GPT-5.4 刚刚发布。作为重度 Claude Code 用户，我的看法

OpenAI has released GPT-5.4, and as a heavy user of Claude Code for over 12 hours a day, I paid attention to this new model's launch. GPT-5.4 actually ships as three variants: GPT-5.4, GPT-5.4 Thinking, and GPT-5.4 Code. Each variant is tailored for different use cases, with GPT-5.4 serving as a daily driver for chat and code generation, GPT-5.4 Thinking designed for reasoning-heavy tasks, and GPT-5.4 Code focusing on coding and debugging. For developers, this update shows impressive performance across multiple benchmarks, warranting a closer look and utilization.
