ZenMux
Multi-model aggregator API: 192 models + AI Insurance + Builder Plan from $20/mo + OpenAI/Anthropic/Vertex compatible
Why we recommend ZenMux
Why we recommend ZenMux
ZenMux (zenmux.ai), operated by NexaMind Singapore Pte. Ltd., is positioned as a multi-model API aggregator + AI insurance platform — one account, one API Key, unlocks 192 models: Claude, GPT, Gemini, DeepSeek, Qwen, GLM, Kimi, MiniMax, Doubao, and more. Developers no longer need separate registrations, top-ups, and key maintenance for each model provider — all calls go through a unified OpenAI / Anthropic / Google Vertex protocol surface.
Single domain, multiple product surfaces. ZenMux is one product, but the entry points are split under
zenmux.ai:
- Brand surface (homepage, blog, changelog, pricing overview) — read product features / case studies / roadmap. The "Visit official site" button at the top points here.
- Platform (
zenmux.ai/platform/*) — Studio Chat web conversation, video generation, PAYG billing control panel. The "Subscribe on ZenMux" buttons on the right jump to/pricing/subscription(Builder Plan) or/pricing/pay-as-you-go.All surfaces share one ZenMux account; accounts registered via the invite link automatically receive a 5% service-fee discount.
Model lineup
The 192 models listed on zenmux.ai/models can be filtered by modality / context length / developer / vendor:
| Modality | Count |
|---|---|
| Text | 155 |
| Image | 16 |
| Video | 13 |
| Audio | 3 |
| Transcription | 5 |
| Embeddings | 4 |
| Rerank | 2 |
Each model surfaces context window / max output tokens / supported protocols / cache hit price — so you can compare DeepSeek V4 Flash, GLM 4.6V Flash, GPT-5, Claude Opus 4 side-by-side. Vendor coverage spans OpenAI / Anthropic / Google / Tbox / Alibaba / Baidu / Zhipu / Moonshot / MiniMax / ByteDance / Kuaishou / DeepSeek — whenever a flagship model launches, ZenMux picks it up nearly same-day (the "Latest" tab is the default sort).
Builder Plan subscription
The ZenMux Builder Plan at zenmux.ai/pricing/subscription is the personal-developer subscription. It's the same species as Zhipu Coding Plan / Qwen Token Plan, but with a few distinctive design choices:
- Flow is a floating USD-equivalent unit: 1 Flow = $0.03283 today (≈ 30 Flows = $1), not locked 1:1 to Tokens — quota value auto-adjusts with underlying API cost.
- 5-hour rolling window + 7-day rolling reset: every window has a Flow cap so a single large request can't drain the month.
- AI Insurance compensation: when the model produces hallucination / clearly below-expectation output / high latency / low throughput, ZenMux auto-detects + auto-compensates credits — an industry first.
| Tier | Monthly | 5h Flow | Monthly Flow (USD equiv) | Recommended for |
|---|---|---|---|---|
| Free | $0 / month | 5 (≈ $0.16) | 165.6 (≈ $5.44) | Trying AI capabilities, hands-on basics |
| Starter | $20 / month | 50 (≈ $1.64) | 914 (≈ $30.01) | Daily Vibe Working for PM / marketing / ops |
| Max | $100 / month | 300 (≈ $9.85) | 5,487 (≈ $180.15) | Devs starting their Vibe Coding journey |
| Ultra | $200 / month | 800 (≈ $26.27) | 14,631 (≈ $480.40) | High-intensity Vibe Coding / pro dev |
Note: Builder Plan is limited to personal dev / learning / non-production testing (rate-limited to 10-15 RPM). For production, switch to Pay As You Go (no rate limits, production-grade stability, token-level billing) — first top-up also comes with +10% credit bonus. Subscription and PAYG API Keys are completely independent — you can run both at once; use subscription during development, switch to PAYG at launch with zero migration.
AI Insurance + data flywheel
ZenMux's differentiating pitch is AI Insurance — daily auto-detection → identify problem requests → next-day automatic credit compensation. This isn't marketing copy: every compensated case is sanitized and exposed as a "high-value failure sample" that you can feed into the data flywheel for your own AI product. The public Platform Analytics shows the cumulative token throughput and compensation amount since 2025-09-29.
Smart routing + multi-channel failover
Turn on ZenMux Auto and the system analyzes each prompt's complexity, automatically picking the cheapest-quality model (no more "which model for which task" spreadsheet to maintain). Every model is also backed by multiple provider channels — if one provider fails / rate-limits / is regionally unavailable, the system auto-switches to a backup, so your app sees zero downtime. Combined with Cloudflare's global edge network, latency stays stable worldwide.
