📄 中文摘要
在构建人工智能应用时，开发者通常需要管理多个 API 密钥，例如 OpenAI 的 GPT-4o、Anthropic 的 Claude、Google 的 Gemini 以及 DeepSeek 的密钥。这些不同的提供商各自有独立的仪表盘、计费方式、SDK 特性和速率限制，切换模型时需要更改导入、认证和请求格式。为了解决这一问题，API 网关提供了一种简化的解决方案。通过 API 网关，开发者只需一个密钥、一个端点和一个 SDK，即可访问所有 AI 模型，极大地简化了开发流程。
一个 API 密钥，624+ 人工智能模型：如何在不管理多个账户的情况下使用 GPT-4o、Claude、Gemini 和 DeepSeek

One API Key, 624+ AI Models: How to Use GPT-4o, Claude, Gemini & DeepSeek Without Managing Multiple Accounts
Developers building AI applications often face the challenge of managing multiple API keys from various providers, such as OpenAI for GPT-4o, Anthropic for Claude, Google for Gemini, and DeepSeek. Each provider has its own dashboard, billing methods, SDK peculiarities, and rate limits, making it cumbersome to switch models as it requires changing imports, authentication, and sometimes the entire request format. To address this issue, an API gateway offers a simplified solution. With an API gateway, developers can use a single key, a single endpoint, and a single SDK to access all AI models, significantly streamlining the development process.
