What is ZenMux?

ZenMux provides a unified API and single-account gateway for accessing leading AI models, including multimodal text, image, audio, and video models.

Supports OpenAI-, Anthropic-, and Google Vertex AI-compatible calls and a GUI for chat, image, and video generation.



Model auto-routing analyzes prompts and historical performance to select models that balance quality and cost.

Built-in insurance automates verified compensation for measurable model failures and returns anonymized failure data for model improvement.



HLE (Human Last Exam) benchmarks are run and published in real time, with on-demand testing for quality monitoring and degradation tracking.

Enterprise features include multi-provider failover, global edge acceleration, token-level tracing, and multi-dimensional dashboards for usage and cost visibility.
