OpenAI’s GPT 5.2, while promising enhanced AI coding capabilities, struggles to meet the high expectations set against competitors like Google’s Gemini 3 and Anthropic’s Opus 4.5. Hands-on tests reveal that GPT 5.2 excels in generating functional code but falters in advanced design quality and fast performance. Gemini 3 is preferred for tasks demanding visual precision, while Opus 4.5 outperforms GPT 5.2 in speed and versatility, making it more reliable for developers. Despite its integration with OpenAI’s ecosystem offering a user-friendly experience, GPT 5.2 may not be the optimal choice for those requiring high-level design or rapid outputs. For developers seeking speed, Opus 4.5 is ideal; for design-focused projects, Gemini 3 prevails. As AI coding technology advances, developers should stay informed about new models and features to leverage AI’s full potential in software development.
