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.

MCP协议实战：2026年构建AI Agent的终极教程 # 2026年，MCP（Model Context Protocol）已经成为AI Agent开发的事实标准。本文将从协议原理、服务端实现、客户端集成到生产部署，全方位带你掌握这一关键技术。

MCP Protocol in Practice: The Ultimate Guide to Building AI Agents in 2026 # In 2026, the Model Context Protocol (MCP) has become the de facto standard for AI Agent development. This guide takes you from protocol fundamentals to production deployment — covering server implementation, client integration, XiDao gateway routing, and real-world practices with Claude 4.7, GPT-5.5, and beyond.

Introduction # In 2026, Anthropic released Claude 4.7 — a landmark model that pushes the boundaries of reasoning, code generation, multimodal understanding, and long-context processing. For developers, knowing how to efficiently and reliably integrate the Claude 4.7 API into production systems is now an essential skill. This guide walks you through everything: from your first API call to production-grade deployment, covering the latest API changes, pricing structure, and battle-tested best practices.

引言 # 2026年，Anthropic推出了全新的Claude 4.7模型，在推理能力、代码生成、多模态理解和长上下文处理等方面均实现了重大突破。对于开发者而言，如何高效、稳定地接入Claude 4.7 API，并将其应用于生产环境，已成为一项关键技能。

策略一：选择合适的模型 # 不是所有任务都需要最贵的模型。核心原则：用最便宜的模型完成任务。 策略二：优化提示词 # 优化后 token 数量减少 70%+。
