One OpenAI-compatible gateway for adaptive LLM routing, guardrails, and spend control
Each prompt is graded and routed to the model that clears your quality bar, with configurable fallback chains that retry before a response starts.
Pay provider prices with $0 per-token added on pay-as-you-go and subscriptions, or bring your own provider keys and credits.
PII shielding, jailbreak and injection blocking, and per-call approval for tool and MCP actions run before you are billed.
Request logs, per-prompt receipts, routing and spend dashboards, and copy-as-cURL make every call auditable and attributable.
One unified API for 100+ AI models, with insurance when output disappoints
Access Claude, GPT, Gemini, Grok, DeepSeek, Qwen and more from a single endpoint, sourced from official providers or authorized cloud partners — no proxies and no degraded copies.
Hallucinated output, excessive latency and low throughput are automatically compensated, and each compensated case is anonymized and returned to you as a bad-case sample.
Enable ZenMux Auto and the system analyses each prompt to pick the model that delivers the best quality at the lowest cost, balancing the quality/price trade-off for you.
Multi-provider failover with capacity reserves keeps applications running when a channel rate-limits or fails, while Cloudflare edge acceleration reduces latency worldwide.
