Virtual models are now available on AI Gateway .

A virtual model is a saved configuration that tells AI Gateway which model and settings to use. Your apps and agents call it with a custom model ID, such as vmc/coding-agent . You can change the model or settings centrally in AI Gateway without redeploying your apps or reconfiguring your agents.

Use virtual models to:

Configure coding agents: Set reasoning effort, fast mode, prompt caching, and other options even when your agent doesn’t expose them.

Control routing and compliance: Choose providers, configure fallback models, and enforce requirements such as Zero Data Retention .

Attribute spend: Attach custom reporting tags to every request that uses the virtual model.

To create a virtual model, open the Virtual Models page and click Create Virtual Model .…
