OpenCode Tutorial

OpenCode is a command-line (CLI) based AI programming Agent that understands project context and automatically executes development tasks.

OpenCode is not a simple code generator, but rather an intelligent agent tool withUnderstanding + Executioncapabilities.

OpenCode runs in the terminal, not in an IDE.

OpenCode is an Agent (intelligent agent tool), not a Chat (chat tool).

The New Era of AI Programming

In the past, the software development model was: developers write code, and tools provide assistance.

In the AI Agent model, however, the development approach is changing:

  • Developers describe requirements
  • AI is responsible for implementing the code
  • Developers are responsible for review and decision-making

The emergence of such tools marks a shift in the development model from hand-writing code to directing AI to write code.

Compared toGitHub Copilotthese code completion tools, OpenCode goes a step further: it can not only generate code, but also truly execute tasks.
