... solve this for my own development workflows, I ve been building a high-speed API relay station. It aggregates models like DeepSeek-V4, Qwen 3.7, GLM 5.1, Kimi 2.6, and Minimax-M2.7, with a primary focus on concurrency and stability. Here is a quick look at the infrastructure under the hood: Routing & Latency: Deployed on optimized acceleration routes (Singapore/US West). The TTFT (Time-To-First-Token) is nearly instant for stream responses. Failover Stability: Built-in enterprise load ... ... word for it, I d love for you to run your own automated benchmarks (llm-benchmark, multi-threading, etc.) and tear it apart. You can test the sandbox here: [Link: model.usddd.org ] To help the PH community test the concurrency
