Editor Review

To move existing calls onto this gateway, keep the current client and change the base address and key. The compatible protocols are OpenAI, Anthropic, and Google Vertex, so message format in application code can stay close to what you have. If you do not want to pick a model each time, turn on auto routing and let the system choose from the prompt. To lock one provider, still name the model in the request. The dashboard records tokens and cost per request. A failed channel moves to a backup. The page says hallucinations, slowness, or low throughput are compensated automatically, which does not replace checking the business answer. It fits engineering teams that want one model entry and a clear usage record.

What is ZenMux

ZenMux is a gateway that puts many models behind one account and one API. The page says models come from official providers or authorized cloud partners. Calls follow OpenAI, Anthropic, and Google Vertex protocols, and the site also offers chat, image, and video. Requests record tokens and cost. If a channel is rate-limited or fails, traffic moves to a backup, and a nearby edge node takes the request. With auto routing on, the system picks a model from the prompt. The page says it compensates hallucinated output, excessive latency, or low throughput.

ZenMux Key Features

  • One API for many models

    One account maps to one API, compatible with OpenAI, Anthropic, and Google Vertex protocols, with models from official or authorized channels.

  • Automatic model choice

    With auto routing on, the system reads the prompt and picks a model for that call, so the model name does not have to be edited every time.

  • Fail over to another channel

    Each model keeps more than one provider channel. If one is rate-limited or unavailable, the request moves to a backup and is served from a nearby node.

  • Usage records and result compensation

    Tokens and cost for each request can be traced on the dashboard. Hallucinated output, high latency, or low throughput can be compensated under the page rules.

ZenMux Key Advantages

  • One account and one API can call models through OpenAI, Anthropic, or Vertex protocols
  • Auto routing picks a model from the prompt, and a request can still name a model
  • Rate limits or channel failures move the call to a backup channel
  • The dashboard records tokens and cost per request, and hallucinations or slowness can be compensated

ZenMux Use Cases

  • Point an existing client at the gateway

    A backend engineer keeps the existing chat client, changes the address and key, and lets a support bot keep its current message format.

  • Let the prompt choose the model

    An application owner turns on auto routing, lets the system pick a model for questions of different lengths, and checks each cost on the dashboard.

Frequently Asked Questions

▶How much of my current client code has to change?

The page shows keeping the current client, pointing the address at ZenMux, and using a key from this account. Protocols follow OpenAI, Anthropic, and Google Vertex, so the message shape can usually stay. Name the model in the request to lock one, or turn on auto routing to choose less often. The site also has chat, image, and video for people who are not calling the API. The key and address still have to be set by you. They are not written into an old project automatically.

▶What does compensation cover when a result is poor?

The site limits compensation to hallucinated output, excessive latency, and low throughput, and it says compensated cases can come back as anonymized bad examples for improving your own app. They sit with the usage dashboard next to tokens and cost for each request. That does not mean a person rewrites the business answer. Channel failures are handled separately by an automatic backup. Whether compensation applies, and how it is calculated, follows the rules on the page at the time.
