Gemini 3 Pro Review: A Hands-On Test Reveals Underwhelming Performance

The author shares their personal experience using Google’s Gemini 3 Pro, encountering various issues during coding tasks. The model produced numerous errors in front-end development that were difficult to resolve, while Trae CN solo performed better. Its research mode and knowledge base features delivered poor results, with hallucinations and logical errors. The review concludes Gemini is slightly better than DeepSeek (due to multimodal capabilities) but falls far short of the online hype. For personal use, Claude Opus 4.5 is superior with faster response times, followed by GPT-5.1. Conclusion: Gemini 3 Pro delivers mediocre performance, ranking low among AI models.
