Every deployed model has its own API Keys tab where you generate a key scoped to that model, then call its endpoint directly, from curl, your own backend, or any OpenAI-compatible client.
This works on any deployed model, a router like benchgen-router-lite, a model you uploaded, or one you fine-tuned in Train. If you don’t have a deployed model yet, see Deploy an Inference Model.

​
Step 1: Open your model

In Models, find the model you want a key for, it needs to be Deployed or Running to serve an endpoint. Here, benchgen-router-lite is running.

Open it. Its card has four tabs: Model Card, Usage, API Keys, and Evaluations. Notice the sidebar on the right already carries an API key field with a Generate key shortcut, that same control is there no matter which tab you’re on.

​
Step 2: The quick way, or the full API Keys tab

Click that sidebar Generate key button any time you just need a key fast. For naming keys or seeing everything you’ve already issued, click the API Keys tab instead, it’s the same action dialog either way, just with more around it.

The API Keys tab: endpoint, key name field, Generate key, and a table of existing keys

Optionally name the key (useful if you’re issuing separate keys per app or environment), then click + Generate key.

​
Step 3: Copy the key now, it won’t be shown again

A dialog shows your new secret key plus a ready-to-run example request.
A dialog titled Your new API key, warning that only a hash is stored so the key cannot be recovered later, with the secret key, a Copy button, and an example curl request against the chat completions endpoint

The new API key dialog: the secret key, a Copy button, and an example curl request using it

Copy it now. BenchGen stores only a hash of the key, so if you close this dialog without saving it, you can’t recover it, you’d have to generate a new one. If a key is ever exposed, revoke it and generate a replacement.
Click Copy to grab just the key, or copy the example request as-is:
Click I have saved it to dismiss the dialog.

​
Managing keys afterward

Your new key appears in the table on the API Keys tab, Active, with its creation date, last-used timestamp, and running spend. Click Revoke on any key you no longer want live, it flips to a Revoked status immediately and stops authenticating.

A revoked key: status changes to Revoked and its Revoke button disappears

​
Watching it get used

Every call made with the key rolls up into the model’s Usage tab: total requests, tokens, spend, and average latency, plus a log of every individual request.
The Usage tab showing 2 requests, 175 tokens, $0.001526 spend, 4066 ms average latency, and a Requests table with two successful calls

Click any row to see that exact call in full: its tags, request details, token and cost metrics, and the actual prompt and response.

Next Steps

Monitor Model Usage

Track requests, tokens, spend, and inspect individual calls made with your key.

BenchGen Router Lite

Point your key at the router endpoint instead of a single model.
