GPT-5.5

GPT-5.5正式发布：AI能力的又一次飞跃 # 2026年4月底，OpenAI正式发布了GPT-5.5，这是继GPT-5之后最重要的一次模型迭代。对于开发者而言，这不仅仅是一次简单的版本升级——GPT-5.5在推理深度、上下文处理、多模态能力和API设计上都带来了根本性的变革。

GPT-5.5 Is Here: A Quantum Leap in AI Capability # At the end of April 2026, OpenAI officially released GPT-5.5 — the most significant model iteration since GPT-5. For developers, this isn’t just a simple version bump — GPT-5.5 brings fundamental changes to reasoning depth, context handling, multimodal capabilities, and API design. This article dives deep into the technical details of GPT-5.5’s core upgrades, helping developers understand what this release means for their applications and how to migrate efficiently.

GPT-5.5 vs Claude 4.7 vs Gemini 3.0：开发者如何选择最佳模型 # 2026年，大语言模型（LLM）的竞争格局已经发生了翻天覆地的变化。OpenAI的GPT-5.5、Anthropic的Claude 4.7和Google的Gemini 3.0三强鼎立，每一款模型都在性能、定价和功能上有着显著的突破。对于开发者而言，选择合适的模型不再仅仅是看参数大小，而是需要综合考量推理能力、代码生成质量、上下文窗口、API稳定性以及成本效益等多维度因素。

GPT-5.5 vs Claude 4.7 vs Gemini 3.0: How Developers Choose the Best Model in 2026 # In 2026, the large language model (LLM) landscape has undergone a seismic shift. OpenAI’s GPT-5.5, Anthropic’s Claude 4.7, and Google’s Gemini 3.0 form a dominant triad, each making significant breakthroughs in performance, pricing, and capabilities. For developers, choosing the right model is no longer just about parameter counts — it requires a multi-dimensional evaluation of reasoning ability, code generation quality, context windows, API stability, and cost-effectiveness.
