I Replaced 4 LLM API Clients With One Endpoint — Here's What the Latency Data Actually Looks Like

Managing four different LLM APIs in the same project is the kind of thing that starts small and becomes a maintenance sinkhole. Four sets of credentials, four error-handling branches, four SDK versions to pin, and a requirements file that looks like it's auditioning for a dependency museum. I finally got tired of it on a Friday afternoon and decided to try Token Router. Token Router is a single API endpoint that proxies to 50+ models - Claude, GPT-4o, Gemini, Llama, and all behind one key. You change one string to switch models. That's the pitch. Here's whether it holds up.
