What ZenMux is

ZenMux gives developers one API and API key for accessing AI models from providers including OpenAI, Anthropic, Google, and DeepSeek. It supports OpenAI-compatible and Anthropic-compatible protocols. Its routing analyzes requests and task characteristics to choose a model based on suitability and cost, and it says it can switch providers when one is at capacity or experiencing service issues. API logs and analytics cover cost, usage, and performance. The free plan offers web-only Studio Chat with basic models and 5 Flows per 5 hours, but no API access. Starter costs $20 a month and adds API access with 50 Flows per 5 hours. Max costs $100 a month and Ultra costs $200 a month; both include API access and larger Flow allowances. Integrations listed include Claude Code, CodeX, Cline, VS Code Copilot, OpenCode, Cherry Studio, Obsidian, Dify, and Open WebUI. Subscription plans have a 10–15 RPM limit and rolling quota windows; ZenMux says Builder subscriptions are for personal development and learning, not production or commercial products.
