Production-Grade Selection Guide for OpenAI-Compatible APIs: From Multi-Model Agent Orchestration and Tool Calling Compatibility to Compute and Channe

In an era of multi-model mixing and deep Agent production use, 'OpenAI-compatible API support' is only the starting point. This article breaks down the core criteria for selecting an OpenAI-compatible API for production from four dimensions: protocol edge behaviors (Function Calling, streaming chunks, multimodal parameter passing), hybrid architecture for open-source and closed-source models, underlying supply transparency, and per-Key isolation with explicit 429 rate limiting governance.

How to Integrate Agent APIs: Four Verification Points from Framework Configuration to Tool Calling

AI Agents rely on the underlying model's native tool calling for multi-turn reasoning; when integrating OpenAI-compatible APIs, verify four key points: passthrough support for tools parameters, complete long-context retention, clear rate limits, and state tracking after tool returns.

How to Write a Tool Calling API? Four-Layer Cross-Model Differences and the Loop Skeleton

This article provides a portable tool calling loop skeleton, breaking down four layers of differences across models: function declarations, trigger control, return structure, and multi-step termination, along with adapter design, verification methods, and a regression checklist.
