Recommendations and Introductions to Various AI LLM API Platforms, Updated June 9, 2026- Zeruns's Blog

Recommendations and introductions to various AI Large Language Model (LLM) API aggregation/routing platforms, featuring both domestic and international platforms.

Preface

Entering 2026, the AI large model market remains in a state of "fierce competition." From international models like GPT-5 and Claude 4.5 to the domestic shining stars like DeepSeek R1/V3 and the Qwen3 series, developers and enterprises face a massive pain point amidst such a complex model ecosystem: If you have to individually connect, recharge, and maintain API Keys for each provider, not only are development costs prohibitively high, but financial reimbursement also becomes extremely cumbersome.

Therefore, "API Aggregation/Routing Platforms" (Model Routers) have become the most mainstream solution today. Developers only need to integrate a standard OpenAI-formatted interface to instantly call hundreds of mainstream large models globally. This guide will walk you through the latest and most reliable domestic and international LLM API aggregation platforms in 2026, helping you save time, effort, and money.
