In this video, I'll be comparing GPT 5.5, Deepseek V4, and Opus 4.7 across a series of coding and frontend benchmarks to see which model performs best in real-world tasks, how they handle complex UI generation, and whether the new Deepseek and OpenAI releases live up to the hype. -- Key Takeaways: 🚀 Deepseek V4 launches with a massive context window and very aggressive pricing. 🤖 GPT 5.5 shows improvements in token efficiency and some coding tasks, but still has UI issues. 🎨 Opus 4.7 performs the best overall on complex frontend and 3D tasks. 🧪 KingBench 2.0 is designed to test models across multiple coding scenarios, not just agentic workflows. 🏗️ The video includes tests like an elevator simulator, a ThreeJS contact lens case, and a folding table. 🍔 The models are also tested on SVG generation, a bow and arrow simulator, and a math question. 💸 A pricing breakdown shows how Deepseek is much cheaper than GPT 5.5 on API. 🏆 Overall, Opus 4.7 comes out as the strongest model, while Deepseek underperforms and GPT 5.5 is mixed.
