CodeGeeX

Based on the evidence, CodeGeeX is a free code assistant by Zhipu AI, now in its fourth generation and ranked among the top five domestic AI coding tools by penetration. An open-source 9B model (CodeGeeX4‑ALL‑9B) is available, and official material claims over 1 million individual users. These signals support adoption as a daily coding helper, but the evidence is drawn largely from launch announcements, tutorials, and reposts rather than extensive third‑party benchmarks or long‑term hands‑on reviews. Caution is warranted when assuming performance parity with commercial Copilot alternatives.

In practice, CodeGeeX provides inline code completion, comment‑driven code generation, cross‑language translation, automatic code commenting, and a conversational Q&A pane inside the IDE. A Zhihu tutorial demonstrated generating a full “Holy Grail” layout with gradient background and live clock in 20 seconds using Chinese comments. This shows the tool effectively reduces boilerplate and lookup time for routine front‑end and scripting tasks. It supports Python, JavaScript, TypeScript, C++, Java, Go, PHP, C#, and many others.
