ZenMux

ZenMux is an API finder tool. A managed gateway to 100+ models from OpenAI, Anthropic, Google, DeepSeek and others, with OpenAI, Anthropic and Vertex compatible APIs, automatic model routing, provider failover, spend analytics, and an insurance scheme that compensates for bad or slow outputs.

ZenMux is a model gateway that puts more than 100 AI models behind a single account, a single API key, and a unified interface. Instead of maintaining separate credentials and billing relationships with each vendor, teams route requests through ZenMux and reach models from OpenAI, Anthropic, Google, DeepSeek, xAI, Qwen, MiniMax, Moonshot AI, Z.ai, Baidu, Volcengine and Kuaishou. The company states that traffic is sourced only from official providers or authorized cloud partners, so you are not calling proxied or degraded copies of a model. The platform is built primarily for developers and product teams shipping AI features. API calls are compatible with the OpenAI, Anthropic and Google Vertex AI protocols, which means existing SDK code often needs only a base URL change. A browser chat interface covers conversational use, image generation and video generation for people who do not want to write code. Two operational features stand out. Model Auto Routing (ZenMux Auto) inspects each prompt and picks the model that should deliver the best quality at the lowest cost, learning from task patterns and historical performance. Multi-provider failover keeps backup channels and capacity reserves for every model, and requests are served through Cloudflare's edge network to reduce latency. The distinctive piece is AI Model Insurance. When a response is hallucinated, unusually slow, or limited by low throughput, ZenMux says it compensates the account automatically rather than only logging the incident. Compensated cases are anonymized and returned as bad-case data that customers can use to improve their own products. Multi-dimensional dashboards track every request, token and cent, and a public analytics page discloses aggregate tokens processed and compensation paid since launch. ZenMux sits in the router and aggregation layer rather than the model layer. Compared with going direct to each vendor, it trades some depth of vendor-specific tooling for consolidated billing, cross-model comparison and resilience. Compared with self-hosted gateways, it shifts operational work to a managed service but adds a dependency on a third party in the request path.
