OpenCode is both a CLI + TUI AI coding agent that runs in your terminal and a plugin that integrates with editors like VS Code. It enables fast code generation, debugging, project analysis, file operations, and cross-project collaboration across different development environments. OpenCode becomes far more cost-effective with the GLM Coding Plan — delivering greater efficiency and stability for your development workflow. Description
