In a practical test to evaluate AI models' capabilities in building a Tetris game, Claude Opus 4.5 from Anthropic delivered a smooth, playable game on the first attempt, showcasing its efficiency and user-friendly experience. GPT-5.2 Pro from OpenAI, despite its high cost and extended reasoning capabilities, produced a bug-ridden game initially, requiring additional prompts to fix issues, yet still offering a less satisfying user experience. DeepSeek V3.2, while the most cost-effective option, failed to deliver a playable game on the first try but remains a viable choice for developers on a budget willing to invest time in debugging. This comparison highlights Opus 4.5 as the most reliable for day-to-day coding tasks, while DeepSeek offers budget-friendly solutions with some effort, and GPT-5.2 Pro is better suited for complex reasoning tasks rather than simple coding projects. This matters because it helps developers choose the right AI model for their needs, balancing cost, efficiency, and user experience.
