Selection Comparison Table

Recommended Combinations

Personal developers: GitHub Copilot + Bito → high‑precision generation + documentation/test coverage.

Domestic teams: 通义灵码 + CodeGeeX → Chinese support + free and efficient.

Cloud‑focused projects: CodeWhisperer + 通义灵码 → cross‑cloud platform code generation.

Common Installation Steps

IDEA

→ File → Settings → Plugins → search the target plugin name → click Install.

Restart IDE, then follow prompts to log in or configure the API Key.

Precautions

Network issues: International plugins (e.g., Copilot) need stable external access; domestic plugins can connect directly.

Compliance check: Enterprise users should review generated code to avoid intellectual‑property risks.

Performance tuning: If memory is insufficient, disable real‑time suggestions in plugin settings.

Choose tools based on project requirements and personal preference; start with free options (e.g., CodeGeeX) and upgrade to paid plugins for advanced features.
