LLM Providers - Aster Agents

Overview

Aster Agents lets you bring your own model credentials. Add API keys and endpoints for OpenAI, Anthropic, Google, Azure OpenAI, AWS Bedrock, xAI, or Fireworks AI.

Adding a provider

Navigate to Control Hub → Providers (/control-hub/providers)
Click Add Provider and pick a service.
Enter the required fields (API key, base URL, deployment name, etc.).
Hit Save. Credentials are encrypted at rest.

Add LLM provider credentials

Providers hold the credentials. The Models page (/control-hub/models) is where you manage model instances — most notably Azure deployments — once a provider is connected.

Supported fields

Provider	Required	Optional
OpenAI	API key	—
Azure OpenAI	API key, plus either a resource name or a custom base URL	API version, legacy deployment name
Anthropic	API key	—
Google Generative AI	API key	—
Google Vertex AI	Project ID, Location, JSON key	—
AWS Bedrock	Access key ID, Secret access key, Region	Session token
xAI	API key	—
Fireworks AI	API key	—

See Choosing a Model for the models each provider exposes.

⚠️ Agents inherit provider credentials at runtime. Make sure to set sensible usage limits and monitor spend in each provider dashboard.

Rotating keys

Click the ••• menu next to a provider.
Choose Rotate Key and paste the new credential.
Confirm – agents using that key will pick up the change immediately.

Removing a provider

Deleting a provider breaks any model instance that depends on it. Double-check agent configurations before removal.
