Introduction
ZenMux is an Large Language Models (LLMs) “multiplexer” platform for enterprises. It lets you call many models (OpenAI, Anthropic, Google, DeepSeek, etc.) through a single, unified API, compatible with both the OpenAI and Anthropic protocols. It adds intelligent provider routing (and failover) for each model, detailed observability on cost/usage/performance, and a novel insurance mechanism that automatically detects degraded quality (e.g., hallucinations or high latency) and issues payouts.
