Recommended AI Large Model API Aggregation/Relay Platforms and Introductions: Domestic and International Large Model API Platform Recommendations.

Preface

As we enter 2026, the AI large-model market remains in a state of intense competition. From international models such as GPT-5 and Claude 4.5 to China’s outstanding DeepSeek R1/V3 and Alibaba Cloud’s Tongyi Qianwen Qwen3 series, this vast and complex model ecosystem presents developers and enterprises with a major pain point: if every provider must be connected, topped up, and have its API keys maintained separately, development costs are high and financial reimbursement becomes extremely cumbersome.

Therefore, “API aggregation/relay platforms” (Model Router) have become the most mainstream solution. Developers only need to connect to a single standard OpenAI-format API to instantly access hundreds of mainstream large models around the world. This guide will walk you through the latest and most reliable domestic and international large-model API aggregation platforms in 2026, helping you save time, reduce hassle, and spend less.
