, or even local models.

Intent

I need it when

Get started quickly with AI-assisted coding without complex setup or configuration of multiple LLM providers

OpenCode Zen simplifies onboarding by offering a curated list of pre-tested models; users can run the /connect command, sign in at opencode.ai/auth, add billing details, and paste their API key to immediately access validated models optimized for coding tasks.

Access reliable, pre-tested AI models optimized specifically for code generation without worrying about inconsistent performance across different LLM providers

OpenCode Zen provides a handpicked set of AI models that have been tested and benchmarked by the OpenCode team specifically for coding agents, eliminating the need to evaluate and validate models independently while ensuring consistent quality and performance.

Use a single AI coding agent across multiple development environments (terminal, IDE, desktop) without switching tools

OpenCode Zen integrates with OpenCode, which is available as a terminal interface, desktop app (beta on macOS, Windows, Linux), and IDE extensions (VS Code, Cursor, Zed, Windsurf), allowing developers to access the same validated models across their preferred development environment.

Write and modify code in a privacy-first environment where code and context data are never stored on external servers

OpenCode Zen operates through OpenCode, which does not store any code or context data, allowing all processing to happen locally or through direct API calls to the user's chosen AI provider, making it suitable for privacy-sensitive environments and organizations with strict data governance requirements.

Leverage existing AI subscriptions (GitHub Copilot, ChatGPT Plus/Pro) or connect to any of 75+ LLM providers without vendor lock-in

OpenCode Zen allows users to log in with GitHub Copilot, OpenAI ChatGPT Plus/Pro, or connect to any model from 75+ LLM providers through Models.dev, including local models, providing flexibility to use existing subscriptions or preferred providers while benefiting from Zen's pre-validated model selection.

Drop

Not a fit when

  • User requires a fully managed AI service without needing to configure LLM provider API keys
  • Organization needs guaranteed SLA and support contracts for production coding assistance
  • User prefers proprietary, closed-source AI coding solutions over open-source alternatives
  • Team lacks technical expertise to set up and manage terminal-based or IDE extension tools
  • Project requires real-time collaborative coding with multiple simultaneous users in a single session
