ZenMux
ZenMux provides one API and API key for accessing AI models from OpenAI, Anthropic, Google, DeepSeek, and other providers.
What ZenMux is
ZenMux provides one API and API key for accessing AI models from OpenAI, Anthropic, Google, DeepSeek, and other providers. It supports OpenAI-compatible and Anthropic-compatible protocols. Intelligent routing evaluates requests and task characteristics to choose models based on suitability and cost, while provider failover can switch traffic when a provider has capacity or service problems. API logs and analytics cover cost, usage, and performance. ZenMux also describes an insurance mechanism that reviews call data daily for poor performance, hallucinations, or excessive latency, with payouts credited the next day. The free plan costs $0 and includes web-only Studio Chat, basic models, and 5 Flows per 5 hours, without API access. Subscription plans have 10–15 RPM limits, whereas Pay As You Go has no per-minute or concurrency limits. Builder subscriptions are not for production or commercial products.
Good

Watch out
- Free plan has no API access
- Subscription plans have 10–15 RPM limits
- Builder subscriptions exclude production and commercial use
Who it suits
ZenMux suits developers who want one interface for multiple AI model providers and routing options. Free access fits web experimentation, while paid plans add API use and higher Flow allowances.
Verdict
ZenMux centralizes model access with routing, failover, and usage visibility. Review plan limits and the Builder restriction before using it for an application or business service.
