Judge Opinions

Claude Opus 6.3

"CodeGeeX is the best fully-free coding assistant available, with 1.1M VS Code installs and strong code completion powered by a 9B parameter model that achieves 82.3% HumanEval — remarkable for its size. The critical limitation is the complete absence of agentic capabilities: it cannot autonomously plan, execute terminal commands, or manage multi-file workflows, and the VS Code extension has not been updated since September 2025."

+ Completely free for individual developers with no usage caps, making it the best zero-cost autocomplete option
+ 128K token context window with perfect needle-in-haystack retrieval and cross-lingual code translation across 100+ languages
+ Multiple interaction modes (Stealth autocomplete, Interactive chat, Translation, Prompt templates) cover diverse workflows
+ Open-source 9B model available under Apache 2.0 with self-hosting option via Ollama
- No agentic capabilities whatsoever — cannot execute terminal commands, manage files, or autonomously complete multi-step tasks
- VS Code extension last updated September 2025 — five months with no updates suggests development may have shifted elsewhere
- Struggles with architectural patterns across large codebases despite strong file-level code understanding
- Locked to Zhipu AI's GLM models with no third-party provider support and undisclosed cloud model specifications
GPT-5.2 6.3

"CodeGeeX is an editor-integrated code assistant focused on inline completion and chat-style prompts, with additional modes like code translation and prompt-driven generation. It can be useful for quick snippets and language-to-language conversion without changing your workflow. It’s not built for coordinated multi-file repo edits, and the overall experience can vary by IDE integration and update cadence."

+ Inline completion is quick for small edits, boilerplate, and repetitive patterns
+ Includes modes oriented around translation and prompt-driven code generation
+ Editor-first workflow keeps usage lightweight for day-to-day coding
+ Low barrier to entry for trying AI completion without changing your workflow
+ Good fit for single-file tasks where repo-wide context is not required
- Limited support for multi-file refactors or repo-scale changes
- Model/provider flexibility is constrained, so you have fewer backend options
- Update cadence and public release activity appear less active than rapidly evolving tools
- Feature depth varies across IDEs, making the experience inconsistent
Gemini 3 8.2

"CodeGeeX4 is a standout open-weight coding assistant that delivers surprising performance for its compact 9B parameter size. Capable of running locally via Ollama or vLLM, it offers a privacy-focused, high-speed alternative to cloud-based giants, complete with repository-level context and 'AICommiter' capabilities."

+ Open weights (CodeGeeX4-9B) allow for free, private local usage
+ Extremely fast inference speed due to efficient 9B architecture
+ Supports repository-level Q&A and multi-file logic
+ Strong integration with Ollama and local deployment workflows
- Raw reasoning capability lags behind massive frontier models (GPT-4, Opus)
- 9B parameter limit constrains complex multi-step logic
- Documentation is split between English and Chinese sources
