AI Ping

AI Ping is a neutral, third-party LLM API evaluation and routing platform built by Qingcheng Intelligence. It aggregates 550+ models from over 30 providers behind a single OpenAI-compatible API, eliminating the need to deal with multiple vendor integrations. Underpinned by Tsinghua-affiliated technology and guided by Academician Zheng Weimin as chief scientific advisor, it also serves as the official data display for the 2025 LLM Service Performance Ranking released by the China Software Testing Center and Tsinghua University. The platform continuously monitors latency, throughput, time-to-first-token, and output accuracy 24/7, visualizing real-time performance so developers can move beyond blind selection. Its intelligent routing automatically directs each request to the most stable, lowest-latency, and cheapest provider path; tests have shown a 37% API cost reduction and 9% throughput improvement while avoiding single-provider failures. As a relay layer, AI Ping introduces a slight network hop. Routing decisions rely on fresh monitoring data and may lag during rapid fluctuations. Model coverage is currently focused on Chinese providers with limited overseas options.
