CodeGeeX - Performance and Accuracy
Performance and Accuracy of CodeGeeX
CodeGeeX, developed by the Knowledge Engineering Group at Tsinghua University, is a multilingual code generation model that has demonstrated impressive performance and accuracy in various coding tasks.Code Generation
CodeGeeX outperforms other notable code generation models such as InCoder and CodeGen in several key metrics. On the HumanEval-X benchmark, CodeGeeX achieves the highest average performance across different programming languages, with an average pass rate of 54.76% compared to 54.39% for CodeGen-Multi-16B, despite being competitive with larger-scale models.Multilingual Capabilities
CodeGeeX excels in multilingual code generation, allowing it to transform a program into any expected language with high accuracy. It performs well in translating code across different programming languages, although it shows preferences for certain languages; for example, it is particularly good at translating other languages to Python and C .Budget Distribution and Diversity
By distributing the generation budget across multiple languages, CodeGeeX can improve the diversity of generated samples, increasing the chance of producing at least one correct answer. This approach has been shown to improve the pass rate significantly, with a heuristic allocation based on the language distribution in the training corpus yielding the best results.Crosslingual Code Translation
In code translation tasks, CodeGeeX demonstrates strong zero-shot and fine-tuned performance. The fine-tuned version, CodeGeeX-13B-FT, shows improved performance on specific translation tasks, although there are observations that the model’s performance can vary depending on the language pairs involved.Chain-of-Thought and Function Call Capabilities
The CodeGeeX4-ALL-9B model, a more advanced version, showcases remarkable performance in code reasoning, understanding, and execution. It supports function call capabilities and achieves a better execution success rate than GPT-4. Additionally, it excels in tasks requiring chain-of-thought prompting, a method that enhances its ability to generate desired programs with fewer examples.Limitations and Areas for Improvement
Language Preferences
While CodeGeeX performs well across various languages, it has a preference for certain languages, which can affect its performance in specific translation tasks. For instance, it is better at translating to Python and C but less so for JavaScript and Go.Error Handling and Context Focus
Users have suggested improvements such as adding a ‘Focus’ function to allow the model to concentrate on specific scripts or code fragments, which could enhance its accuracy in providing solutions. Additionally, integrating real-time error detection and correction capabilities, similar to Error Lens, could further improve its usability.Fine-Tuning and Few-Shot Learning
While CodeGeeX shows strong performance, there is still room for improvement in its few-shot learning capabilities. Exploring methods like chain-of-thought prompting can help, but further research is needed to optimize these aspects without relying on costly fine-tuning approaches. In summary, CodeGeeX is a highly accurate and versatile code generation model with strong multilingual capabilities. However, it has some limitations, particularly in handling certain language pairs and in real-time error detection, which are areas that can be addressed through further development and user feedback.
